sapiens 212-215 26712119-5 2016 SUMMARY: BACKGROUND: Elevated plasma interleukin-10 (IL-10) levels were observed in patients who responded less to clopidogrel (a prodrug that is required for further metabolic bioactivation in the liver). clopidogrel 116-127 interleukin 10 Homo sapiens 54-59 26712119-7 2016 OBJECTIVE: To systematically explore possible differences in the formation of and response to clopidogrel active metabolite (CAM) in mice with or without IL-10 gene expression. clopidogrel 94-105 interleukin 10 Mus musculus 154-159 26712119-8 2016 METHODS: A single oral dose of clopidogrel (10 mg kg(-1)) was given to IL-10 knockout (KO) mice and wild-type (WT) control mice, respectively, and pharmacokinetic parameters of clopidogrel and CAM were calculated. clopidogrel 31-42 interleukin

serum levels of MCP-1, IL-1beta, and IL-10. clopidogrel 7-18 interleukin 10 Rattus norvegicus 126-131 27555873-1 2016 Clopidogrel resistance from CYP2C19 polymorphism has been associated with stent thrombosis in patients undergoing percutaneous coronary intervention with drug-eluting stents. clopidogrel 0-11 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 28-35 27555873-5 2016 Although he was compliant with his dual antiplatelet therapy, he developed stent thrombosis, which was confirmed as clopidogrel resistance from homozygous CYP2C19 polymorphism. clopidogrel 116-127 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 155-162 26984587-3 2016 Indeed, dual antiplatelet therapy (DAPT) with aspirin and the P2Y12inhibitor clopidogrel, which has represented the mainstay of treatment for many years, has significantly reduced the incidence of recurrent atherothrombotic events. clopidogrel 77-88 purinergic receptor P2Y12 Homo sapiens 62-67 26444255-5 2016 Cangrelor blocks the binding to the platelet P2Y12 receptor of the active metabolite of the thienopyridines, clopidogrel and prasugrel. clopidogrel 109-120 purinergic receptor P2Y12 Homo sapiens 45-50 26815196-14 2016 Co-administration of omeprazole or esomeprazole in patients treated with clopidogrel results in lower CYP2C19 enzyme activity and increased platelet reactivity as measured by VASP phosphorylation test while patients given pantoprazole or ranitidine did not show any significant changes in CYP2C19 enzyme activity and platelet reactivity. clopidogrel 73-84 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 102-109 26815196-14 2016 Co-administration of omeprazole or esomeprazole in patients treated with clopidogrel results in lower CYP2C19 enzyme activity and increased platelet reactivity as measured by VASP phosphorylation test while patients given pantoprazole or ranitidine did not show any significant changes in CYP2C19 enzyme activity and platelet reactivity. clopidogrel 73-84 vasodilator stimulated phosphoprotein Homo sapiens 175-179 26815196-14 2016 Co-administration of omeprazole or esomeprazole in patients treated with clopidogrel results in lower CYP2C19 enzyme activity and increased platelet reactivity as measured by VASP phosphorylation test while patients given pantoprazole or ranitidine did not show any significant changes in CYP2C19 enzyme activity and platelet reactivity. clopidogrel 73-84 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 289-296 26365936-1 2016 BACKGROUND AND AIM: High platelet reactivity (HPR) and presence of CYP2C19 loss-of-function alleles are associated with higher risk for periprocedural myocardial infarction in clopidogrel-treated patients undergoing percutaneous coronary intervention (PCI). clopidogrel 176-187 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 67-74 27411384-6 2016 Further analysis showed that 53.3% of patients carrying the CYP2C19*2 gene variant had clopidogrel-HTPR, while in the wild type group there were 14.6% (p<0.001). clopidogrel 87-98 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 60-67 27411384-7 2016 Multivariate logistic regression analysis identified the CYP2C19*2 variant allele (OR 4.384; 95% CI 1.296-14.833, p=0.017) and high total cholesterol level (OR 2.090; 95% CI 1.263-3.459, p=0.004) as the only independent risk factors for clopidogrel-HTPR. clopidogrel 237-248 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 57-64 27411384-8 2016 CONCLUSION: The CYP2C19*2 gene variant and high total cholesterol level were major factors for clopidogrel- HTPR in patients with carotid artery stenosis undergoing CEA. clopidogrel 95-106 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 16-23 26573281-0 2016 Impact of Cytochrome P450 2C19*2 and *3 on Clopidogrel Loading Dose in Saudi Patients with Acute Coronary Syndrome. clopidogrel 43-54 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 10-30 26573281-1 2016 BACKGROUND: Emerging evidence shows that clopidogrel is greatly affected by nonfunctioning alleles measured by P2Y12 or platelet reactivity units (PRU). clopidogrel 41-52 purinergic receptor P2Y12 Homo sapiens 111-116 26453463-6 2016 CONCLUSIONS: The current study suggests that switching to a novel P2Y12 agent in patients with ACS and/or patients undergoing coronary stenting is more efficacious than continuing clopidogrel. clopidogrel 180-191 purinergic receptor P2Y12 Homo sapiens 66-71 26635063-7 2016 Concomitant use of PPIs with thienopyridines (e.g. clopidogrel) could be justified in patients without strong affinity to cytochrome CYP2C19 and with high risk of bleeding (e.g. patients with prior upper gastrointestinal bleeding, Helicobacter pylori infection, advanced age, steroid treatment, and nonsteroidal anti-inflammatory drug use). clopidogrel 51-62 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 133-140 26824050-0 2016

NFE2 like bZIP transcription factor 2 Homo sapiens 104-108 26695516-0 2016 P-Glycoprotein Polymorphism C3435T Is Associated with Dose-Adjusted Clopidogrel and 2-Oxo-Clopidogrel Concentration. clopidogrel 68-79 ATP binding cassette subfamily B member 1 Homo sapiens 0-14 26695516-8 2016 CONCLUSION: The ABCB1 3435CC genotype is associated with increased clopidogrel and 2-oxo-clopidogrel dose-adjusted concentrations. clopidogrel 67-78 ATP binding cassette subfamily B member 1 Homo sapiens 16-21 26695516-9 2016 Therefore, the ABCB1 C3435T genotyping should be one of the parameters taken into account when deciding about the dosing regimen of clopidogrel. clopidogrel 132-143 ATP binding cassette subfamily B member 1 Homo sapiens 15-20 26721703-6 2016 Interestingly, recent findings indicate that the acyl-beta-glucuronides of gemfibrozil and clopidogrel cause metabolism-dependent inactivation of CYP2C8, leading to a strong potential for drug interactions. clopidogrel 91-102 cytochrome P450 family 2 subfamily C member 8 Homo sapiens 146-152 25927944-1 2016 High and low platelet reactivity, HPR and LPR respectively, to clopidogrel and aspirin have previously been associated with adverse events following percutaneous coronary intervention (PCI). clopidogrel 63-74 haptoglobin-related protein Homo sapiens 34-37 25927944-8 2016 We found an association between the cumulative number of PREDICT score variables and the incidence of HPR for clopidogrel (HPR (ADP)) (p < 0.001) and aspirin (HPR (AA)) (p = 0.007). clopidogrel 110-121 haptoglobin-related protein Homo sapiens 102-105 25927944-8 2016 We found an association between the cumulative number of PREDICT score variables and the incidence of HPR for clopidogrel (HPR (ADP)) (p < 0.001) and aspirin (HPR (AA)) (p = 0.007). clopidogrel 110-121 haptoglobin-related protein Homo sapiens 123-126 25927944-8 2016 We found an association between the cumulative number of PREDICT score variables and the incidence of HPR for clopidogrel (HPR (ADP)) (p < 0.001) and aspirin (HPR (AA)) (p = 0.007). clopidogrel 110-121 haptoglobin-related protein Homo sapiens 123-126 26083485-9 2016 VASP phosphorylation and AA-induced platelet aggregation showed fair correlation in patients taking clopidogrel only. clopidogrel 100-111 vasodilator stimulated phosphoprotein Homo sapiens 0-4 26270719-5 2016 All P2Y12 antagonists studied resulted in strong P2Y12 receptor blockade (cangrelor: 93.6%; clopidogrel AM: 93.0%; prasugrel AM: 97.9%). clopidogrel 92-103 purinergic receptor P2Y12 Homo sapiens 4-9 26270719-8 2016 In conclusion, in vitro cangrelor strongly inhibits the binding of clopidogrel and prasugrel AMs to the P2Y12 receptor, consistent with the previous observation of a negative pharmacodynamic interaction. clopidogrel 67-78 purinergic receptor P2Y12 Homo sapiens 104-109 26367336-1 2016 Previously conducted studies revealed that smoking enhanced the efficacy of clopidogrel by increasing formation of the active metabolite (AM) from the prodrug through induction of the cytochrome CYP1A2. clopidogrel 76-87 cytochrome P450 family 1 subfamily A member 2 Homo sapiens 195-201 27980542-3 2016 The safety and efficacy of prasugrel and ticagrelor taken with oral anticoagulants also remain to be established in randomized trials; therefore the P2Y12 inhibitor clopidogrel on top of aspirin or without is now recommended to be used together with a VKA or NOAC. clopidogrel 165-176 purinergic receptor P2Y12 Homo sapiens 149-154 26610376-11 2016 No specific predictors were found to be significantly associated with ST. New P2Y12 inhibitors were associated with more ST compared to clopidogrel (17.3% vs. 4.2%; respectively, p=0.05). clopidogrel 136-147 purinergic receptor P2Y12 Homo sapiens 78-83 28356861-0 2016 Influence of Cyp2c19*2 Gene Variant on Therapeutic Response During Clopidogrel Treatment in Patients with Carotid Artery Stenosis. clopidogrel 67-78 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 13-20 28356861-2 2016 The aim of our study was to determine the influence of CYP2C19*2 loss-of-function variant allele on clopidogrel responsiveness in patients with carotid artery stenosis. clopidogrel 100-111 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 55-62 28356861-7 2016 The influence of CYP2C19*2 variant allele on clopidogrel platelet reactivity was determined using multiple-electrode aggregometry (MEA). clopidogrel 45-56 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 17-24 28356861-13 2016 CONCLUSIONS: The CYP2C19*2 loss-of-function variant allele has significant influence on clopidogrel response in patients with carotid artery stenosis undergoing endarterectomy. clopidogrel 88-99 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 17-24 27012029-12 2016 The mean VASP-PRI in the patient group treated with clopidogrel was significantly lower than that in the control group without antiplatelet therapy (54.88 +/- 16.81% vs. 79.86 +/- 10.24%, p < 0.001). clopidogrel 52-63 vasodilator stimulated phosphoprotein Homo sapiens 9-13 27590033-1 2016 Dual antiplatelet therapy (DAPT) with acetylsalicylic acid and a P2Y12 inhibitor (clopidogrel, ticagrelor, or prasugrel) reduces thrombotic events in patients with acute coronary syndrome (ACS), but it is also associated with an increased risk of bleeding complications. clopidogrel 82-93 purinergic receptor P2Y12 Homo sapiens 65-70 27239927-3 2016 They initially received dual antiplatelet therapy: clopidogrel 75 mg + acetylsalicylic acid (ASA) 300 mg. Genetic testing was performed in all the patients to reveal the carriage of allelic variants of the genes of cytochrome P-450 isoenzymes and the efficiency of antiplatelet therapy was evaluated. clopidogrel 51-62 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 215-231 26423110-4 2016 Our objectives were (i) to demonstrate that the proportion of "rapid" metabolisers on 75 mg of clopidogrel within 30-208 (PRU) of P2Y12 inhibition is non-inferior to "slow" metabolisers on prasugrel 10 mg and (ii) to evaluate the same end-point after switching drugs. clopidogrel 95-106 purinergic receptor P2Y12 Homo sapiens 130-135 26553698-0 2015 Efficacy of ex vivo autologous and in vivo platelet transfusion in the reversal of P2Y12 inhibition by clopidogrel, prasugrel, and ticagrelor: the APTITUDE study. clopidogrel 103-114 purinergic receptor P2Y12 Homo sapiens 83-88 25855780-4 2015 Administration of clopidogrel bisulfate, an irreversible inhibitor of P2Y12-R, significantly increased urine concentration and AQP2 protein in the kidneys of Sprague-Dawley rats. clopidogrel 18-39 purinergic receptor P2Y12 Rattus norvegicus 70-75 25855780-4 2015 Administration of clopidogrel bisulfate, an irreversible inhibitor of P2Y12-R, significantly increased urine concentration and AQP2 protein in the kidneys of Sprague-Dawley rats. clopidogrel 18-39 aquaporin 2 Rattus norvegicus 127-131 25855780-6 2015 Clopidogrel administration also significantly ameliorated lithium-induced polyuria, improved urine concentrating ability and AQP2 protein abundance, and reversed the lithium-induced increase in free-water excretion, without decreasing blood or kidney tissue lithium levels. clopidogrel 0-11 aquaporin 2 Rattus norvegicus 125-129 26527225-11 2015 Regarding safety, medium-dose aspirin (100-300 mg daily) and aspirin/clopidogrel combination showed an increased risk of MB compared with warfarin (RR 1.17 and 1.15, respectively), as per dabigatran 150 mg and rivaroxaban in older elderly (RR 1.17 and 1.12, respectively). clopidogrel 69-80 ribonucleotide reductase catalytic subunit M1 Homo sapiens 148-152 26527225-11 2015 Regarding safety, medium-dose aspirin (100-300 mg daily) and aspirin/clopidogrel combination showed an increased risk of MB compared with warfarin (RR 1.17 and 1.15, respectively), as per dabigatran 150 mg and rivaroxaban in older elderly (RR 1.17 and 1.12, respectively). clopidogrel 69-80 ribonucleotide reductase catalytic subunit M1 Homo sapiens 240-244 26398625-3 2015 Noncarriers of the CYP2C19 loss-of-function (LOF) allele received clopidogrel 75 mg daily. clopidogrel 66-77 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 19-26 26398625-5 2015 CYP2C19 LOF allele(s) carriers who were intermediate metabolizers (IM) received high-dose clopidogrel (225 mg daily) and were tested for high on-treatment platelet reactivity (HTPR). clopidogrel 90-101 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 0-7 26398625-9 2015 Sensitivity analyses found universal clopidogrel to be the preferred strategy if the prevalence of the CYP2C19 LOF allele was less than 2.6% or the incidence of HTPR in IM patients was greater than 82.8%. clopidogrel 37-48 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 103-110 26663068-1 2015 OBJECTIVE: To assess the association of genetic polymorphisms of CYP2C19*2,*3,*17 with the recurrence risk of ischemic stroke during clopidogrel prevention in ethnic Han Chinese from Fujian Province. clopidogrel 133-144 cytochrome P450 family 2 subfamily C member

sapiens 51-58 24945780-7 2014 RESULTS: The catalytic activity of CYP2C19.10 in the biotransformation of clopidogrel and 2-oxo-clopidogrel was significantly decreased relative to the wild-type CYP2C19.1B. clopidogrel 74-85 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 35-42 24945780-7 2014 RESULTS: The catalytic activity of CYP2C19.10 in the biotransformation of clopidogrel

CONCLUSIONS: Our data provide evidence that CYP2C19.10 variant partially metabolizes clopidogrel and 2-oxo-clopidogrel, and the presence of CYP2C19*10 allele affects the CY2C19*2 TaqMan genotyping assay and results in misclassification of CYP2C19*10/*2 as CYP2C19*2/*2. clopidogrel 85-96 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 44-51 24945780-9 2014 CONCLUSIONS: Our data provide evidence that CYP2C19.10 variant partially metabolizes clopidogrel and 2-oxo-clopidogrel, and the presence of CYP2C19*10 allele affects the CY2C19*2 TaqMan genotyping assay and results in misclassification of CYP2C19*10/*2 as CYP2C19*2/*2. clopidogrel 85-96 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 140-147 24945780-9 2014 CONCLUSIONS: Our data provide evidence that

CYP2C19*2/*2. clopidogrel 85-96 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 140-147 24718389-4 2014 The aim of the ISAR-HPR registry was to assess whether clopidogrel-treated HPR patients benefit from selective intensification of P2Y12 receptor inhibition. clopidogrel 55-66 purinergic receptor P2Y12 Homo sapiens 130-135 24951432-1 2014 The P2Y12 inhibitors, clopidogrel, prasugrel, and ticagrelor, are administered in fixed doses without laboratory monitoring. clopidogrel 22-33 purinergic receptor P2Y12 Homo sapiens 4-9 24951432-4 2014 Patients treated with standard-dose clopidogrel have substantial variability in platelet inhibition, which is partly explained by genetic polymorphisms encoding CYP2C19, the hepatic enzyme involved in biotransformation of clopidogrel to its active metabolite. clopidogrel 36-47 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 161-168 24951432-4 2014 Patients treated with standard-dose clopidogrel have substantial variability in platelet inhibition, which is partly explained by genetic polymorphisms encoding CYP2C19, the hepatic enzyme involved in biotransformation of clopidogrel to its active metabolite. clopidogrel 222-233 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 161-168 25117329-6 2014 We were able to correctly infer genotypes for the warfarin-related loci VKORC1 and

the CYP2C19*1 haplotype, increased the stringency of bioequivalence statistics and resulted in bioinequivalence of a generic clopidogrel compound that otherwise proved equivalent when tested in an open unselected population. clopidogrel 182-193 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 61-68 24202700-1 2014 To investigate the relationship between circulating microRNA 223

subfamily C member 19 Homo sapiens 103-110 24665827-7 2014 RESULTS: (1) PF4/H antibody-positive patients suffered a significantly higher incidence of thrombosis than those who were antibody-negative; (2) PF4/H antibody-positive patients who survived a thrombosis manifested a significantly longer bleeding time and decreased maximum percentage of platelet aggregation inhibition; (3) aspirin and clopidogrel decreased the incidence of thrombosis in PF4/H antibody-positive patients by inhibiting platelet activation. clopidogrel 337-348 platelet factor 4 Homo sapiens 145-148 24665827-7 2014

24856643-11 2014 CONCLUSION: The results of this pilot study of treatment of patients in the early phase of ACS indicate that CYP2C19*2 POC genotyping might help to identify patients at risk with poor response to clopidogrel treatment, thereby benefiting from reloading and switching to alternative P2Y12 receptor inhibition. clopidogrel 196-207 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 109-116 24856643-11 2014 CONCLUSION: The results of this pilot study of treatment of patients in the early phase of ACS indicate that CYP2C19*2 POC genotyping might help to identify patients at risk with poor response to clopidogrel treatment, thereby benefiting from reloading and switching to alternative P2Y12 receptor inhibition. clopidogrel 196-207 purinergic receptor P2Y12 Homo

Homo sapiens 11-15 24762860-1 2014 BACKGROUND: Clopidogrel is recommended after acute myocardial infarction but has variable efficacy and safety, in part related to the effect of cytochrome P450 (CYP) polymorphisms on its metabolism. clopidogrel 12-23 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 144-159 24762860-1 2014 BACKGROUND: Clopidogrel is recommended after acute myocardial infarction but has variable efficacy and safety, in part related to the effect of cytochrome P450 (CYP) polymorphisms on its metabolism. clopidogrel 12-23 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 161-164 24762860-8 2014 CONCLUSIONS: Both loss-of-function and gain-of-function CYP polymorphisms affecting clopidogrel metabolism are associated with increased mortality among clopidogrel-treated patients after acute myocardial infarction; the specific polymorphism and the putative mechanism vary according to race. clopidogrel 84-95 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 56-59 24762860-8 2014 CONCLUSIONS: Both loss-of-function and gain-of-function CYP polymorphisms affecting clopidogrel metabolism are associated with increased mortality among

clopidogrel 23-34 paraoxonase 1 Homo sapiens 199-203 24763934-10 2014 CONCLUSIONS: Our results suggest that antiplatelet response to clopidogrel in the late phase depends on the CYP3A5 polymorphism in

observations, we hypothesised that VN-P2Y12 overestimates the therapeutic effects of clopidogrel. clopidogrel 105-116 purinergic receptor P2Y12 Homo sapiens 58-63 24671606-7 2014 In 59 patients loaded with clopidogrel 600 mg/900 mg, a greater proportion had a "therapeutic response" with VN-P2Y12 compared to s-TEG, regardless of the threshold for defining HPR with VN-PY12 (P2Y12 reaction units >= 230 or 208). clopidogrel 27-38 purinergic receptor P2Y12 Homo sapiens 112-117 24671606-10 2014 This could have implications for the ability of VN-P2Y12 to stratify patients as "responders" or

Homo sapiens 17-24 25606414-2 2014 Single nucleotide polymorphisms (SNPs) such as CYP2C19*2 and ABCB1 C3435T have been found to play a role in different individual responses to clopidogrel. clopidogrel 142-153 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 47-54 25606414-2 2014 Single nucleotide polymorphisms (SNPs) such as CYP2C19*2 and ABCB1 C3435T have been found to play

cilostazol combination therapy, galectin-3 level, lipoprotein-associated phospholipase A2 gene expression, and RhoA/ROCK-related protein expression in peripheral blood mononuclear cells were significantly suppressed (all p<0.01). clopidogrel 25-36 phospholipase A2 group VII Homo sapiens 91-130 23981082-5 2014 Loss-of-function polymorphisms in CYP2C19 are the strongest individual variables affecting pharmacokinetics and antiplatelet response to clopidogrel, but explain no more than 5 to 12% of the variability in adenosine diphosphate-induced platelet aggregation on clopidogrel. clopidogrel 137-148 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 34-41 23981082-5 2014 Loss-of-function polymorphisms in CYP2C19 are the strongest individual variables affecting

database for all patients who were non-responders to clopidogrel, defined as P2Y12% inhibition <30%, despite repeat clopidogrel loading dose of at least 600 mg, and who were then administered ticagrelor. clopidogrel 94-105 purinergic receptor P2Y12 Homo sapiens 118-123 24670650-4 2014 P2Y12R regulates platelet activation and thrombus formation, and several antithrombotic drugs targeting P2Y12R--including the prodrugs clopidogrel (Plavix) and prasugrel (Effient) that are metabolized and bind covalently, and the nucleoside analogue ticagrelor (Brilinta) that acts directly on the receptor--have been approved for the prevention of stroke and myocardial infarction. clopidogrel 135-146 purinergic receptor P2Y12 Homo sapiens 104-110 24670650-4 2014 P2Y12R regulates platelet activation and thrombus formation, and several antithrombotic drugs targeting P2Y12R--including the prodrugs clopidogrel (Plavix) and prasugrel (Effient) that are metabolized and bind covalently, and the nucleoside analogue ticagrelor (Brilinta) that acts directly on the receptor--have been approved for the prevention of stroke and myocardial infarction. clopidogrel 148-154 purinergic receptor P2Y12 Homo sapiens 104-110 24670650-5 2014 However, limitations of these drugs (for example, a very long half-life of clopidogrel action and a characteristic adverse effect profile of ticagrelor) suggest that there is an unfulfilled medical need for developing a new generation of P2Y12R inhibitors. clopidogrel 75-86 purinergic receptor P2Y12 Homo sapiens 238-244 24956245-0 2014 Clopidogrel

with CYP2C19*2, 150 mg daily of clopidogrel was associated with improved ADP-specific platelet inhibition (217 vs 258 P2Y12 reaction units, p = 0.01). clopidogrel 44-55 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 17-24 24956245-4 2014 In patients with CYP2C19*2, 150 mg daily of clopidogrel was associated with improved ADP-specific platelet inhibition (217 vs 258 P2Y12 reaction units, p = 0.01). clopidogrel 44-55 purinergic receptor P2Y12 Homo sapiens 130-135 24918808-7 2014 Because comparative studies indicate that omeprazole and esomeprazole have a greater effect on the CYP2C19-mediated conversion of clopidogrel to its active metabolite and, consequently, clopidogrel"s effect on platelet reactivity, FDA labeling recommends avoiding omeprazole and esomeprazole in patients taking clopidogrel. clopidogrel 130-141 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 99-106 24918808-7 2014 Because comparative studies indicate that omeprazole and esomeprazole have a greater effect on the CYP2C19-mediated conversion of clopidogrel to its active metabolite and, consequently, clopidogrel"s effect on platelet reactivity, FDA labeling recommends avoiding omeprazole and esomeprazole in patients taking clopidogrel. clopidogrel 186-197 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 99-106 24918808-7 2014 Because comparative studies indicate that omeprazole and esomeprazole have a greater effect on the CYP2C19-mediated conversion of clopidogrel to its active metabolite and, consequently, clopidogrel"s effect on platelet

clopidogrel 103-114 purinergic receptor P2Y12 Homo sapiens 125-130 24719135-6 2014 The antiplatelet activity of clopidogrel was measured by VerifyNow P2Y12 assay in the same patient while medicated with CCBs and at 8 weeks after discontinuation of CCBs. clopidogrel 29-40 purinergic receptor P2Y12 Homo sapiens 67-72 24998658-1 2014 OBJECTIVE: To investigate the relation of clopidogrel resistance to polymorphism of adenosine diphosphate receptor (P2Y12). clopidogrel 42-53 purinergic receptor P2Y12 Homo sapiens 116-121 24998658-10 2014 CONCLUSION: T-34, -52 mutations on P2Y12 receptor gene may be a risk factor for clopidogrel resistance and adverse cardiovascular events. clopidogrel 80-91 purinergic receptor P2Y12 Homo sapiens 35-40 24636274-8 2014 As recipients of ticlopidine and

interaction that seems to exist between clopidogrel and omeprazole or esomeprazole has been shown to be clinically important in research published since the 2006 review; this effect is not seen as a class effect of PPIs. clopidogrel 61-72 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 4-11 24336012-5 2014 RESULTS: Clopidogrel therapy resulted in a significant reduction in soluble CD40 ligand (P = 0.03), a prothrombotic and proinflammatory molecule derived mainly from activated platelets. clopidogrel 9-20 CD40 molecule Homo sapiens 76-80 23849748-1 2014 BACKGROUND: Concern has

23849748-5 2014 METHODS: A retrospective review of all patients with stroke and transient ischemic attack (TIA) tested for the clopidogrel CYP2C19 genotype was performed, with a collection of data including race/ethnicity, CYP2C19 status, and the presence of recurrent vascular events. clopidogrel 111-122 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 123-130 24535487-1 2014 OBJECTIVE: Carboxylesterase 1 hydrolyzes the majority of clopidogrel to the inactive metabolite. clopidogrel 57-68 carboxylesterase 1 Homo sapiens 11-29 24535487-2 2014 The aim of this study was to assess the effects of the CES1A2 A(-816)C polymorphism and other genetic and clinical factors on clopidogrel response variability. clopidogrel 126-137 carboxylesterase 1 pseudogene 1 Homo sapiens 55-61 24535487-13 2014 CONCLUSION: The CES1A2 -816C and the CYP2C19 LOF alleles were associated with attenuated platelet reactivity to clopidogrel. clopidogrel 112-123 carboxylesterase 1 pseudogene 1 Homo sapiens 16-22 24535487-13 2014 CONCLUSION: The CES1A2 -816C and the CYP2C19 LOF alleles were associated with attenuated platelet reactivity to clopidogrel. clopidogrel 112-123 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 37-44 24336891-8 2014 Platelet surface expression of CX3CR1 was increased in CHF rats, who displayed an impaired response to clopidogrel (platelet reactivity to ADP: CHF 30 +- 22%; Sham: 8 +- 5%, p<0.05). clopidogrel 103-114 C-X3-C motif chemokine receptor 1 Rattus norvegicus 31-37 24336891-9 2014 Similarly in humans with CHF, elevated fractalkine levels were accompanied by reduced clopidogrel responsiveness. clopidogrel 86-97 C-X3-C motif chemokine ligand 1 Homo sapiens 39-50 24336891-10 2014 Patients with high on-clopidogrel treatment platelet P2Y12 reactivity displayed higher fractalkine levels (1525 +- 487 pg/ml) than those with sufficient clopidogrel response (684 +- 315 pg/ml, p<0.01). clopidogrel 22-33 purinergic receptor P2Y12 Homo sapiens 53-58 24336891-10 2014 Patients with high on-clopidogrel treatment platelet P2Y12 reactivity displayed higher fractalkine levels (1525 +- 487 pg/ml) than those with sufficient clopidogrel response (684 +- 315 pg/ml, p<0.01). clopidogrel 22-33 C-X3-C motif chemokine ligand 1 Homo sapiens 87-98 24336891-12 2014 Fractalkine diminished endothelial function beyond the impairment already observed in CHF and was associated with a reduced responsiveness to the platelet inhibitor clopidogrel. clopidogrel 165-176 C-X3-C motif chemokine ligand 1 Homo sapiens 0-11 24336898-0 2014 Thrombin-induced platelet-fibrin clot strength: relation to high on-clopidogrel platelet reactivity, genotype, and post-percutaneous coronary intervention outcomes. clopidogrel 68-79 coagulation factor II, thrombin Homo sapiens 0-8 24440142-0 2014 Impact of CYP2C19 polymorphism and proton pump inhibitors on platelet reactivity to clopidogrel and clinical outcomes following stent implantation. clopidogrel 84-95 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 10-17 24986003-9 2014 Previous antiplatelet agent - clopidogrel is ineffective due to genetic polymorphism in P450 (polymorphism of CYP2C19 and CYP3A4 allele - *1 isoforms in function, *2 and *3 non-functioning alleles) and due to failure of metabolic conversion to active molecule. clopidogrel 30-41 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 110-117 24986003-9 2014 Previous antiplatelet agent - clopidogrel is ineffective due to genetic polymorphism in P450 (polymorphism of CYP2C19 and CYP3A4 allele - *1 isoforms in function, *2 and *3 non-functioning alleles) and due to failure of metabolic conversion to active molecule. clopidogrel 30-41 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 122-128 24638017-12 2014 Clopidogrel also prevented vascular remodeling, evidenced by augmented media thickness in aortas from Ang II-hypertensive rats. clopidogrel 0-11 angiogenin Rattus norvegicus 102-105 24638017-13 2014 Clopidogrel has beneficial effects on the aortic endothelium of Ang II-hypertensive rats, but its effects do not seem to be directly related to the presence of P2Y12 receptors in this vessel. clopidogrel 0-11 angiogenin Rattus norvegicus 64-67 24477682-0 2014 Clopidogrel preserves whole kidney autoregulatory behavior in ANG II-induced hypertension. clopidogrel 0-11 angiogenin Rattus norvegicus 62-65 24477682-1 2014 This study tested the hypothesis that P2Y12 receptor blockade with clopidogrel preserves renal autoregulatory ability during ANG II-induced hypertension. clopidogrel 67-78 purinergic receptor P2Y12 Rattus norvegicus 38-43 24477682-1 2014 This study tested the hypothesis that P2Y12 receptor blockade with clopidogrel preserves renal autoregulatory ability during ANG II-induced hypertension. clopidogrel 67-78 angiotensinogen Rattus norvegicus 125-131 24477682-2 2014 Clopidogrel was administered orally to male Sprague-Dawley rats chronically infused with ANG II. clopidogrel 0-11 angiotensinogen Rattus norvegicus 89-95 24477682-5 2014 However, clopidogrel treatment preserved autoregulatory behavior in ANG II-treated rats to levels indistinguishable from normotensive sham-operated (sham) rats (autoregulatory index: 0.04 +- 0.14). clopidogrel 9-20 angiogenin Rattus norvegicus 68-71 24477682-7 2014 Clopidogrel significantly reduced renal infiltration of T cells by 39 +- 9% and prevented interstitial artery thickening, ANG II-induced damage to the glomerular basement membrane, deposition of collagen type I, and tubulointerstitial fibrosis, despite the maintenance of hypertension. clopidogrel 0-11 angiotensinogen Rattus norvegicus 122-128 24477682-8 2014 These data demonstrate that systemic P2Y12 receptor blockade with clopidogrel protects against impairment of autoregulatory behavior and renal vascular injury in ANG II-induced hypertension, possibly by reducing renal T cell infiltration. clopidogrel 66-77 purinergic receptor P2Y12 Rattus norvegicus 37-42 24477682-8 2014 These data demonstrate that systemic P2Y12 receptor blockade with clopidogrel protects against impairment of autoregulatory behavior and renal vascular injury in ANG II-induced hypertension, possibly by reducing renal T cell infiltration. clopidogrel 66-77 angiotensinogen Rattus norvegicus 162-168 24609741-2 2014 Thus, GP IIb-IIIa inhibitors could favour endogenous thrombolysis by reducing thrombus growth and preventing thrombus re-formation through competitive inhibition with fibrinogen and, due to their mechanism of action, are likely to have a more profound antiplatelet effect with more rapid onset than conventional antiplatelet agents, such as aspirin or clopidogrel. clopidogrel 352-363 integrin subunit alpha 2b Homo sapiens 6-12 24630752-3 2014 Until recently, clopidogrel was the key P2Y12 antagonist advocated, but due to several limitations as an antiplatelet agent, newer drugs with more predictable, rapid and potent effects have been developed. clopidogrel 16-27 purinergic receptor P2Y12 Homo sapiens 40-45 23834376-6 2014 For carriers of the PlA2 allele, OR 0.924 (n = 2318; 95% CI 0.743, 1.151; P = 0.481) was observed for resistance to any antiplatelet drug, OR 0.862 (n = 2085; 95% CI 0.685, 1.086; P = 0.208) for resistance to aspirin and OR 1.429 (n = 233; 95% CI 0.791, 2.582; P = 0.237) for resistance to clopidogrel. clopidogrel 290-301 phospholipase A2 group IB Homo sapiens 20-24 24323317-10 2014 Furthermore, blocking EP3 reduced murine pulmonary embolism and intensified platelet inhibition by clopidogrel leaving tail bleeding times unchanged. clopidogrel 99-110 prostaglandin E receptor 3 (subtype EP3) Mus musculus 22-25 24322971-4 2014 Nevertheless, VKORC1, CYP2C9, and CYP4F2 variants have been associated with warfarin dose requirements, and CYP2C19 variants have been associated with perturbed antiplatelet response to clopidogrel. clopidogrel 186-197 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 108-115 24632932-5 2014 PARTICIPANTS 18 patients taking clopidogrel, a drug metabolized by CYP2C19.

pump inhibitor and histamine H2 receptor antagonists markedly suppressed the gastric bleeding and lesion responses to ASA plus clopidogrel under histamine-stimulated acid secretion, but had no effect on the responses to acidified ASA plus clopidogrel. clopidogrel 177-188 histamine receptor H 2 Rattus norvegicus 69-90 23782140-13 2014 In contrast, antisecretory drugs such as a proton pump inhibitor and histamine H2 receptor antagonists markedly suppressed the gastric bleeding and lesion responses to ASA plus clopidogrel under histamine-stimulated acid secretion, but had no effect on the

adjustment for number of patients exposed was higher in women (RR 1.40; 95 % CI, 1.00-1.96). clopidogrel 33-44 ribonucleotide reductase catalytic subunit M1 Homo sapiens 156-160 24337310-2 2014 Dual antiplatelet therapy composed of aspirin plus a third generation P2Y12 inhibitor (prasugrel or ticagrelor) represents the gold standard, while aspirin plus second generation P2Y12 inhibitor (clopidogrel) may be used as an alternative in the presence of contraindications for third generation P2Y12 inhibitors and/or a high risk of bleeding. clopidogrel 196-207 purinergic receptor P2Y12 Homo sapiens 179-184 24337310-2 2014 Dual antiplatelet therapy composed of aspirin plus a third generation P2Y12 inhibitor (prasugrel or ticagrelor) represents the gold standard, while aspirin plus

correlated with the presence of cardiovascular disease, hypertension, and HbA1c levels and the administration of clopidogrel and ACEi or ARBs. clopidogrel 135-146 acrosin Homo sapiens 0-3 24406062-3 2014 Whereas the irreversible P2Y12 receptor inhibitors clopidogrel and prasugrel are prodrugs requiring cytochrome P450 (CYP) enzymes for metabolic activation, such activation is not necessary for the direct-acting reversible P2Y12 receptor inhibitor ticagrelor. clopidogrel 51-62 purinergic receptor P2Y12 Homo sapiens 25-30 24406062-7 2014 In general, concomitant administration of P2Y12

hyporesponsive to a routine clopidogrel doses the potency of additional LD and higher MD of clopidogrel is compromised by presence of CYP2C19*2 allele. clopidogrel 53-64 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 159-166 25060201-12 2014 CONCLUSIONS: In patients hyporesponsive to a routine clopidogrel doses the potency of additional LD and higher MD of clopidogrel is

efficacy of the P2Y12 receptor antagonist clopidogrel in reducing cardiovascular events is more pronounced in smokers than in non-smokers. clopidogrel 86-97 purinergic receptor P2Y12 Homo sapiens 60-65 24518848-3 2014 Most probably, this is due to induction of cytochrome p450 1A2 by smoking, which accelerates conversion of clopidogrel to its active metabolite. clopidogrel 107-118 cytochrome

23830212-2 2013 Moreover, carriers of the loss-of-function allele of CYP2C19 polymorphism (CYP2C19*2) display significantly lower responses to clopidogrel. clopidogrel 127-138 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 53-60 23830212-2 2013 Moreover, carriers of the loss-of-function allele of CYP2C19 polymorphism (CYP2C19*2) display significantly lower responses to clopidogrel. clopidogrel 127-138 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 75-82 23830212-3 2013 In this study, we investigated the association between CYP2C19*2 genotype, PPI intake and clopidogrel resistance in patients with coronary artery disease (CAD) and their effect on clinical outcome. clopidogrel 90-101 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 55-62

receptor P2Y12 Homo sapiens 20-25 23844259-3 2013 OBJECTIVES: To develop a P2Y12-specific platelet aggregation test and to compare it with other methods used for monitoring clopidogrel therapy. clopidogrel 123-134 purinergic receptor P2Y12 Homo sapiens 25-30 23844259-5 2013 The effect of clopidogrel was tested by a newly developed ADP(PGE1) aggregation test in which prostaglandin E1 treated platelets are used. clopidogrel 14-25 WD and tetratricopeptide repeats 1 Homo sapiens 58-66 23905638-6 2013 Recently, P2Y12 receptor antagonists more potent than clopidogrel (e.g., prasugrel and ticagrelor) have been approved for patients with acute coronary syndromes and those undergoing percutaneous coronary interventions; these drugs provide greater platelet inhibition than clopidogrel. clopidogrel 272-283 purinergic receptor P2Y12 Homo sapiens 10-15 23816027-0 2013 Relation between the vasodilator-stimulated phosphoprotein phosphorylation assay and light transmittance aggregometry in East Asian patients after high-dose clopidogrel loading. clopidogrel 157-168 vasodilator stimulated phosphoprotein Homo sapiens 21-58 23872648-11 2013 CONCLUSIONS: In patients with ACS, the CYP2C19 LOF allele was associated with post-procedure HTPR and a subsequently increased risk of adverse clinical events at one-year follow-up following DES implantation and clopidogrel administration. clopidogrel 212-223 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 39-46 23474843-1 2013 The aim of this study is to investigate the effect of CYP2C19 polymorphism and cotherapy with rabeprazole or esomeprazole on the antiplatelet effect of clopidogrel. clopidogrel 152-163 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 54-61 23652407-6 2013 Furthermore, clopidogrel and seven other drugs were shown to inhibit OATP1B1-mediated uptake of cerivastatin. clopidogrel 13-24 solute carrier organic anion transporter family member 1B1 Homo sapiens 69-76 23623170-2 2013 Since activated platelets respond stronger to additional stimuli, the extent of endogenous thrombin generation may in part be responsible for the reported response variability to aspirin and clopidogrel therapy. clopidogrel 191-202 coagulation factor II, thrombin Homo sapiens 91-99 23726091-6 2013 RESULTS: Both CYP2C19*2 and *3 alleles were significantly associated with higher platelet aggregation after 5 days maintenance dose of clopidogrel administration (P<0.00001 and P=0.042, respectively). clopidogrel 135-146 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 14-21 23726091-12 2013 CONCLUSION: In clopidogrel treated Chinese patients with ACS, carriers of at least one CYP2C19 loss-of-function allele could predict greater risk of HPR, with the impact mainly attributing to CYP2C19*2. clopidogrel 15-26 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 87-94 23726091-12 2013 CONCLUSION: In clopidogrel treated Chinese patients with ACS, carriers of at least one CYP2C19 loss-of-function allele could predict greater risk of HPR, with the impact mainly attributing to CYP2C19*2. clopidogrel 15-26 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 192-199 23853364-2 2013 It has been suggested that clopidogrel may be less effective in inhibiting platelet aggregation among patients who are carriers of CYP2C19*2 and CYP2C19*3, two loss-of-function CYP2C19 alleles, which are associated with reduced conversion of clopidogrel to its active metabolite. clopidogrel 27-38 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 131-138 23853364-2 2013 It has been suggested that clopidogrel may be less effective in inhibiting platelet aggregation among patients who are carriers of CYP2C19*2 and CYP2C19*3, two loss-of-function CYP2C19 alleles, which are associated with reduced conversion of clopidogrel to its active metabolite. clopidogrel 27-38 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 145-152 23853364-2 2013 It has been suggested that clopidogrel may be less effective in inhibiting platelet aggregation among patients who are carriers of CYP2C19*2 and CYP2C19*3, two loss-of-function CYP2C19 alleles, which are associated with reduced conversion of clopidogrel to its active metabolite. clopidogrel 27-38 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 145-152 23853364-2 2013 It has been suggested that clopidogrel may be less effective in inhibiting platelet aggregation among patients who are carriers of CYP2C19*2 and CYP2C19*3, two loss-of-function CYP2C19 alleles, which are associated with reduced conversion of clopidogrel to its active metabolite. clopidogrel 242-253 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 131-138 23853364-2 2013 It has been suggested that clopidogrel may be less effective in inhibiting platelet aggregation among patients who are carriers of CYP2C19*2 and CYP2C19*3, two loss-of-function CYP2C19 alleles, which are associated with reduced conversion of clopidogrel to its active metabolite. clopidogrel 242-253 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 145-152 23853364-2 2013 It has been suggested that clopidogrel may be less effective in inhibiting platelet aggregation among patients who are carriers of CYP2C19*2 and CYP2C19*3, two loss-of-function CYP2C19 alleles, which are associated with reduced conversion of clopidogrel to its active metabolite. clopidogrel 242-253 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 145-152 22709725-10 2013 While several polymorphisms influence platelet activity, CYP2C19 variants are the most consistently linked to clopidogrel responsiveness. clopidogrel 110-121 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 57-64 22075408-3 2013 It has been shown that besides CYP2C19, CYP2C9 is involved in the hepatic biotransformation of clopidogrel to its active metabolite. clopidogrel 95-106 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 31-38 22075408-3 2013 It has been shown that besides CYP2C19, CYP2C9 is involved in the hepatic biotransformation of clopidogrel to its active metabolite. clopidogrel 95-106 cytochrome P450 family 2 subfamily C member 9 Homo sapiens 40-46 22075408-4 2013 Consequently, CYP2C9 polymorphisms may also affect the extent of clopidogrel-mediated platelet inhibition. clopidogrel 65-76 cytochrome P450 family 2 subfamily C member 9 Homo sapiens 14-20 22075408-5 2013 We therefore studied the influence of CYP2C9 allelic variants on clopidogrel-mediated platelet inhibition as assessed by 5 platelet function tests. clopidogrel 65-76 cytochrome P450 family 2 subfamily C member 9 Homo sapiens 38-44 22075408-10 2013 CONCLUSION: Results from the VerifyNow P2Y12 assay are significantly influenced by CYP2C9 LOF variants leading to decreased clopidogrel-mediated platelet inhibition and an increased rate of HRPR. clopidogrel 124-135 purinergic receptor P2Y12 Homo sapiens 39-44 22075408-10 2013 CONCLUSION: Results from the VerifyNow P2Y12 assay are significantly influenced by CYP2C9 LOF variants leading to decreased clopidogrel-mediated platelet inhibition and an increased rate of HRPR. clopidogrel 124-135 cytochrome P450 family 2 subfamily C member 9 Homo sapiens 83-89 23579966-11 2013 Similarly, CYP2C19 polymorphisms have been associated with clopidogrel resistance in vitro, and have shown an association with stent thrombosis, but not with other cardiovascular outcomes in a consistent manner. clopidogrel 59-70 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 11-18 23612493-2 2013 P2Y12 receptor is the major platelet receptor that mediates ADP-induced aggregation, P2Y12 receptor inhibitors such as clopidogrel and prasugrel inhibit platelet aggregation, and thus, they are used in the treatment and prevention of coronary artery disease. clopidogrel 119-130 purinergic receptor P2Y12 Homo sapiens 0-5 23612493-2 2013 P2Y12 receptor is the major platelet receptor that mediates ADP-induced aggregation, P2Y12 receptor inhibitors such as clopidogrel and prasugrel inhibit platelet aggregation, and thus, they are used in the treatment and prevention of coronary artery disease. clopidogrel 119-130 purinergic receptor P2Y12 Homo sapiens 85-90 23549239-5 2013 Doses greater than clopidogrel 150 mg daily are required to sufficiently overcome high reactivity in CYP2C19 loss-of-function (LOF) allele carriers. clopidogrel 19-30 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 102-109 23940995-1 2013 Objective of this study was to assess platelet response to clopidogrel and its association with certain single nucleotide polymorphisms (SNPs) of the P2RY12 gene. clopidogrel 59-70 purinergic receptor P2Y12 Homo sapiens 150-156 23474908-12 2013 Hence, 12 months of ACS treatment using ticagrelor/ASA instead of clopidogrel/ASA may offer a cost-effective therapeutic option, even when the generic price for clopidogrel is employed. clopidogrel 161-172 1-aminocyclopropane-1-carboxylate synthase homolog (inactive) Homo sapiens 20-23 23940995-3 2013 Pharmacological response to clopidogrel is mediated by the P2Y12 platelet receptor, therefore, SNPs of the P2RY12 gene may account for some of the observed variability in the cardiovascular risk. clopidogrel 28-39 purinergic receptor P2Y12 Homo sapiens 107-113 23940995-11 2013 Our results suggest that 18C > T SNP of the P2RY12 gene may be an independent predictor of pharmacological response to clopidogrel. clopidogrel 122-133 purinergic receptor P2Y12 Homo sapiens 47-53 23149816-2 2013 Clopidogrel is a prodrug which requires a two-step hepatic biotransformation thanks to the cytochrome P450 (CYP450) enzyme system. clopidogrel 0-11 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 91-106 23549485-14 2013 CYP2C19*2 allele carriers had a higher platelet reactivity after clopidogrel loading measured by adenosine diphosphate-induced aggregation in LTA (P=0.008) and vasodilator-stimulated phosphoprotein phosphorylation (P=0.035); however, there was no difference in the inflammatory markers. clopidogrel 65-76 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 0-7 23462555-4 2013 Testing for mutations in CYP2C19, as recommended by the FDA, only correctly predicted if a patient would respond to clopidogrel 52.4% of the time. clopidogrel 116-127 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 25-32 23397280-2 2013 The shortcomings of the most commonly used P2Y12 receptor inhibitor clopidogrel-that is its delayed onset of action, its interindividual response variability, and the phenomenon of high on-treatment platelet reactivity-led to the development of more potent P2Y12 receptor inhibitors (prasugrel and ticagrelor) that proved their superiority in terms of reducing thrombotic events compared to clopidogrel. clopidogrel 68-79 purinergic receptor P2Y12 Homo sapiens 43-48 23149816-2 2013 Clopidogrel is a prodrug which requires a two-step hepatic biotransformation thanks to the cytochrome P450 (CYP450) enzyme system. clopidogrel 0-11 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 108-114 23397280-2 2013 The shortcomings of the most commonly used P2Y12 receptor inhibitor clopidogrel-that is its delayed onset of action, its interindividual response variability, and the phenomenon of high on-treatment platelet reactivity-led to the development of more potent P2Y12 receptor inhibitors (prasugrel and ticagrelor) that proved their superiority in terms of reducing thrombotic events compared to clopidogrel. clopidogrel 68-79 purinergic receptor P2Y12 Homo sapiens 257-262 23149816-3 2013 Genetic polymorphism of CYP450 system (e.g., CYP2C19*2) responsible for altered clopidogrel metabolism is a major cause of high on-treatment platelet reactivity (HTPR), which translates into thrombotic events in stented patients. clopidogrel 80-91 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 24-30 23397280-2 2013 The shortcomings of the most commonly used P2Y12 receptor inhibitor clopidogrel-that is its delayed onset of action, its interindividual response variability, and the phenomenon of high on-treatment platelet reactivity-led to the development of more potent P2Y12 receptor inhibitors (prasugrel and ticagrelor) that proved their superiority in terms of reducing thrombotic events compared to clopidogrel. clopidogrel 391-402 purinergic receptor P2Y12 Homo sapiens 43-48 23397280-2 2013 The shortcomings of the most commonly used P2Y12 receptor inhibitor clopidogrel-that is its delayed onset of action, its interindividual response variability, and the phenomenon of high on-treatment platelet reactivity-led to the development of more potent P2Y12 receptor inhibitors (prasugrel and ticagrelor) that proved their superiority in terms of reducing thrombotic events compared to clopidogrel. clopidogrel 391-402 purinergic receptor P2Y12 Homo sapiens 257-262 23397280-4 2013 Thus, it still warrants further investigation if a tailored, platelet function guided, antiplatelet therapy in ACS patients with the available P2Y12 receptor inhibitors prasugrel, ticagrelor, and clopidogrel can lead to improved patients outcome. clopidogrel 196-207 purinergic receptor P2Y12 Homo sapiens 143-148 23149816-3 2013 Genetic polymorphism of CYP450 system (e.g., CYP2C19*2) responsible for altered clopidogrel metabolism is a major cause of high on-treatment platelet reactivity (HTPR), which translates into thrombotic events in stented patients. clopidogrel 80-91 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 45-52 23435863-2 2013 Current anti-platelet treatments are mainly based on inhibition of two important pathways of platelet activation: thromboxane A2 (TXA2) mediated (aspirin) and adenosine diphosphate (ADP)-P2Y12 receptor mediated (clopidogrel, prasugrel, and ticagrelor). clopidogrel 212-223 purinergic receptor P2Y12 Homo sapiens 187-192 23543615-2 2013 However, the platelet inhibitory effect of clopidogrel, the most commonly used P2Y12 inhibitor, is variable between patients. clopidogrel 43-54 purinergic receptor P2Y12 Homo sapiens 79-84 23618682-2 2013 An underlying cause for suboptimal platelet inhibition is varying response to clopidogrel, which is linked to polymorphisms in the CYP2C19 gene responsible for the metabolism and activation of clopidogrel. clopidogrel 78-89 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 131-138 23672863-1 2013 The considerable progress in P2Y12-platelet blockers has important perioperative implications due to a family of novel agents beyond clopidogrel. clopidogrel 133-144 purinergic receptor P2Y12 Homo sapiens 29-34 23697979-2 2013 Recent evidence supports a role of loss-of-function (LOF) variants in the cytochrome P450 enzyme CYP2C19 as a determinant of clopidogrel response.

sapiens 26-31 23588782-10 2013 CYP2C19 is responsible for metabolising clopidogrel, proton pump inhibitors (PPIs) and some antidepressants. clopidogrel 40-51 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 0-7 23588782-11 2013 Carriers of CYP2C19 variant alleles exhibit a reduced capacity to produce the active metabolite of clopidogrel, and are at increased risk of adverse cardiovascular events. clopidogrel 99-110 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 12-19 23640828-6 2013 RESULTS: The difference before and after clopidogrel treatment on adenosine diphosphate-induced platelet aggregation was significantly smaller in patients carrying 1 or 2 CYP2C19 loss-of-function alleles (*2, *3) compared with patients carrying none. clopidogrel 41-52 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 171-178 23640828-8 2013 Regression analysis showed that CYP2C19 was an independent predictor of clopidogrel resistance. clopidogrel 72-83 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 32-39 23640828-9 2013 CONCLUSIONS: CYP2C19 genotypes had significant impact on clopidogrel response and prognosis of patients with stroke.

varying response to clopidogrel, which is linked to polymorphisms in the CYP2C19 gene responsible for the metabolism and activation of clopidogrel. clopidogrel 193-204 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 131-138 23618682-4 2013 Randomized controlled trials have shown that high doses of clopidogrel can overcome suboptimal platelet response in carriers of the

gain-of-function allele have been linked with response to clopidogrel, but preliminary data did not show any significant influence of these alleles on prasugrel effect. clopidogrel 119-130 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 50-57 22990067-2 2012 To address this issue, we assessed the relation of single nucleotide polymorphisms within genes modulating clopidogrel absorption

norvegicus 52-55 22975710-8 2012 Clopidogrel (10(-6)M) also inhibited EGF-stimulated EGF receptor, PERK expression, and cell proliferation in RGM-1 cells (P<0.05), and caused much less inhibition of EGF-stimulated cell proliferation in EGF receptor over-expressed RGM-1 cells than in RGM-1 cells (22% vs. 32% reduction). clopidogrel 0-11 epidermal growth factor like 1 Rattus norvegicus 52-55 22975710-8 2012 Clopidogrel (10(-6)M) also inhibited EGF-stimulated EGF receptor, PERK expression, and cell proliferation in RGM-1 cells (P<0.05), and caused much less inhibition of EGF-stimulated cell proliferation in EGF receptor over-expressed RGM-1 cells than in RGM-1 cells (22% vs. 32% reduction). clopidogrel 0-11 epidermal growth factor like 1 Rattus norvegicus 52-55 22975710-9 2012 In conclusion, clopidogrel delays gastric ulcer healing in rats via inhibiting gastric epithelial cell proliferation, at least by inhibition of the EGF receptor-ERK signal transduction pathway. clopidogrel 15-26 epidermal growth factor like 1 Rattus norvegicus 148-151 23075823-4 2012 PPIs can attenuate metabolism of clopidogrel to its active metabolite by inhibiting various hepatic CYP450

and PON1 in the mechanism of clopidogrel bioactivation and in vivo antiplatelet response. clopidogrel 66-77 paraoxonase 1 Homo sapiens 41-45 22374717-1 2012 AIMS: It is thought that clopidogrel bioactivation and antiplatelet response are related to cytochrome P450 2C19 (CYP2C19). clopidogrel 25-36 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 92-112 22374717-1 2012 AIMS: It is thought that clopidogrel bioactivation and antiplatelet response are related to cytochrome P450 2C19 (CYP2C19). clopidogrel 25-36 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 114-121 22374717-2 2012 However, a recent study challenged this notion by proposing CYP2C19 as wholly irrelevant, while identifying paraoxonase-1 (PON1) and its Q192R polymorphism as the major driver of clopidogrel bioactivation and efficacy. clopidogrel 179-190 paraoxonase 1 Homo sapiens 108-121 22374717-2 2012 However, a recent study challenged this notion by proposing CYP2C19 as wholly irrelevant, while identifying paraoxonase-1 (PON1) and its Q192R polymorphism as the major driver of clopidogrel bioactivation and efficacy. clopidogrel 179-190 paraoxonase 1 Homo sapiens 123-127 22374717-3 2012 The aim of this study was to systematically elucidate the mechanism and relative contribution of PON1 in comparison to CYP2C19 to clopidogrel bioactivation and antiplatelet response. clopidogrel 130-141 paraoxonase 1 Homo sapiens 97-101 22374717-3 2012 The aim of this study was to systematically elucidate the mechanism and relative contribution of PON1 in comparison to CYP2C19 to clopidogrel bioactivation and antiplatelet response. clopidogrel 130-141 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 119-126 22374717-8 2012 Secondly, metabolic profiling of clopidogrel in vitro confirmed the role of CYP2C19 in bioactivating clopidogrel to H4. clopidogrel 101-112 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 76-83 22374717-11 2012 CONCLUSION: Our results demonstrate that PON1 does not mediate clopidogrel active metabolite formation or antiplatelet action, while CYP2C19 activity and genotype remains a predictor of clopidogrel pharmacokinetics and antiplatelet response. clopidogrel 186-197 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 133-140 23046071-0 2012 The influence of omeprazole on platelet inhibition of clopidogrel in

(especially omeprazole) interaction are raised, because they are both metabolized by CYP2C19. clopidogrel 23-34 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 147-154 23046071-3 2012 The study was to compare the influence of omeprazole on platelet inhibition of clopidogrel in various CYP2C19 mutant alleles. clopidogrel 79-90 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 102-109 23046071-11 2012 In conclusion, concomitant therapy with omeprazole appears to reduce the antiplatelet effect of clopidogrel most significantly in homEMs of CYP2C19. clopidogrel 96-107 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 140-147 22965108-0 2012 Comparison of prasugrel and clopidogrel in the setting of ACS without revascularization. clopidogrel 28-39 1-aminocyclopropane-1-carboxylate synthase homolog (inactive) Homo sapiens 58-61 22797934-1 2012 Clopidogrel is a prodrug that undergoes bioconversion via cytochrome P450 system to form an active

measuring the aggregatory response to 5 muM ADP by light transmission aggregation (LTA) or multiple electrode aggregometry (MEA) or by the vasodilator-stimulated phosphoprotein platelet reactivity index (VASP-PRI). clopidogrel 27-38 vasodilator stimulated phosphoprotein Homo sapiens 267-271 22855283-4 2012 The pre- and post-PCI corrected thrombolysis in myocardial infarction frame count (CTFC) and the 8-h post-treatment platelet vasodilator-stimulated phosphoprotein (VASP) index was compared with a matched historical Asian STEMI cohort (n = 65) receiving 600 mg of clopidogrel pretreatment.

member 13) was present in 80% and antibodies to 100% of these TTP patients on ticlopidine, 0% of the patients with clopidogrel-associated TTP (p < 0.05), and an unknown percentage of patients with prasugrel-associated TTP. clopidogrel 219-230 ADAM metallopeptidase with thrombospondin type 1 motif 13 Homo sapiens 21-30 22782352-0 2012 Effects of pioglitazone on platelet P2Y12-mediated signalling in clopidogrel-treated patients with type 2 diabetes mellitus. clopidogrel 65-76 purinergic receptor P2Y12 Homo sapiens 36-41 22974536-1 2012 BACKGROUND: A recent clinical trial has demonstrated that patients with acute coronary syndromes (ACS) and the reduced function allele CYP2C19*2 (*2 allele), who are treated with thienopyridines, have an increased risk of adverse cardiac events with clopidogrel, but not with prasugrel. clopidogrel 250-261 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 135-142 23363669-10 2012 (3) Multivariate logistic regression analysis showed that history of renal failure (OR = 19.77, 95%CI 4.38 - 89.18, P < 0.01) and clopidogrel (OR = 19.77, 95%CI 4.38 - 89.18, P < 0.01) and GPIIb/IIIa receptor antagonist (OR = 343.57, 95%CI 40.39 - 999.99, P < 0.01) use were the independent risk factors for bleeding. clopidogrel 133-144 integrin subunit alpha 2b Homo sapiens 195-200 23363670-1 2012 OBJECTIVE: To detect the single nucleotide polymorphisms of clopidogrel metabolism related genes (CYP2C19, ABCB1 and PON1) in Chinese patients with acute coronary syndrome (ACS) by genotype analysis. clopidogrel 60-71 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 98-105 23363670-1 2012 OBJECTIVE: To detect the single nucleotide polymorphisms of clopidogrel metabolism related genes (CYP2C19, ABCB1 and PON1) in Chinese patients with acute coronary syndrome (ACS) by genotype analysis. clopidogrel 60-71 ATP binding cassette subfamily B member 1 Homo sapiens 107-112 23363670-1 2012 OBJECTIVE: To detect the single nucleotide polymorphisms of clopidogrel metabolism related genes (CYP2C19, ABCB1 and PON1) in Chinese patients with acute coronary syndrome (ACS) by genotype analysis. clopidogrel 60-71 paraoxonase 1 Homo sapiens 117-121 23139136-1 2012 In this study, we investigated pharmacokinetic drug interactions of clopidogrel with P-gp inhibitors in rats and dogs. clopidogrel 68-79 phosphoglycolate phosphatase Rattus norvegicus 85-89 22234956-3 2012 PPIs are reported to diminish the effect of clopidogrel because both are metabolized by CYP2C19. clopidogrel 44-55 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 88-95 22782352-1 2012 Patients with type 2 diabetes mellitus (T2DM) have impaired clopidogrel-induced antiplatelet effects, which may be in part attributed to their reduced sensitivity to insulin and consequently, results in upregulation of the P2Y12 signalling pathway. clopidogrel 60-71 purinergic receptor P2Y12 Homo sapiens 223-228 22782352-2 2012 It has been hypothesised that insulin sensitising strategies may enhance clopidogrel-mediated P2Y12 inhibitory effects. clopidogrel 73-84 purinergic receptor P2Y12 Homo sapiens 94-99 22782352-3 2012 The aim of this pilot pharmacodynamics (PD) study was to assess the impact of pioglitazone on clopidogrel-mediated P2Y12 inhibitory effects in patients with T2DM. clopidogrel 94-105 purinergic receptor P2Y12 Homo sapiens 115-120 22996695-10 2012 Finally, mice treated with the clinical inhibitor of P2RY12, clopidogrel, were protected from pathologic osteolysis. clopidogrel 61-72 purinergic receptor P2Y, G-protein coupled 12 Mus musculus 53-59 22372976-1 2012 OBJECTIVES: The P2Y(12) inhibitor clopidogrel inhibits platelet aggregation and is used in the treatment and prevention of coronary artery disease. clopidogrel 34-45 purinergic receptor P2Y12 Homo sapiens 16-23 22372976-9 2012 CONCLUSIONS: Use of the P2Y(12) inhibitor clopidogrel is associated with risk of fractures. clopidogrel 42-53 purinergic receptor P2Y12 Homo sapiens 24-31 23026663-2 2012 Treatment regimens using the newer CYP12 antagonists prasugrel and ticagrelor demonstrate improved ex-vivo platelet inhibition and superior clinical efficacy in large-scale clinical trials-even in patients demonstrating clopidogrel resistance. clopidogrel 220-231 cytochrome P450 family 8 subfamily B member 1 Homo sapiens 35-40 23048056-11 2012 Genotyping showed the same efficacy between high-dose clopidogrel and prasugrel in the 18 (56.3%) CYP2C19*2 noncarriers (HTPR in 12.5% versus 0, P=0.274), whereas it was significantly worse in the 14 (43.7%) carriers (HTPR in 43.7% versus 0, P=0.003). clopidogrel 54-65 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 98-105 23048056-13 2012 Conversely, high-dose clopidogrel can address HTPR only in CYP2C19*2 noncarriers. clopidogrel 22-33 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 59-66 22989428-0 2012 Clinical significance of the clopidogrel-proton pump inhibitor interaction after peripheral endovascular intervention for claudication. clopidogrel 29-40 ATPase H+/K+ transporting subunit alpha Homo sapiens 41-52 22989428-1 2012 OBJECTIVE: Despite numerous studies in the cardiology literature, the clinical impact of proton pump inhibitor (PPI) administration on the antiplatelet effect of clopidogrel remains controversial. clopidogrel 162-173 ATPase H+/K+ transporting subunit alpha Homo sapiens 89-100 22651985-8 2012 Pre-incubation with recombinant human CYP3A4 not only caused degradation of clopidogrel and ticlopidine, but also increased cytotoxicity. clopidogrel 76-87 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 38-44 22651985-10 2012 Pre-incubation with freshly isolated human granulocytes was not only associated with a myeloperoxidase-dependent degradation of clopidogrel, clopidogrel carboxylate and ticlopidine, but also with dose-dependent cytotoxicity of these compounds starting at 10 muM. clopidogrel 128-139 myeloperoxidase Homo sapiens 87-102 22651985-12 2012 Taking exposure data in humans into account, the myelotoxic element of clopidogrel therapy is likely to be secondary to the formation of metabolites from clopidogrel carboxylate by myeloperoxidase. clopidogrel 71-82 myeloperoxidase Homo sapiens 181-196 24175073-5 2012 HPR and CYP2C19 LoF carriage are associated with clinical outcomes in high-risk clopidogrel-treated patients who have undergone percutaneous coronary intervention (PCI). clopidogrel 80-91 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 8-15 22450429-2 2012 Both loss- and gain-of-function single nucleotide variants of CYP2C19 genes have been identified that affect clopidogrel metabolism and anti-platelet response. clopidogrel 109-120 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 62-69 24900388-0 2012 Identification of the Significant Involvement and Mechanistic Role of CYP3A4/5 in Clopidogrel Bioactivation. clopidogrel 82-93 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 70-76 24900388-2 2012 Previous studies have suggested that genetic polymorphism of CYP2C19 might be one determinant of clopidogrel efficacy and led to the CYP2C19 genotype-tailored antithrombotic therapy. clopidogrel 97-108 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 61-68 24900388-7 2012 Identifying the significant involvement of CYP3A4/5 and characterizing its mechanistic role in clopidogrel bioactivation might assist future pharmacogenomic studies in exploring the full mechanism underlying clopidogrel efficacy. clopidogrel 208-219 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 43-49 22338575-3 2012 According to the present guidelines, a dual antiplatelet treatment regimen consisting of aspirin and a P2Y12 receptor inhibitor such as clopidogrel, prasugrel or ticagrelor is routinely administered to ACS patients and to patients undergoing PCI in order to prevent thrombotic vessel occlusions. clopidogrel 136-147 purinergic receptor P2Y12 Homo sapiens 103-108 22338575-5 2012 Along with this development, more potent P2Y12 receptor inhibitors like prasugrel and ticagrelor are substitutes for clopidogrel in specific circumstances such as in ACS patients or in patients who do not adequately respond to standard clopidogrel treatment. clopidogrel 236-247 purinergic receptor P2Y12 Homo sapiens 41-46 22450429-13 2012 Although several prior studies, including mainly stented patients, have emphasized the relationship between CYP2C19 loss-of-function alleles and efficacy of clopidogrel, this study of stable patients establishes a potential link with reduced bleeding complications. clopidogrel 157-168 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 108-115 22507978-1 2012 AIMS: CYP3A4-metabolized statins can influence the pharmacodynamic effect of clopidogrel. clopidogrel 77-88 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 6-12 22507978-12 2012 CONCLUSIONS: Among PCI-treated patients with HPR during co-administration of clopidogrel and atorvastatin, switching to a non-CYP3A4-metabolized statin can significantly decrease platelet reactivity and the prevalence of HPR. clopidogrel 77-88 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 126-132 22569995-6 2012 The median peri-interventional concentration of beta-TG was

pharmacologically active metabolite of clopidogrel from its GSH conjugate. clopidogrel 88-99 glutaredoxin Homo sapiens 0-12 22733806-12 2012 In conclusion, we found that human glutaredoxin is a main contributor to the formation of the pharmacologically active metabolite of clopidogrel from its GSH conjugate in human liver. clopidogrel 133-144 glutaredoxin Homo sapiens 35-47 22744772-10 2012 The

cytochrome P450 family 2 subfamily C member 19 Homo sapiens 50-57 22293861-4 2012 Studies have shown that patients possessing genetic variants of the CYP2C19 isozyme may be at increased risk of adverse cardiovascular events due to impaired clopidogrel efficacy, although this has not been definitively demonstrated. clopidogrel 158-169 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 68-75 22440495-2 2012 BACKGROUND: Cigarette smoking is an inducer of cytochrome P450 1A2, a hepatic enzyme involved in clopidogrel metabolism. clopidogrel 97-108 cytochrome P450 family 1 subfamily A member 2 Homo sapiens 47-66 22448399-9 2012 Clopidogrel was discontinued a median of 6 days before surgery and 2 days prior to initiating GP IIb/IIIa inhibitor. clopidogrel 0-11 integrin subunit alpha 2b Homo sapiens 94-100 22448399-13 2012 CONCLUSIONS: In patients with DES, who require cessation of clopidogrel before surgery, bridging with GP IIb/IIIa inhibitors appears effective in preventing adverse cardiac outcomes but may be associated with bleeding in patients undergoing cardiac surgery. clopidogrel 60-71 integrin subunit alpha 2b Homo sapiens 102-108 21834799-1 2012 BACKGROUND: The CYP3A4 inhibition by calcium channel blockers (CCBs) may attenuate the effectiveness of clopidogrel. clopidogrel 104-115 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 16-22 22116003-1 2012 INTRODUCTION AND OBJECTIVES: CYP2C19*2 and CYP2C19*17 alleles appear to contribute to heterogeneous clopidogrel metabolism. clopidogrel 100-111 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 29-36 22116003-1 2012 INTRODUCTION AND OBJECTIVES: CYP2C19*2 and CYP2C19*17 alleles appear to contribute to heterogeneous clopidogrel metabolism. clopidogrel 100-111 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 43-50 22116003-8 2012 CONCLUSIONS: Even though CYP2C19 genotype is associated with variable on-clopidogrel platelet reactivity, it has no significant clinical influence. clopidogrel 73-84 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 25-32 22613391-3 2012 A total of 1021 patients were enrolled, with 178 of them prescribed clopidogrel and 843 patients were administrated clopidogrel combined with statins (CYP3A4-metabolized statins 636 and non CYP3A4-metabolized statins 207). clopidogrel 116-127 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 151-157 22103858-6 2012 (Bouman et al., (2011) 17, 110) reported that the second step of clopidogrel bioactivation was not catalyzed by P450 enzymes but by paraoxonase-1(PON-1) and that PON-1 was a major determinant of clopidogrel efficacy. clopidogrel 65-76 paraoxonase 1 Homo sapiens 132-145 22103858-6 2012 (Bouman et al., (2011) 17, 110) reported that the second step of clopidogrel bioactivation was not catalyzed by P450 enzymes but by paraoxonase-1(PON-1) and that PON-1 was a major determinant of clopidogrel efficacy. clopidogrel 65-76 paraoxonase 1 Homo sapiens 146-151 22040781-0 2012 Increased clopidogrel response is associated with ABCC3 expression: a pilot study. clopidogrel 10-21 ATP binding cassette subfamily C member 3 Homo sapiens 50-55 22040781-1 2012 BACKGROUND: The aim of this study was investigate the relationship between ABCB1 and ABCC3 gene expressions in peripheral blood cells (PBC) and the response to clopidogrel in patients with coronary arterial disease (CAD). clopidogrel 160-171 ATP binding cassette subfamily B member 1 Homo sapiens 75-80 22040781-1 2012 BACKGROUND: The aim of this study was investigate the relationship between ABCB1 and ABCC3 gene expressions in peripheral blood cells (PBC) and the response to clopidogrel in patients with coronary arterial disease (CAD). clopidogrel 160-171 ATP binding cassette subfamily C member 3 Homo sapiens 85-90 22040781-9 2012 Moreover, CAD patients with low ABCC3 expression (Qe1, <2.5x10(-3)) had higher probability to have a good response to clopidogrel (OR: 18.00, 95%CI: 1.90-169.99, p=0.001). clopidogrel 121-132 ATP binding cassette subfamily C member 3 Homo sapiens 32-37 22040781-12 2012 CONCLUSIONS: Low ABCC3 mRNA expression in peripheral blood cells is associated with increased clopidogrel response, but further studies are needed to describe the functional relationship of clopidogrel with the ABCC3. clopidogrel 94-105 ATP binding cassette subfamily C member 3 Homo sapiens 17-22 22040781-12 2012 CONCLUSIONS: Low ABCC3 mRNA expression in peripheral blood cells is associated with increased clopidogrel response, but further studies are needed to describe the functional relationship of clopidogrel with the ABCC3. clopidogrel 190-201 ATP binding cassette subfamily C member 3 Homo sapiens 17-22 22040781-12 2012 CONCLUSIONS: Low ABCC3 mRNA expression in peripheral blood cells is associated with increased clopidogrel response, but further studies are needed to describe the functional relationship of clopidogrel with the ABCC3. clopidogrel 190-201 ATP binding cassette subfamily C member 3 Homo sapiens 211-216 21602258-3 2012 The plasma levels of CRP, P-selectin, sCD40L, IL-6 was higher in 65 (18.5%) patients with clopidogrel resistance than in those with normal responsiveness at 6 months after PCI. clopidogrel 90-101 C-reactive protein Homo sapiens 21-24 22103858-6 2012 (Bouman et al., (2011) 17, 110) reported that the second step of clopidogrel bioactivation was not catalyzed by P450 enzymes but by paraoxonase-1(PON-1) and that PON-1 was a major determinant of clopidogrel efficacy. clopidogrel 65-76 paraoxonase 1 Homo sapiens 162-167 22103858-6 2012 (Bouman et al., (2011) 17, 110) reported that the second step of clopidogrel bioactivation was not catalyzed by P450 enzymes but by paraoxonase-1(PON-1) and that PON-1 was a major determinant of clopidogrel efficacy. clopidogrel 195-206 paraoxonase 1 Homo sapiens 146-151 22103858-6 2012 (Bouman et al., (2011) 17, 110) reported that the second step of clopidogrel bioactivation was not catalyzed by P450 enzymes but by paraoxonase-1(PON-1) and that PON-1 was a major determinant of clopidogrel efficacy. clopidogrel 195-206 paraoxonase 1 Homo sapiens 162-167 22186965-2 2012 The measurement of vasodilator-associated stimulated phosphoprotein (VASP) phosphorylation, expressed as platelet reactivity index (PRI), mirrors the degree of P2Y(12) receptor inhibition and can detect the well-known variable response to clopidogrel. clopidogrel 239-250 vasodilator stimulated phosphoprotein Homo sapiens 19-67 22186965-2 2012 The measurement of vasodilator-associated stimulated phosphoprotein (VASP) phosphorylation, expressed as platelet reactivity index (PRI), mirrors the degree of P2Y(12) receptor inhibition and can detect the well-known

clopidogrel in patients undergoing percutaneous coronary intervention. clopidogrel 68-79 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 0-7 21831410-7 2012 CONCLUSIONS: Apart from the CYP2C19*2, other genetic variants involved in clopidogrel metabolism and action like CYP2B6*5 and P2RY12 seem to have an important association with HTPR. clopidogrel 74-85 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 113-119 21831410-7 2012 CONCLUSIONS: Apart from the CYP2C19*2, other genetic variants involved in clopidogrel metabolism and action like CYP2B6*5 and P2RY12 seem to have an important association with HTPR. clopidogrel 74-85 purinergic receptor P2Y12 Homo sapiens 126-132 22298798-1 2012 BACKGROUND: The prodrug clopidogrel requires intestinal absorption by the efflux pump P-glycoprotein MDR1 (multidrug resistant-1), encoded by the ABCB1 gene. clopidogrel 24-35 ATP binding cassette subfamily B member 1 Homo sapiens 101-105 22298798-1 2012 BACKGROUND: The prodrug clopidogrel requires intestinal absorption by the efflux pump P-glycoprotein MDR1 (multidrug resistant-1), encoded by the ABCB1 gene. clopidogrel 24-35 ATP binding cassette subfamily B member 1 Homo sapiens 107-128 22298798-1 2012 BACKGROUND: The prodrug clopidogrel requires intestinal absorption by the efflux pump P-glycoprotein MDR1 (multidrug resistant-1), encoded by the ABCB1 gene. clopidogrel 24-35 ATP binding cassette subfamily B member 1 Homo sapiens 146-151 22298798-2 2012 Prior studies suggested that a common and functional genetic variant (C3435T, rs1045642) within ABCB1 influences clopidogrel treatment efficacy; however, existing data are highly inconsistent, because other studies failed to replicate this postulated association. clopidogrel 113-124 ATP binding cassette subfamily B member 1 Homo sapiens 96-101 22298798-3 2012 Thus, the aim of this study was to assess the association of ABCB1 C3435T genotypes with the antiplatelet efficacy of clopidogrel and the risk of stent thrombosis (ST) in large cohorts of clopidogrel-treated patients undergoing percutaneous coronary intervention. clopidogrel 118-129 ATP binding cassette subfamily B member 1 Homo sapiens 61-66 22319066-2 2012 BACKGROUND: Clopidogrel is an inactive prodrug; it is converted to its active metabolite through the cytochrome P450 (CYP3A4) pathway, which also metabolizes calcium channel blockers (CCBs). clopidogrel 12-23 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 118-124 22190063-1 2012 Variants in ABCB1 and CYP2C19 have been identified as predictors of cardiac events during clopidogrel therapy initiated after myocardial infarction (MI) or percutaneous coronary intervention (PCI). clopidogrel 90-101 ATP binding cassette subfamily B member 1 Homo sapiens 12-17 22190063-1 2012 Variants in ABCB1 and CYP2C19 have been identified as predictors of cardiac events during clopidogrel therapy initiated after myocardial infarction (MI) or percutaneous coronary intervention (PCI). clopidogrel 90-101 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 22-29 22190063-6 2012 In this population, genetic signals for clopidogrel resistance in ABCB1 and CYP2C19 were replicated, supporting the use of EHRs for pharmacogenomic studies. clopidogrel 40-51 ATP binding cassette subfamily B member 1 Homo sapiens 66-71 22190063-6 2012 In this population, genetic signals for clopidogrel resistance in ABCB1 and CYP2C19 were replicated, supporting the use of EHRs for pharmacogenomic studies. clopidogrel 40-51 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 76-83 22261685-2 2012 As described in this issue, Delaney and co-workers validated the use of EHRs by demonstrating that loss-of-function CYP2C19*2 was associated with poorer cardiovascular outcomes in clopidogrel-treated patients with an effect size similar to that reported in more controlled clinical trials. clopidogrel 180-191 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 116-123 22090195-4 2012 These warnings were largely based on in-vitro studies and observational analyses suggesting decreased efficacy of clopidogrel in the presence of proton pump inhibitors. clopidogrel 114-125 ATPase H+/K+ transporting subunit alpha Homo sapiens 145-156 22204719-0 2012 Effects of proton pump inhibitors on platelet function in patients receiving clopidogrel: a systematic review. clopidogrel 77-88 ATPase H+/K+ transporting subunit alpha Homo sapiens 11-22 22204719-1 2012 BACKGROUND: There is considerable debate regarding the negative impact of concomitant proton pump inhibitor (PPI) therapy on the antiplatelet efficacy of clopidogrel. clopidogrel 154-165 ATPase H+/K+ transporting subunit alpha Homo sapiens 86-97 21895760-2 2012 Newly developed P2Y12 inhibitors are more potent, more predictable, and have a faster onset of action than clopidogrel, characteristics that make them particularly attractive for high-risk percutaneous coronary intervention (PCI). clopidogrel 107-118 purinergic receptor P2Y12 Homo sapiens 16-21 21895760-7 2012 Both prasugrel and ticagrelor, opposed to clopidogrel, have shown that stronger P2Y12 inhibition led respectively to significant 19 and 16% relative risk reduction of a similar primary end point combining cardiovascular death, non-fatal myocardial infarction, or non-fatal stroke. clopidogrel 42-53 purinergic receptor P2Y12 Homo sapiens 80-85 21895760-10 2012 On the other hand, these newly developed P2Y12 inhibitors decrease mortality after PCI compared with clopidogrel. clopidogrel 101-112 purinergic receptor P2Y12 Homo sapiens 41-46 21895761-8 2012 The enzymatic generation of the active metabolite of prasugrel is much more effective than that of clopidogrel where only about 5% of oral clopidogrel is transformed into the active compound by two-step CYP-dependent procedures. clopidogrel 99-110 peptidylprolyl isomerase G Homo sapiens 203-206 21895761-8 2012 The enzymatic generation of the active metabolite of prasugrel is much more effective than that of clopidogrel where only about 5% of oral clopidogrel is transformed into the active compound by two-step CYP-dependent procedures. clopidogrel 139-150 peptidylprolyl isomerase G Homo sapiens 203-206 22142030-9 2012 However, there is a subset of patients who have reduced conversion of clopidogrel to its active metabolites due to genetic polymorphism of hepatic P-450 (carriers of CYP2C19 loss-of-function alleles). clopidogrel 70-81 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 166-173 22123356-0 2012 The gain-of-function variant allele CYP2C19*17: a double-edged sword between thrombosis and bleeding in clopidogrel-treated patients. clopidogrel 104-115 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 36-43 22123356-1 2012 BACKGROUND: A large number of clinical studies have documented that a loss-of-function variant CYP2C19*2 affects clinical profiles of clopidogrel (efficacy and safety). clopidogrel 134-145 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 95-102 22123356-3 2012 OBJECTIVES: To systematically summarize all available clinical data assessing the role of the CYP2C19*17 variant in patients taking clopidogrel. clopidogrel 132-143 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 94-101 22123356-8 2012 Moreover, the presence of the CYP2C19*17 variant might lead to increased response to clopidogrel, as shown by a marked lower prevalence of HPR in carriers than in non-carriers (37.9% vs. 50.8%; OR, 0.60; 95% CI, 0.45-0.79; P = 0.0003; three studies). clopidogrel 85-96 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 30-37 22123356-9 2012 CONCLUSIONS: Carriers of the CYP2C19*17 variant have greater therapeutic responsiveness to clopidogrel than non-carriers, but they have an increased risk of developing bleeding as well. clopidogrel 91-102 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 29-36 21602258-3 2012 The plasma levels of CRP, P-selectin, sCD40L, IL-6 was higher in 65 (18.5%) patients with clopidogrel resistance than in those with normal responsiveness at 6 months after PCI. clopidogrel 90-101 selectin P Homo sapiens 26-36 21602258-3 2012 The plasma levels of CRP, P-selectin, sCD40L, IL-6 was higher in 65 (18.5%) patients with clopidogrel resistance than in those with normal responsiveness at 6 months after PCI. clopidogrel 90-101 interleukin 6 Homo sapiens 46-50 21689142-0 2012 Pharmacokinetics and pharmacodynamics following maintenance doses of prasugrel and clopidogrel in Chinese carriers of CYP2C19 variants. clopidogrel 83-94 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 118-125 21689142-8 2012 CONCLUSIONS: Prasugrel demonstrated higher active metabolite exposure and more consistent pharmacodynamic response across all three predicted phenotype groups compared with clopidogrel, confirming observations from previous research that CYP2C19 phenotype plays an important role in variability of response to clopidogrel, but has no impact on response to prasugrel. clopidogrel 173-184 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 238-245 21689142-8 2012 CONCLUSIONS: Prasugrel demonstrated higher active metabolite exposure and more consistent pharmacodynamic response across all three predicted phenotype groups compared with clopidogrel, confirming observations from previous research that CYP2C19 phenotype plays an important role in variability of response to clopidogrel, but has no impact on response to prasugrel. clopidogrel 310-321 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 238-245 22785462-1 2012 BACKGROUND: Cytochrome P450 (CYP) 2C19 polymorphism is associated with reduced responsiveness to clopidogrel and poor clinical outcome after drug-eluting stent (DES) implantation, but its contribution to lesion outcome after DES implantation is unclear. clopidogrel 98-109 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 13-39 22030270-0 2012 CYP2C19 gene variants cut-off levels for on-clopidogrel platelet aggregation. clopidogrel 44-55 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 0-7 22906899-3 2012 P2Y(12) inhibitors include ticlopidine (now rarely used), clopidogrel, prasugrel, and ticagrelor. clopidogrel 58-69 purinergic receptor P2Y12 Homo sapiens 0-7 22906906-2 2012 Candidate gene and genome-wide association studies have found that common genetic polymorphisms of the cytochrome P450 (CYP) 2C19 isoenzyme that result in a loss of functional activity are associated with less exposure of clopidogrel active metabolite and a diminished antiplatelet effect. clopidogrel 222-233 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 103-129 22971905-0 2012 Association of CYP2C19 genotype with periprocedural myocardial infarction after uneventful stent implantation in Chinese patients receiving clopidogrel pretreatment. clopidogrel 140-151 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 15-22 22427735-0 2012 Influence of paraoxonase-1 Q192R and cytochrome P450 2C19 polymorphisms on clopidogrel response. clopidogrel 75-86 paraoxonase 1 Homo sapiens 13-26 22427735-0 2012 Influence of paraoxonase-1 Q192R and cytochrome P450 2C19 polymorphisms on clopidogrel response. clopidogrel 75-86 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 37-57 22427735-3 2012 Conflicting results have been reported in regard to (1) the association of a common polymorphism of PON1 (Q192R) with reduced rates of coronary stent thrombosis in patients taking clopidogrel and (2) its effects on platelet inhibition in patient populations of European descent. clopidogrel 180-191 paraoxonase 1 Homo sapiens 100-104 22427735-10 2012 CONCLUSION: CYP2C19*2 allele is associated with impaired platelet inhibition by clopidogrel and high on-treatment platelet aggregation. clopidogrel 80-91 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 12-19 22724417-5 2012 Pharmacogenomic analyses have identified loss-of-function variant alleles of CYP 2C19 and specifically the 2C19*2 allele, to be the predominant genetic mediators of the antiplatelet effect of clopidogrel. clopidogrel 192-203 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 77-85 22360514-2 2012 Ticlopidine, Clopidogrel, Prasugrel, Ticagrelor, Cangrelor and Elinogrel are the P2Y12 inhibitors that act as antiplatelet drugs. clopidogrel 13-24 purinergic receptor P2Y12 Homo sapiens 81-86 22004687-0 2012 Effects of omeprazole and

CYP2C19 contribution to the active metabolite formation was determined from exposure of the active metabolite in two clinical studies (one phase I study with well balanced genetic polymorphic populations and a meta-analysis with a total of 396 healthy volunteers) at different clopidogrel doses. clopidogrel 303-314 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 26-33 22153531-0

cassette subfamily B member 1 Homo sapiens 99-104 22739809-8 2012 The new ESC guidelines on the management of ACS without ST segment elevation recommend the use of clopidogrel only when a new antiplatelet drug, e.g. ticagrelor or prasugrel is not available or contraindicated. clopidogrel 98-109 1-aminocyclopropane-1-carboxylate synthase homolog (inactive) Homo sapiens 44-47 22792485-1 2012 This study aimed to assess if proton pump inhibitors (PPIs) may reduce the effectiveness of clopidogrel, than H2 antagonist (anti-H2) in order to determine rehospitalization for acute coronary syndrome (re-ACS), target vessel revascularization (TVR) and cardiac death. clopidogrel 92-103 1-aminocyclopropane-1-carboxylate synthase homolog (inactive) Homo sapiens 206-209 22472213-2 2012 Clopidogrel is a prodrug and changed into active metabolite by cytochrome p450 enzymes (CYPs), especially CYP2C19. clopidogrel 0-11 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 106-113 22169056-7 2012 It was further demonstrated that the derivatizing agent (MPB) does not affect clopidogrel levels, thus from one aliquot of blood drawn clinically, this method can simultaneously quantify both clopidogrel and CAMD with sensitivity in the picogram per mL range. clopidogrel 192-203 AFA1 Homo sapiens 57-60 22623230-3 2012 AIM: To investigate whether omega-3 PUFA are able to modify platelet responsiveness to clopidogrel therapy in patients with CYP2C19 loss-of-function polymorphism undergoing percutaneous coronary intervention (PCI). clopidogrel 87-98 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 124-131 22623230-12 2012 CONCLUSIONS: The addition of omega-3 ethyl esters significantly potentiates platelet response to clopidogrel after PCI mostly in patients with CYP2C19 loss-of-function polymorphism. clopidogrel 97-108 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 143-150 23098546-2 2012 Mechanism of action of clopidogrel and main

carrier family 35 member G1 Homo sapiens 17-21 21706290-5 2011 Polymorphisms of genes encoding the cytochrome enzymes and P-glycoprotein involved in clopidogrel absorption are regarded as major

studies have identified a link between CYP2C19*2 carriers and decreased clopidogrel responsiveness as assessed by platelet reactivity testing and clinical outcomes. clopidogrel 80-91 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 47-54 21822146-2 2011 We hypothesized that formation of thienopyridine-derived nitrosothiols (ticlopidine-SNO, clopidogrel-SNO, and prasugrel-SNO) occurs directly from the respective parent drug. clopidogrel 89-100 strawberry notch homolog 1 Homo sapiens 101-104 21822146-2 2011 We hypothesized that formation of thienopyridine-derived nitrosothiols (ticlopidine-SNO, clopidogrel-SNO, and prasugrel-SNO) occurs directly from the respective parent drug. clopidogrel 89-100 strawberry notch homolog 1 Homo sapiens 101-104 21828263-6 2011 These studies show that, in vitro, CYP3A4/5, 2C19, and 2B6 are individually capable of converting clopidogrel and prasugrel to the AM and that the cytochrome P450 preference for these two thienopyridines is very similar. clopidogrel 98-109 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 35-49 21153923-3 2011 In this regard, the present study focused on the genotype profile of Southern Iranians in

273-284 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 229-236 21862689-0 2011 Mechanism-based inactivation of human cytochrome P450 2B6 by clopidogrel: involvement of both covalent modification of cysteinyl residue 475 and loss of heme. clopidogrel 61-72 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 38-57 21862689-1 2011 We have investigated the mechanisms by which clopidogrel inactivates human cytochrome P450 2B6 (CYP2B6) in a reconstituted system. clopidogrel 45-56 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 75-94 21862689-1 2011 We have investigated the mechanisms by which clopidogrel inactivates human cytochrome P450 2B6 (CYP2B6) in a reconstituted system. clopidogrel 45-56 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 96-102 21862689-2 2011 It was found that clopidogrel and its thiolactone metabolite, 2-oxo-clopidogrel, both inactivate CYP2B6 in a time- and concentration-dependent manner. clopidogrel 18-29 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 97-103 21862689-3 2011 On the basis of k(inact)/K(I) ratios, clopidogrel is approximately 5 times more efficient than 2-oxo-clopidogrel in inactivating CYP2B6. clopidogrel 38-49 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 129-135 21862689-4 2011 Analysis of the molecular mass of the CYP2B6 wild-type (WT) protein that had been inactivated by either clopidogrel or 2-oxo-clopidogrel showed an increase in the mass of the protein by ~350 Da. clopidogrel 104-115 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 38-44 21862689-5 2011 This increase in the protein mass corresponds to the addition of the active metabolite of clopidogrel to CYP2B6. clopidogrel 90-101 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 105-111 21862689-10 2011 Furthermore, inactivation of both CYP2B6 WT and C475S by clopidogrel, but not by 2-oxo-clopidogrel, led to the loss of the heme, which accounts for most of the loss of the catalytic activity. clopidogrel 57-68 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 34-40 21862689-11 2011 Collectively, these results suggest that clopidogrel inactivates CYP2B6 primarily through destruction of the heme, whereas 2-oxo-clopidogrel inactivates CYP2B6 through covalent modification of Cys475. clopidogrel 41-52 cytochrome P450 family 2 subfamily B member 6

22088980-10 2011 Clopidogrel, 225 mg daily, reduced platelet reactivity in CYP2C19*2 heterozygotes to levels achieved with standard clopidogrel, 75 mg, in noncarriers (mean ratios of platelet reactivity, VASP PRI, 0.92; 90% CI, 0.85-0.99, and PRU, 0.94; 90% CI, 0.84-1.04). clopidogrel 0-11 vasodilator stimulated phosphoprotein Homo sapiens 187-191 22088980-11 2011 In CYP2C19*2 homozygotes,

sapiens 3-10 22088980-11 2011 In CYP2C19*2 homozygotes, even with 300 mg daily of clopidogrel, mean VASP PRI was 68.3% (95% CI, 44.9%-91.6%) and mean PRU, 287.0 (95% CI, 170.2-403.8). clopidogrel 52-63 vasodilator stimulated phosphoprotein Homo sapiens 70-74 22088980-12 2011 CONCLUSION: Among patients with stable cardiovascular disease, tripling the maintenance dose of clopidogrel to 225 mg daily in CYP2C19*2 heterozygotes achieved levels of platelet reactivity similar to that seen with the standard 75-mg dose in noncarriers; in contrast, for CYP2C19*2 homozygotes, doses as high as 300 mg daily did not result in comparable degrees of platelet inhibition. clopidogrel 96-107 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 127-134 22088980-12 2011 CONCLUSION: Among patients with stable cardiovascular disease, tripling the maintenance dose of clopidogrel to 225 mg daily in CYP2C19*2 heterozygotes achieved levels of platelet reactivity similar to that seen with the standard 75-mg dose in noncarriers; in contrast, for CYP2C19*2 homozygotes, doses as high as 300 mg daily did not result in comparable degrees of platelet inhibition. clopidogrel 96-107 cytochrome

clopidogrel 43-54 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 94-101 21352268-3 2011 There is a growing body of literature showing that carriers of variant CYP2C19 alleles have impaired ability to metabolize clopidogrel (i.e. poor metabolizers), which is associated with decreased inhibition of platelet aggregation and increased cardiovascular risk. clopidogrel 123-134 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 71-78 21352268-4 2011 Some proton pump inhibitors are also metabolized by the CYP2C19 enzyme and often given together with clopidogrel to reduce gastrointestinal side effects. clopidogrel 101-112 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 56-63 21352268-5 2011 In particular, omeprazole has been shown to inhibit the

2011 A common functional variant in paraoxonase 1 (PON1), Q192R, was recently reported to be a major determinant of clopidogrel response. clopidogrel 111-122 paraoxonase 1 Homo sapiens 46-50 21900887-2 2011 The absorption of clopidogrel is regulated by multidrug-resistance protein 1 (MDR1) in the intestinal epithelium. clopidogrel 18-29 ATP binding cassette subfamily B member 1 Homo sapiens 46-76 21900887-2 2011 The absorption of clopidogrel is regulated by multidrug-resistance protein 1 (MDR1) in the intestinal epithelium. clopidogrel 18-29 ATP binding cassette subfamily B member 1 Homo sapiens 78-82 21900887-3 2011 Given that aspirin induces MDR1 in cancer cells and peripheral blood cells, it may induce MDR1 in intestinal epithelial cells as well, thereby affecting the absorption of clopidogrel. clopidogrel 171-182 ATP binding cassette subfamily B member 1 Homo sapiens 90-94 21900887-5 2011 Along with the upregulation of MDR1 proteins by aspirin, clopidogrel

subfamily F member 3 Homo sapiens 31-34 21933840-4 2011 The exact mechanism of these observations is not yet fully understood, but appears to be related to reduced concentrations of circulating

Homo sapiens 200-207 22001104-7 2011 RESULTS: Clopidogrel decreased MCP-1 expression in the carotid artery at 4 weeks after irradiation. clopidogrel 9-20 mast cell protease 1 Mus musculus 31-36 21592545-3 2011 Pharmacogenomic analyses, including candidate-gene and genome-wide association studies, have confirmed that genetic polymorphisms in the hepatic cytochrome P450 (CYP) 2C19 dominantly affect the antiplatelet effects of clopidogrel. clopidogrel 218-229 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 145-171 21592545-4 2011 CYP2C19 reduced-function alleles have been associated with a significant decrease in clopidogrel responsiveness and a higher risk of adverse cardiac events including stent thrombosis, myocardial infarction, and death in several prospective studies, although these effects were not reproduced in a recent large randomized study that included a randomized control group. clopidogrel 85-96 cytochrome P450 family 2 subfamily C member 19 Homo

determining the rate of active metabolite and the clinical activity of clopidogrel. clopidogrel 223-234 paraoxonase 1 Homo sapiens 41-45 21592545-9 2011 Further studies are needed to investigate the comprehensive influence of a number of different polymorphisms of CYP2C19 and PON1 variant alleles or other genetic variants on clopidogrel in various ethnic populations. clopidogrel 174-185

reactivity index vasoactive-stimulated phosphoprotein, was significantly affected by genotype, with lower clopidogrel response in CYP2C19*2 allele carriers (p = 0.01). clopidogrel 0-11 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 175-182 21803320-5 2011 Clopidogrel response, assessed with platelet reactivity index vasoactive-stimulated phosphoprotein, was significantly affected by genotype, with lower clopidogrel response in CYP2C19*2 allele carriers (p = 0.01). clopidogrel 151-162 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 175-182 21803320-6 2011 Accordingly,

oral dose of clopidogrel, but not aspirin, significantly reduced the release of BDNF from platelets in healthy volunteers. clopidogrel 41-52 brain derived neurotrophic factor Homo sapiens 108-112 21875913-1 2011 BACKGROUND: In the Gauging Responsiveness With A VerifyNow P2Y12 Assay: Impact on Thrombosis and Safety (GRAVITAS) trial, 6 months of high-dose clopidogrel did not reduce

BACKGROUND: In the Gauging Responsiveness With A VerifyNow P2Y12 Assay: Impact on Thrombosis and Safety (GRAVITAS) trial, 6 months of high-dose clopidogrel did not reduce cardiovascular events compared with standard-dose clopidogrel in patients with high on-treatment platelet reactivity (OTR) after percutaneous coronary intervention, defined as OTR >=230 P2Y12 reaction units according to the VerifyNow P2Y12 platelet function test. clopidogrel 221-232 purinergic receptor P2Y12 Homo sapiens 59-64 21875913-8 2011 CONCLUSIONS: In the GRAVITAS trial, achievement of on-clopidogrel reactivity <208 P2Y12 reaction units at 12 to 24 hours after percutaneous coronary intervention or during follow-up was associated with a lower risk for cardiovascular events. clopidogrel 54-65 purinergic receptor P2Y12 Homo sapiens 85-90 21884870-1 2011 BACKGROUND: Pharmacodynamic studies reported an amplified on-clopidogrel platelet inhibition in smokers potentially caused by an increased metabolic drug activation via induction of cytochrome P450 1A2. clopidogrel 61-72 cytochrome P450 family 1 subfamily A member 2 Homo sapiens 182-201 21620406-6 2011 RESULTS: Several preventive treatments (statins and clopidogrel) were significantly associated with lower Lp-PLA(2) mass and activity. clopidogrel 52-63 phospholipase A2 group VII Homo sapiens 106-115 21706290-5 2011 Polymorphisms of genes encoding the cytochrome enzymes and P-glycoprotein involved in clopidogrel absorption are regarded as major determinants of the interindividual variability in the clopidogrel-induced platelet inhibition. clopidogrel 186-197 ATP binding cassette subfamily B member 1 Homo sapiens 59-73 21479772-3 2011 METHODS: ADP- and TRAP-induced platelet aggregation was measured by impedance aggregometry in 28 patients with coronary stent implantation (observational group, OG) before and 1, 2, 6 and 17 weeks after clopidogrel cessation. clopidogrel 203-214 TRAP Homo sapiens 18-22 21455672-2 2011 AIMS: The aim of this study was to compare the rates of PPB for clopidogrel users and non-users. clopidogrel 64-75 histatin 1 Homo sapiens 56-59 21455672-4 2011 We compared the frequency of delayed PPB (within 30 days) for patients on uninterrupted clopidogrel therapy with patients not taking clopidogrel. clopidogrel 88-99 histatin 1 Homo sapiens 37-40 21455672-9 2011 CONCLUSIONS: The delayed PPB rate for our patients on clopidogrel was less than 1%, and PPB rates did not differ significantly between users and non-users. clopidogrel 54-65 histatin 1 Homo sapiens 25-28 21684710-12 2011 Preoperative treatment with clopidogrel, particularly when it is continued to the day before surgery, and postoperative arterial hypertension seem to be associated with a higher risk of neck bleeding after CEA, requiring re-exploration in most cases. clopidogrel 28-39 CEA cell adhesion molecule 3 Homo sapiens 206-209 21806387-10 2011 CONCLUSION: Genetic variants in CYP2C19 have a gene-dose effect on post-clopidogrel platelet reactivity, with homozygote LOF carriers having the highest risk for HTPR and for adverse ischemic events. clopidogrel 72-83 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 32-39 21792575-5 2011 The latter receptor, the molecular target of the antithrombotic drugs clopidogrel, prasugrel and ticagrelor, is responsible for most of the potentiating effects of ADP when platelets are stimulated by agents such as thrombin, collagen or immune complexes. clopidogrel 70-81 coagulation factor II, thrombin Homo sapiens 216-224 21786436-0 2011 Cytochrome P450 2C19 polymorphism is associated with reduced clopidogrel response in cerebrovascular disease. clopidogrel 61-72 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 0-20 21786436-1 2011 PURPOSE: Clopidogrel is a prodrug that requires transformation into an active metabolite by cytochrome P450 (CYP) in the liver in order to irreversibly inhibit the P2Y12 adenosine diphosphate platelet receptor. clopidogrel 9-20 purinergic receptor P2Y12 Homo sapiens 164-169 21786436-2 2011 CYP2C19 polymorphism has been reported to correlate with reduced antiplatelet activity of clopidogrel in coronary artery disease. clopidogrel 90-101 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 0-7 21786436-3 2011 We assessed the association between CYP2C19 polymorphism and clopidogrel resistance in patients with cerebrovascular disease. clopidogrel 61-72 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 36-43 21786436-6 2011 Clopidogrel resistance was expressed in P2Y12 reaction units (PRU) and percent inhibition. clopidogrel 0-11 purinergic receptor P2Y12 Homo sapiens 40-45 21786436-9 2011 Clopidogrel resistance was assessed according to the subgroup of CYP2C19 polymorphism. clopidogrel 0-11 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 65-72 21786436-13 2011 CONCLUSION: Intermediate and poor metabolizing CYP2C19 polymorphism is associated with reduced clopidogrel antiplatelet activity in patients with cerebrovascular disease. clopidogrel 95-106 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 47-54 21719206-0 2011 Does CYP2C19 inhibition lead to clopidogrel thrombogenicity? clopidogrel 32-43 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 5-12 21719206-4 2011 Thus a hypothesis is proposed, that the combination of proton-pump inhibitors and clopidogrel increases mortality as results of thrombogenic metabolites of clopidogrel, due to inhibition of CYP2C19 by proton-pump inhibitors. clopidogrel 82-93 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 190-197 21646658-2 2011 The antiplatelet effects of clopidogrel originate through noncompetitive antagonism of the platelet ADP receptor, P2Y12, resulting in inhibition of platelet activation. clopidogrel 28-39 purinergic receptor P2Y12 Homo sapiens 114-119 21826075-4 2011 The most robust data

2C19*2 polymorphism have significantly increased platelet reactivity compared to patients with the wild-type, evaluated with the VASP determination, and even more pronounced with the VerifyNow P2Y12 method. clopidogrel 13-24 vasodilator stimulated phosphoprotein Homo sapiens 184-188 21426546-13 2011 CONCLUSIONS: Clopidogrel treated patients with the CYP 2C19*2 polymorphism have significantly

receptor P2Y12 Homo sapiens 248-253 30524601-0 2011 Repeated intra-stent thrombus formation in a patient with acute coronary syndrome due to poor responsiveness to clopidogrel may be associated with cytochrome P-450 2C19*2 polymorphism. clopidogrel 112-123 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 147-168 30524601-6 2011 This case suggests that the mechanism of stent thrombosis, while multi-factorial, is affected greatly by crossover of poor responsiveness to clopidogrel due to the CYP2C19*2 polymorphism. clopidogrel 141-152 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 164-171 21392639-2 2011 Clopidogrel, a prodrug, requires hepatic cytochrome P450 (CYP) metabolic activation to produce the active metabolite that inhibits the platelet P2Y12 adenosine

prodrug, requires hepatic cytochrome P450 (CYP) metabolic activation to produce the active metabolite that inhibits the platelet P2Y12 adenosine diphosphate (ADP) receptor, decreasing platelet activation and aggregation processes. clopidogrel 0-11 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 58-61 21392639-3 2011 Atorvastatin, omeprazole, and several other drugs have been shown in pharmacodynamic studies to competitively inhibit CYP activation of clopidogrel, reducing clopidogrel responsiveness. clopidogrel 136-147 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 118-121 21392639-3 2011 Atorvastatin, omeprazole, and several other drugs have been shown in pharmacodynamic studies to competitively inhibit CYP activation of clopidogrel, reducing

universal but was observed only in cytochrome P450 CYP1A2 (-163C>A) A-allele carriers, suggesting a genotype-dependent effect of smoking on clopidogrel responsiveness. clopidogrel 22-33 cytochrome P450 family 1 subfamily A member 2 Homo sapiens 144-150 21148426-10 2011 CONCLUSIONS: Enhanced clopidogrel response in smokers, known as the smokers" paradox, is not universal but was observed only in cytochrome P450 CYP1A2 (-163C>A) A-allele carriers, suggesting a genotype-dependent effect of smoking on clopidogrel responsiveness. clopidogrel 236-247 cytochrome P450 family 1 subfamily A member 2

before PCI decreases peri-procedural P-selectin levels; moreover, a 600 mg clopidogrel loading dose, compared with the 300 mg regimen, is associated with reduction of peri-procedural myocardial damage and significant attenuation of P-selectin levels at the time of intervention. clopidogrel 30-41 selectin P Homo sapiens 79-89 21085001-7 2011 CONCLUSION: Pretreatment with clopidogrel before PCI decreases peri-procedural P-selectin levels; moreover, a 600 mg clopidogrel loading dose, compared with the 300 mg regimen, is associated with reduction of peri-procedural myocardial damage and significant attenuation of P-selectin levels at the time of intervention. clopidogrel 30-41 selectin P Homo sapiens 274-284 21085001-7 2011 CONCLUSION: Pretreatment with clopidogrel before PCI decreases peri-procedural P-selectin levels; moreover, a 600 mg clopidogrel loading dose, compared with the 300 mg regimen, is associated with reduction of peri-procedural myocardial damage and significant attenuation of P-selectin levels at the time of intervention. clopidogrel 117-128 selectin P Homo sapiens 274-284 21168310-1 2011 BACKGROUND AND PURPOSE: CYP2C19*2 loss-of-function allele in Caucasians may be associated with wide interindividual variability in platelet response to clopidogrel, and the incidence of gene mutation varies with racial differences, especially between Asians and Caucasians. clopidogrel 152-163 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 24-31 29783409-5 2011 One needs only to look to the developing research associated with CYP2C19 genetic testing, a marker that indicates a poor response to the antiplatelet therapy clopidogrel for some 30% of patients that carry the specific alleles. clopidogrel 159-170 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 66-73 20845077-0 2011 Cytochrome P450 2C19 polymorphism is associated with poor clinical outcomes in coronary artery disease patients treated with clopidogrel.

nonresponsiveness to clopidogrel. clopidogrel 103-114 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 17-20 20427204-9 2011 COL-MEA and ADP-MEA discriminated between preoperative ASA and clopidogrel intake (ASA: sensitivity = 86.3%, and specificity = 89.3%; clopidogrel: sensitivity = 87.5%, and specificity = 95.1%). clopidogrel 63-74 WD and tetratricopeptide repeats 1 Homo sapiens 12-19 21509344-3 2011 Current consensus recommendations state that patients prescribed clopidogrel plus aspirin should receive a proton pump inhibitor (PPI) to reduce gastrointestinal bleeding. clopidogrel 65-76 ATPase H+/K+ transporting subunit alpha Homo sapiens 107-118 20966167-6 2011 Clopidogrel, the most widely used drug that inhibits P2Y12, is effective both in monotherapy and in combination with acetylsalicylic acid. clopidogrel 0-11 purinergic receptor P2Y12 Homo sapiens 53-58 20966167-7 2011 The most important drawback of clopidogrel is its inability to inhibit adequately P2Y12-dependent platelet function in approximately one-third of patients who are therefore not protected from major cardiovascular events. clopidogrel 31-42 purinergic receptor P2Y12 Homo sapiens 82-87 21310311-6 2011 Higher clopidogrel dose was associated with decreased proportion of patients with P2Y(12) reaction units >= 240 (12% vs. 32%; p = 0.001), flow-mediated vasodilation <7% (16% vs. 58%; p = 0.0003), and high-sensitivity C-reactive protein levels >3 mg/l (46% vs. 64%; p = 0.07). clopidogrel 7-18 C-reactive protein Homo sapiens 223-241 21285422-0 2011 Carriage of reduced-function

cytochrome P450 family 2 subfamily C member 19 Homo sapiens 24-31 21178986-1 2011 We examined the influence of CYP2C19 polymorphisms on the antiplatelet effects of clopidogrel and ticlopidine. clopidogrel 82-93 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 29-36 21178986-3 2011 The degree of platelet aggregation in the clopidogrel group, although not in the ticlopidine group, depended on the CYP2C19 polymorphism, and the maximal platelet aggregation in poor metabolizers (PMs) taking clopidogrel was equivalent to that in the group taking aspirin alone. clopidogrel 42-53 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 116-123 21178986-5 2011 These results suggest that CYP2C19 polymorphisms have a profound impact on the antiplatelet effect of clopidogrel but not on that of ticlopidine. clopidogrel 102-113 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 27-34 20427204-10 2011 The postoperative transfusion risk was increased in patients diagnosed for clopidogrel treatment by ADP-MEA (odds ratio = 2.92; confidence interval: 1.44-5.92; p = 0.005). clopidogrel 75-86 WD and tetratricopeptide repeats 1 Homo sapiens 100-107 21297211-4 2011 Laboratory evaluation of hypercoagulability yielded negative results, but low responsiveness for clopidogrel was revealed by the VerifyNow P2Y12 assay. clopidogrel 97-108 purinergic receptor P2Y12 Homo sapiens 139-144 21262444-3 2011 In contrast, resistance to clopidogrel (a P2Y12 inhibitor), which is mostly due to inefficient metabolism of the pro-drug clopidogrel to its active metabolite, is a rather frequent condition, which is associated with lower clinical efficacy of the drug. clopidogrel 27-38 purinergic receptor P2Y12 Homo sapiens 42-47 21262444-3 2011 In contrast, resistance to clopidogrel (a P2Y12 inhibitor), which is mostly due to inefficient metabolism of the pro-drug clopidogrel to its active metabolite, is a rather frequent condition, which is associated with lower clinical efficacy of the drug. clopidogrel 122-133 purinergic receptor P2Y12 Homo sapiens 42-47 21262444-5 2011 The use of new P2Y12 inhibitors, such as prasugrel and ticagrelor, which adequately inhibit P2Y12-dependent platelet function in the vast majority of treated subjects, appears the best solution to the problem of clopidogrel resistance. clopidogrel 212-223 purinergic receptor P2Y12 Homo sapiens 15-20 21251579-0 2011 Cardiovascular mortality in chronic kidney disease patients undergoing percutaneous coronary intervention is mainly related to impaired P2Y12 inhibition by clopidogrel. clopidogrel 156-167 purinergic receptor P2Y12 Homo sapiens 136-141 21256376-0 2011 Double-dose clopidogrel in patients undergoing PCI for ACS. clopidogrel 12-23

(SJW), a CYP2C19 and CYP3A4 inducer, enhances the pharmacodynamic response of clopidogrel. clopidogrel 115-126 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 46-53 21217483-3 2011 We report the use of a new P2Y12 point-of-care assay (VerifyNow; Accumetrics, San Diego, CA) to determine the magnitude of platelet inhibition in trauma patients using clopidogrel. clopidogrel 168-179 purinergic receptor P2Y12 Homo sapiens 27-32 21217483-11 2011 CONCLUSIONS: The P2Y12 point-of-care assay determined that a large percentage of patients had undetectable or low platelet inhibition despite reportedly being on clopidogrel therapy. clopidogrel 162-173 purinergic receptor P2Y12 Homo sapiens 17-22 21771376-1 2011 As both proton pump inhibitors (PPIs) and clopidogrel are metabolized by CYP2C19, an enzyme of the cytochrome P450 system, this could lead to drug competition. clopidogrel 42-53 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 73-80 21771377-3 2011 Concomitant use of omeprazole and clopidogrel was found to decrease the exposure (AUC) to clopidogrel"s active metabolite by 50% and to sharply increase platelet reactivity, as a result of inhibition by omeprazole of CYP2C19, a cytochrome P450 (CYP) enzyme. clopidogrel 34-45 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 217-224 21771377-3 2011 Concomitant use of omeprazole and clopidogrel was found to decrease the exposure (AUC) to clopidogrel"s active metabolite by 50% and to sharply increase platelet reactivity, as a result of inhibition by omeprazole of CYP2C19, a

the exposure (AUC) to clopidogrel"s active metabolite by 50% and to sharply increase platelet reactivity, as a result of inhibition by omeprazole of CYP2C19, a cytochrome P450 (CYP) enzyme. clopidogrel 34-45 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 217-220 20873965-4 2011 We tested this cartridge for its capacity to detect the inhibition of the P2Y12 receptor, which is the target for thienopyridine medication (e.g. clopidogrel). clopidogrel 146-157 purinergic receptor P2Y12 Homo sapiens 74-79 20873965-7 2011 In volunteers, the intake of a 600 mg clopidogrel loading dose caused an increase of the CTs in all volunteers, although some of these volunteers were identified as "poor responders" by the VASP assay (no significant reduction of PRI levels). clopidogrel

between the cytochrome P450 2C19 (CYP2C19) *2 polymorphism (681A) and definite stent thrombosis (ST) in patients undergoing percutaneous coronary intervention (PCI) and receiving clopidogrel (75 mg/day, orally). clopidogrel 220-231 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 53-73 22118006-1 2011 This study investigated the relationship between the cytochrome P450 2C19 (CYP2C19) *2 polymorphism (681A) and definite stent thrombosis (ST) in patients undergoing percutaneous coronary intervention (PCI) and receiving clopidogrel (75 mg/day, orally). clopidogrel 220-231 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 75-82 22118006-6 2011 The CYP2C19*2 genotype is associated with an increased risk of definite ST following coronary stent placement among

determinant of clopidogrel efficacy. clopidogrel 40-51 paraoxonase 1 Homo sapiens 0-13 21170047-3 2011 Using in vitro metabolomic profiling techniques, we identified paraoxonase-1 (PON1) as the crucial enzyme for clopidogrel bioactivation, with its common Q192R polymorphism determining the rate of active metabolite formation. clopidogrel 110-121 paraoxonase 1 Homo sapiens 63-76 21170047-3 2011 Using in vitro metabolomic profiling techniques, we identified paraoxonase-1 (PON1) as the crucial enzyme for clopidogrel bioactivation, with its common Q192R polymorphism determining the rate of active metabolite formation. clopidogrel 110-121 paraoxonase 1 Homo sapiens 78-82 21170047-4 2011 We tested the clinical relevance of the PON1 Q192R genotype in a population of individuals with coronary artery disease who underwent stent implantation and received clopidogrel therapy. clopidogrel 166-177 paraoxonase 1 Homo sapiens 40-44 21170047-6 2011 Thus, we identified PON1 as a key factor for the bioactivation and clinical activity of clopidogrel. clopidogrel 88-99 paraoxonase 1 Homo sapiens 20-24 21251580-2 2011 BACKGROUND: CCBs inhibit a variety of cytochrome P-450 enzymes, some of which contribute to clopidogrel metabolic activation. clopidogrel 92-103 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 38-54 21627411-8 2011 Only one gene polymorphism (CYP2C19*17) increases the clopidogrel metabolization and so the clopidogrel-induced platelet inhibition. clopidogrel 92-103 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 28-35 23226058-6 2011 When a prodrug, such as clopidogrel or codeine, must undergo hepatic biotransformation to its active form, a loss-of-function P450 genotype leads to reduced concentrations of the active drug and decreased drug efficacy. clopidogrel 24-35 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 126-130 22028806-0 2011 Clopidogrel, a P2Y12 receptor antagonist, potentiates the inflammatory response in a rat model of peptidoglycan polysaccharide-induced arthritis. clopidogrel 0-11 purinergic receptor P2Y12 Rattus norvegicus 15-20 22028806-1 2011 The P2Y12 receptor plays a crucial role in the regulation of platelet activation by several agonists, which is irreversibly antagonized by the active metabolite of clopidogrel, a widely used anti-thrombotic drug. clopidogrel 164-175 purinergic receptor P2Y12 Rattus norvegicus 4-9 22028806-4 2011 There were significant differences between the PG-PS+clopidogrel group when compared to the PG-PS group including: increased joint diameter and clinical manifestations of inflammation, elevated plasma levels of pro-inflammatory cytokines (IL-1 beta, interferon (IFN) gamma, and IL-6), an elevated neutrophil blood count and an increased circulating platelet count. clopidogrel 53-64 interleukin 6 Rattus norvegicus 278-282 22028806-5 2011 Plasma levels of IL-10 were significantly lower in the PG-PS+clopidogrel group compared to the PG-PS group. clopidogrel 61-72 interleukin 10 Rattus norvegicus 17-22 22028806-6 2011 Plasma levels of platelet factor 4 (PF4) were elevated in both the PG-PS and the PG-PS+clopidogrel groups, however PF4 levels showed no difference upon clopidogrel treatment, suggesting that the pro- inflammatory effect of clopidogrel may be due to its action on cells other than platelets. clopidogrel 87-98 platelet factor 4 Rattus norvegicus 36-39 22028806-9 2011 Elucidation of the mechanism of clopidogrel-induced cell responses is important to understand the role of the P2Y12 receptor in inflammation. clopidogrel 32-43 purinergic receptor P2Y12 Rattus norvegicus 110-115 21627411-3 2011 Clopidogrel pro-drug is absorbed in the intestine and this process is influenced by P-glycoprotein-1 (P-GP). clopidogrel 0-11 ATP binding cassette subfamily B member 1 Homo sapiens 84-100 21627411-3 2011 Clopidogrel pro-drug is absorbed in the intestine and this process is influenced by P-glycoprotein-1 (P-GP). clopidogrel 0-11 ATP binding cassette subfamily B member 1 Homo sapiens 102-106 21627411-8 2011 Only one gene polymorphism (CYP2C19*17) increases the clopidogrel metabolization and so the clopidogrel-induced platelet inhibition. clopidogrel 54-65 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 28-35 21703110-4 2011 Prevalence of co-prescribing of clopidogrel, aspirin and PPI in diabetic patients and clopidogrel with various CYP2C19 inhibitors was also examined. clopidogrel 86-97 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 111-118 21703110-11 2011 Only one patient on clopidogrel was receiving a CYP2C19 inhibitor in addition to a PPI. clopidogrel 20-31 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 48-55 21546883-2 2011 The thienopyridine clopidogrel is a prodrug that requires bioactivation by the cytochrome P450 (CYP) system in order to exert its antiplatelet effect. clopidogrel 19-30 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 79-94 21546883-2 2011 The thienopyridine clopidogrel is a prodrug that requires bioactivation by the cytochrome P450 (CYP) system in order to exert its antiplatelet effect. clopidogrel 19-30 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 96-99 21546883-3 2011 Common genetic polymorphisms that reduce the catalytic activity of the CYP2C19 isoenzyme decrease circulating levels of active metabolite, reduce levels of platelet inhibition, and increase the risk of ischemic events in clopidogrel-treated patients. clopidogrel 221-232 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 71-78 21546883-4 2011 Herein, we review the impact of the CYP2C19 genotype on the pharmacokinetics and pharmacodynamics of clopidogrel, the association between CYP2C19 genotype and clinical outcome, and present the rationale for the implementation of CYP2C19 genotyping to individualize antiplatelet therapy in clinical practice. clopidogrel 101-112 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 36-43 22080983-6 2011 This article reviews the impact of poor clopidogrel responsiveness on clinical outcomes, the major clinical studies using VerifyNow P2Y12 Assay (Accumetrics, San Diego, CA) to assess on-clopidogrel platelet reactivity, and efforts to determine a reliable cutoff. clopidogrel 203-214 purinergic receptor P2Y12 Homo sapiens 148-153 21075428-1 2011 INTRODUCTION: Carriage of CYP2C19*2 allele is associated with diminished platelet response to clopidogrel. clopidogrel 94-105 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 26-33 21901881-4 2011 The causes of clopidogrel resistance include inadequate doses of the drug, its low absorption, poor compliance with the treatment, polymorphism of ADP receptors, GP IIb/IIIa and cytochrome P450 genes, acute coronary syndrome and stroke, metabolic syndrome. clopidogrel 14-25 integrin subunit alpha 2b Homo sapiens 162-168 21075428-2 2011 However, the loss-of-function impact of CYP2C19*3 allele on antiplatelet effect of clopidogrel has not been definitely verified. clopidogrel 83-94 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 40-47 21075428-3 2011 We conducted this study to compare decreased response to clopidogrel according to carriage of CYP2C19*2 vs. *3 allele. clopidogrel 57-68 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 94-101 21075428-12 2011 CONCLUSION: Carriage of CYP2C19*3 allele is associated with diminished antiplatelet effect of clopidogrel, which may be as potent as the loss-of-function effect of CYP2C19*2 allele. clopidogrel 94-105 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 24-31 21133697-0 2010 Backtracking on CYP2C19 genotyping in clopidogrel therapy? clopidogrel 38-49 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 16-23 21079055-12 2010 Whereas CYP2C19 genotype influenced the antiplatelet effect of clopidogrel, there was no effect of CYP2C19 genotype during ticagrelor therapy. clopidogrel 63-74 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 8-15 21111931-3 2010 Clopidogrel is a pro-drug that needs metabolic activation through a cytochrome P450-dependent pathway, with an extensive involvement of the CYP 2C19 isoenzyme. clopidogrel 0-11 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 140-148 21111931-5 2010 In the past two years some scientific evidences have suggested a possible negative interference of PPIs on antiplatelet effect of clopidogrel because of the competitive inhibition of the CYP 2C19 isoenzyme. clopidogrel 130-141 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 187-195 21084035-4 2010 The possible relative risk factors included advanced age, chronic and systemic diseases, and co-administration of cytochrome P450 3A (CYP3A) enzyme-dependent metabolic drugs or its inhibitors such as clopidogrel and diltiazem. clopidogrel 200-211 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 114-132 21084035-4 2010 The possible relative risk factors included advanced age, chronic and systemic diseases, and co-administration of cytochrome P450 3A (CYP3A) enzyme-dependent metabolic drugs or its inhibitors such as clopidogrel and diltiazem. clopidogrel 200-211 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 134-139 21073556-2 2010 Interactions described include those between aspirin and ibuprofen, aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs), and the thienopyridine, clopidogrel, and drugs inhibiting CYP2C19, notably the proton pump inhibitors (PPI) omeprazole and esomeprazole. clopidogrel 157-168 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 191-198 21073556-11 2010 For the clopidogrel CYP2C19 and CYP3A4/5 interactions, there is good evidence that these interactions occur. clopidogrel 8-19 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 20-27 21073556-11 2010 For the clopidogrel CYP2C19 and CYP3A4/5 interactions, there is good evidence that these interactions occur. clopidogrel 8-19 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 32-38 21073556-13 2010 Again, a reasonable strategy is to avoid the chronic use of drugs that inhibit CYP2C19, notably PPIs, in subjects taking clopidogrel and use high dose H2 antagonists instead. clopidogrel 121-132 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 79-86 20838744-2 2010 Both high levels of C-reactive protein (CRP)and high on-clopidogrel treatment platelet reactivity (HPR) have been linked to an increased risk of ischaemic events after percutaneous coronary intervention (PCI). clopidogrel 56-67 haptoglobin-related protein Homo sapiens 99-102 20838744-9 2010 In conclusion, elevated levels of CRP, WBC count

cytochrome P450 family 2 subfamily C member 19 Homo sapiens 170-177 20801498-2 2010 CYP2C19 and ABCB1 genotypes are known to influence the effects of clopidogrel. clopidogrel 66-77 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 0-7 21057581-7 2010 A delayed onset of action due to two-step conversion to the active metabolite, irreversible binding to P2Y12 receptors, and broad

genotyped ABCB1 in 2932 patients with acute coronary syndromes undergoing percutaneous intervention who were treated with clopidogrel (n=1471) or prasugrel (n=1461) in the TRITON-TIMI 38 trial. clopidogrel 134-145 ATP binding cassette subfamily B member 1 Homo sapiens 22-27 20801494-9 2010 FINDINGS: In patients treated with clopidogrel, ABCB1 3435C T genotype was significantly associated

Individuals with the ABCB1 3435 TT genotype have reduced platelet inhibition and are at increased risk of recurrent ischaemic events during clopidogrel treatment. clopidogrel 156-167 ATP binding cassette subfamily B member 1 Homo sapiens 37-42 20823393-1 2010 BACKGROUND: Among patients treated with clopidogrel, carriers of the cytochrome P450 (CYP) 2C19 loss-of-function allele have shown increased platelet reactivity and higher rates of ischemic events. clopidogrel 40-51 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 69-95 20942779-8 2010 Numerous clinical studies have shown the influence of CYP2C19 polymorphism on clopidogrel antiplatelet activity. clopidogrel 78-89 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 54-61 20942779-10 2010 Several studies have also demonstrated that CYP3A4/5 and CYP1A2 are important in clopidogrel bioactivation and should also be considered as potential targets for unwanted drug-drug interactions. clopidogrel 81-92

1 Homo sapiens 12-17 20801498-8 2010 For the ABCB1 genotype, event rates for the primary outcome were also consistently lower in the ticagrelor than in the clopidogrel group for all genotype groups (interaction p=0 39; 8 8%vs 11 9%; 0 71, 0 55-0 92 for the high-expression genotype). clopidogrel 119-130 ATP binding cassette subfamily B member 1 Homo sapiens 8-13 20801498-9 2010 In the clopidogrel group, the event rate at 30 days was higher in patients with than in those without any loss-of-function CYP2C19 alleles (5 7%vs 3 8%, p=0 028), leading to earlier separation of event rates between treatment groups in patients with loss-of-function alleles. clopidogrel 7-18 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 123-130 20801498-10 2010 Patients on clopidogrel who had any gain-of-function CYP2C19 allele had a higher frequency of major bleeding (11 9%) than did those without any gain-of-function or loss-of-function alleles (9 5%; p=0 022), but interaction between treatment and genotype groups was not significant for any type of major bleeding. clopidogrel 12-23 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 53-60 20451958-9 2010 These results may

118-125 21268429-4 2010 Various PPIs can inhibit CYP2C19, which could possibly decrease clopidogrel bioactivation process and, therefore, its antiplatelet effect. clopidogrel 64-75 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 25-32 20877456-7 2010 Testing for CYP2C19 polymorphisms may identify patients who will not respond adequately to the standard clopidogrel regimen and who

sapiens 32-39 20083681-1 2010 BACKGROUND: The cytochrome P450 (CYP) 2C19 isoenzyme plays an important role in clopidogrel metabolization. clopidogrel 80-91 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 16-42 20083681-2 2010 A recently explored CYP2C19*17 allelic variant has been linked to increased transcriptional activity, resulting in extensive metabolization of CYP2C19 substrates,

CYP2C19*17 allelic variant has been linked to increased transcriptional activity, resulting in extensive metabolization of CYP2C19 substrates, which may lead to an enhanced platelet response to clopidogrel treatment. clopidogrel 214-225 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 143-150 20083681-3 2010 The aim of this study was to assess the impact of CYP2C19*17 on

subfamily C member 19 Homo sapiens 50-57 20083681-12 2010 CONCLUSIONS: CYP2C19*17 carrier status is significantly associated with enhanced response to clopidogrel and an increased risk of bleeding. clopidogrel 93-104 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 13-20 19902490-10 2010 Clopidogrel efficacy was assessed by measurement of vasodilator-stimulated phosphoprotein

widely prescribed anti-platelet drugs, are metabolized to active compounds that covalently and irreversibly modify their respective therapeutic targets (COX1 and P2Y12). clopidogrel 12-23 mitochondrially encoded cytochrome c oxidase I Homo sapiens 191-195 20094648-2 2010 Aspirin and clopidogrel, the two most widely prescribed anti-platelet drugs, are metabolized to active compounds that covalently and irreversibly modify their respective therapeutic targets (COX1 and P2Y12). clopidogrel 12-23 purinergic receptor P2Y12 Homo sapiens 200-205 20094648-4 2010 As clopidogrel must be activated by cytochrome P450 metabolism, recent pharmacogenomic studies have revealed that patients lacking a functional allele of CYP2C19 derive no therapeutic benefit from the drug. clopidogrel 3-14 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 154-161 20126830-1 2010 Novel P2Y12 inhibitors are in development to overcome the occurrence of atherothrombotic events associated with poor

occurrence of atherothrombotic events associated with poor responsiveness to the widely used P2Y12 inhibitor clopidogrel. clopidogrel 167-178 purinergic receptor P2Y12 Homo sapiens 151-156 20653328-4 2010 However, laboratory and clinical experience with clopidogrel have led to understanding some of the limitations of this drug, the most important of which is its broad range in interindividual response variability, resulting in the development of novel ADP P2Y12 receptor-inhibiting strategies. clopidogrel 49-60 purinergic receptor P2Y12 Homo sapiens 255-260 20653328-5 2010 This article provides an overview of ADP P2Y12 receptor-inhibiting strategies, including high clopidogrel dosing regimens and novel agents under advanced clinical development. clopidogrel 94-105 purinergic receptor P2Y12 Homo sapiens 41-46 19934793-0 2010 Besides CYP2C19*2, the variant allele CYP2C9*3 is associated with higher on-clopidogrel platelet reactivity in patients on dual antiplatelet therapy undergoing elective coronary stent implantation. clopidogrel 76-87 cytochrome P450 family 2 subfamily C member 9 Homo sapiens 38-44 20924183-1 2010 OBJECTIVES: To determine whether the 681 G>A (*2) polymorphism of cytochrome P450 (CYP2C19) is related to suboptimal reperfusion and mortality in patients with acute myocardial infarction (AMI) pretreated with clopidogrel. clopidogrel 213-224 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 86-93 20924183-11 2010 CONCLUSIONS: The CYP2C19*2 allele is an independent predictor of suboptimal reperfusion in patients with AMI undergoing PCI with stenting after pretreatment with clopidogrel and may increase the risk of all-cause mortality. clopidogrel 162-173 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 17-24 20966600-8 2010 The rate of low responsiveness to clopidogrel, defined by VASP index > 50%, was lower in the triple therapy group than in the dual therapy group (12.5% versus 55.9%; P = 0.047). clopidogrel 34-45 vasodilator stimulated phosphoprotein Homo sapiens 58-62 20966600-9 2010 Similarly, in DM patients the triple therapy group had a lower VASP index compared with the dual therapy group (23.1 +- 15.3% versus 47.0 +- 23.5%; P = 0.015).Clopidogrel plus cilostazol is more effective in inhibiting the platelet P2Y(12) ADP receptor pathway than clopidogrel alone. clopidogrel 159-170 vasodilator stimulated phosphoprotein Homo sapiens 63-67 19018951-6 2010 Patients taking clopidogrel 75 mg for >or=7 days, 300 mg for 24 hours, and 600 mg same day load had a mean P2Y12/ADP inhibition of 45%, 35% (P-value = .09), and 16%, respectively (P-value = .005). clopidogrel 16-27 purinergic receptor P2Y12 Homo sapiens 110-115 20659022-7 2010 It has been shown recently that loss of function alleles of some CYP450 genes especially CYP2C19*2 are responsible for reduced reaction of platelets to clopidogrel. clopidogrel 152-163 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 89-96 20831051-2 2010 In a series of articles the authors consider clinical pharmacology and experience of clinical application of blockers of platelet P2Y12 receptors, most well known representatives of which ticlopidine and clopidogrel according to chemical structure belong to thienopyridine derivatives. clopidogrel 204-215 purinergic receptor P2Y12 Homo sapiens 130-135 19904241-12 2010 As the presence of PPIs and clopidogrel in plasma is short lived, separation by 12-20 h should in theory prevent competitive inhibition of CYP metabolism and minimize any potential, though unproven, clinical interaction. clopidogrel 28-39 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 139-142 19855266-7 2010 Levels of CD62P, CD63, and CD40L were more significantly reduced in the clopidogrel group than in the aspirin group in the first week after stroke. clopidogrel 72-83 selectin P Homo sapiens 10-15 19855266-7 2010 Levels of CD62P, CD63, and CD40L were more significantly reduced in the clopidogrel group than in the aspirin group in the first week after stroke. clopidogrel 72-83 CD63 molecule Homo sapiens 17-21 19855266-7 2010 Levels of CD62P, CD63, and CD40L were more significantly reduced in the clopidogrel group than in the aspirin group in the first week after stroke. clopidogrel 72-83 CD40 ligand Homo sapiens 27-32 22291500-3 2010 From pharmacologic and pharmacodynamic perspectives, there is a real interaction between clopidogrel and PPIs because of the competitive inhibition of CYP2C19 isoenzyme which is required for biotransformation of clopidogrel to its active metabolite. clopidogrel 89-100 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 151-158 22291500-3 2010 From pharmacologic and pharmacodynamic perspectives, there is a real interaction between clopidogrel and PPIs because of the competitive inhibition of CYP2C19 isoenzyme which is required for biotransformation of clopidogrel to its active metabolite. clopidogrel 212-223 cytochrome

its pharmacologically active metabolite. clopidogrel 112-123 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 39-43 19812348-1 2010 The aim of the current study is to identify the human cytochrome P450 (P450) isoforms involved in the two oxidative steps in the bioactivation of clopidogrel to its pharmacologically active metabolite. clopidogrel 146-157 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 65-69 19812348-1 2010 The aim of the current study is to identify the human cytochrome P450 (P450) isoforms involved in the two oxidative steps in the bioactivation of clopidogrel to its pharmacologically active metabolite. clopidogrel 146-157 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 71-75 19812348-2 2010 In the in vitro experiments using cDNA-expressed human P450 isoforms, clopidogrel was metabolized to 2-oxo-clopidogrel, the immediate precursor of its pharmacologically active metabolite. clopidogrel 70-81 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 55-59 19812348-10 2010 These studies showed that CYP2C19 contributed substantially to both oxidative steps required in the formation of clopidogrel active metabolite and that CYP3A4 contributed substantially to the second oxidative step. clopidogrel 113-124 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 26-33 19812348-10 2010 These studies showed that CYP2C19 contributed substantially to both oxidative steps required in the formation of clopidogrel active metabolite and that CYP3A4 contributed substantially to the second oxidative step. clopidogrel 113-124 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 152-158 19812348-11 2010 These results help explain the role of genetic polymorphism of CYP2C19 and also the effect of potent CYP3A inhibitors on the pharmacokinetics and pharmacodynamics of clopidogrel in humans and on clinical outcomes. clopidogrel 166-177 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 63-70 20035517-2 2010 We report a Janus kinase 2-homozygous patient with BCS who thrombosed a transjugular intrahepatic portosystemic shunt (TIPS) despite treatment with warfarin (international normalized ratio = 3.0), aspirin, and clopidogrel. clopidogrel 210-221 Janus kinase 2 Homo sapiens 12-26 20217574-7 2010 Additionally, the assay has been used to demonstrate that CYP2C19 variants with decreased enzyme activity led to lower levels of the active clopidogrel metabolite, resulting in a decreased inhibition of platelets and a higher rate of cardiovascular events when compared to noncarriers of the DNA variant. clopidogrel 140-151 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 58-65 19934793-3 2010 Several studies report that the genetic variation in CYP2C19 (*2) is associated

2009 From other studies, it was appreciated that the patients who had clopidogrel resistance had a defective allele *2/ in the CYP2C19 gene. clopidogrel 65-76 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 122-129 19246723-6 2009 Furthermore, there was a dose response evident in that the homozygotes CYP2C19*2/*2 had platelets that responded even less well to clopidogrel than the heterozygotes CYP2C19*2 that responded less well than the wild-type homozygote. clopidogrel 131-142 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 71-78 19246723-8 2009 However, the major

decreases by 24.30% +/- 11.66% (P = .032) in CYP2C19*1/*1. clopidogrel 6-17 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 182-189 19398604-8 2009 Clopidogrel inhibits CYP2C19-dependent hydroxylation of omeprazole in CYP2C19*1/*1 and has no impact on CYP3A4-catalyzed sulfoxidation of omeprazole. clopidogrel 0-11 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 21-28 19398604-8 2009 Clopidogrel inhibits CYP2C19-dependent hydroxylation of omeprazole in CYP2C19*1/*1 and has no impact on CYP3A4-catalyzed sulfoxidation of omeprazole. clopidogrel 0-11 cytochrome P450

apolipoprotein E Mus musculus 83-99 19323972-4 2009 Herein, we tested the hypothesis that clopidogrel will influence plaque size and composition in the atherosclerosis prone apolipoprotein E knockout (apoE KO) mouse model. clopidogrel 38-49 apolipoprotein E Mus musculus 122-138 19429918-9 2009 CONCLUSION: Variation in the gene encoding CYP2C19 in patients with stable CAD contributes to reduced exposure to clopidogrel"s active metabolite and a corresponding reduction in P2Y(12) inhibition, but has no significant influence on the response to prasugrel. clopidogrel 114-125 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 43-50 19452618-4 2009 There are various subgroups of acquired TTP associated with HIV infection, pregnancy, pancreatitis, associated with bone marrow

coagulation factor II, thrombin Homo sapiens 77-85 19618315-6 2009 RESULTS: Total amounts of thrombin markers produced at the site of injury were similar before and after addition of clopidogrel, whereas platelet release of sCD40L and P-selectin was lower during treatment with aspirin + clopidogrel by 33.8% and 27.8% (p < 0.001), respectively. clopidogrel 221-232 selectin P Homo sapiens 168-178 19618315-9 2009 CONCLUSION: Our study shows that clopidogrel combined with aspirin does not reduce thrombin formation following vascular injury, but attenuates platelet sCD40L and P-selectin release. clopidogrel 33-44 selectin P Homo sapiens 164-174 19440925-0 2009 Measurement of platelet P-selectin for remote testing of platelet function during treatment with clopidogrel and/or aspirin.

clopidogrel 22-33 coagulation factor II, thrombin Homo sapiens 98-106 17682072-3 2007 In this report, we describe the selectivity of 2-phenyl-2-(1-piperidinyl)propane (PPP) as an inactivator of CYP2B6 and compare this selectivity versus other CYP2B6 inactivators: 1,1",1""-phosphinothioylidynetrisaziridine (thioTEPA), clopidogrel, and ticlopidine. clopidogrel 233-244 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 108-114 18378613-3 2008 METHODS AND RESULTS: We measured ST2 at baseline in 1239 patients with ST-elevation myocardial infarction from the CLopidogrel as Adjunctive ReperfusIon TherapY-Thrombolysis in Myocardial Infarction 28 (CLARITY-TIMI 28) trial. clopidogrel 115-126 ST2 Homo sapiens 33-36 18398394-5 2008 Resistance to clopidogrel was determined by flow cytometry of intraplatelet vasodilator-stimulated phosphoprotein (VASP) phosphorylation. clopidogrel 14-25 vasodilator stimulated phosphoprotein Homo sapiens 76-113 18398394-5 2008 Resistance to clopidogrel was determined by flow cytometry of intraplatelet vasodilator-stimulated phosphoprotein (VASP) phosphorylation. clopidogrel 14-25 vasodilator stimulated phosphoprotein Homo sapiens 115-119 18393143-18 2008 The favorable clinical outcomes with aspirin and clopidogrel have validated cyclooxygenase (COX)-1 and P2Y (12) receptors as targets for new drug development. clopidogrel 49-60 mitochondrially encoded cytochrome c oxidase I Homo sapiens 76-98 18206732-3 2008 In a previous observational study, we found clopidogrel activity on platelets, tested by vasodilator-stimulated phosphoprotein (VASP) phosphorylation, to be diminished in patients receiving proton pump inhibitor (PPI) treatment. clopidogrel 44-55 vasodilator stimulated phosphoprotein Homo sapiens 89-126 18206732-3 2008 In a previous observational study, we found clopidogrel activity on platelets, tested by vasodilator-stimulated phosphoprotein (VASP) phosphorylation, to be diminished in patients

groups by measuring platelet phosphorylated-VASP expressed as a platelet reactivity index (PRI). clopidogrel 0-11 vasodilator stimulated phosphoprotein Homo sapiens 98-102 17989111-6 2008 alpha-Actin expression increased from control of 0.6 +/- 0.4% of mesangial area to 6.3 +/- 1.9% in ANG II-infused rats and this response was prevented by clopidogrel (0.4 +/- 0.2%) and PPADS. clopidogrel 154-165 angiogenin Rattus norvegicus 99-102 17989111-7 2008 The increase in AAWT from 4.7 +/- 0.1 to 6.0 +/- 0.1 mm in ANG II rats was also prevented by clopidogrel (4.8 +/- 0.1 mm) and PPADS. clopidogrel 93-104 angiogenin Rattus norvegicus 59-62 17989111-8 2008 ANG II infusion led to interstitial macrophage infiltration (105 +/- 16 vs. 62 +/- 4 cell/mm(2)) and tubular proliferation (71 +/- 15 vs. 20 +/- 4 cell/mm(2)) and these effects were prevented by clopidogrel (52 +/- 4 and 36 +/- 3 cell/mm(2)) and PPADS. clopidogrel 195-206 angiogenin Rattus norvegicus 0-3 18045851-6 2008 Rats that underwent five-sixths nephrectomy had higher markers of platelet activation (plasma GMP-140 and renal cortical fibrin deposition) than sham-operated rats, and clopidogrel attenuated these effects. clopidogrel 169-180 selectin P Rattus norvegicus 94-101 19544679-3 2008 Recent studies suggest that statins metabolized by CYP3A4 attenuate the anti-aggregatory effect of clopidogrel. clopidogrel 99-110 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 51-57 17631948-9 2008 CONCLUSION: To achieve sustained platelet P2Y12 inhibition in patients treated with cangrelor, clopidogrel administration should be started when the cangrelor infusion is terminated. clopidogrel 95-106 purinergic receptor P2Y12 Homo sapiens 42-47 17681590-2 2008 The second aim is to test the influence of

clopidogrel from 75 to 150 mg/day for 15 days in "low responders" is associated with a relative 20%-increase in its biological effect, independently of the CYP2C19 genotype, but without reaching the levels observed in "responders". clopidogrel 48-59 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 204-211 18217157-1 2008 Platelet inhibition as measured by vasodilator-stimulated

aggregation (MPA) decreased from approximately 79% to 10.8%, 42.7%, and 31.2%, with an overall VASP:MPA correlation of 0.88 (p < 0.01). clopidogrel 43-54 vasodilator stimulated phosphoprotein Homo sapiens 88-92 18217157-9 2008 VASP assay responses after the clopidogrel LDs showed a wider range of values (300 mg: 0-93%; 600 mg: 0-80%) than prasugrel (0-13%); MPA responses followed a similar trend. clopidogrel 31-42 vasodilator stimulated phosphoprotein Homo sapiens 0-4 18558425-0 2008 Clopidogrel pretreatment abolishes increase of PAI-1 after coronary stent implantation. clopidogrel 0-11

clopidogrel 12-23 serpin family E member 1 Homo sapiens 74-79 18941611-6 2008 Although 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors were initially suspected to decrease response to clopidogrel, later studies refuted this possibility. clopidogrel 127-138 3-hydroxy-3-methylglutaryl-CoA reductase Homo sapiens 9-66 17957565-7 2007 CONCLUSION: Modified TEG, employing

metabolized statins attenuate the antiaggregatory effect of clopidogrel. clopidogrel 114-125 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 28-53 15968399-9 2005 In PRP from stroke patients of older age, the P2Y(12)-mediated contribution to thrombin generation was variably reduced by two weeks of clopidogrel medication. clopidogrel 136-147 prion protein Homo sapiens 3-6 15933261-2 2005 We tested for an association of gene sequence variations in P2Y12 and occurrence of neurological adverse events in patients with symptomatic peripheral artery disease (PAD) during

affect PLA formation and probably the response to clopidogrel (which is known to reduce PLA-formation). clopidogrel 147-158 selectin P Homo sapiens 49-54 15968882-2 2005 Deficient variants (namely the Thr715Pro-SNP for CD62p and a VNTR-polymorphism for PSGL-1) might affect PLA formation and probably the response to clopidogrel (which is known to reduce PLA-formation). clopidogrel 147-158 selectin P ligand Homo sapiens 83-89 15817818-9 2005 CONCLUSIONS: VASP phosphorylation assays are reliable for quantifying clopidogrel effects. clopidogrel 70-81 vasodilator stimulated phosphoprotein Homo sapiens 13-17 15817818-10 2005 Because the VASP assay directly measures the function of the clopidogrel target, the P2Y12 receptor, the assay is selective for clopidogrel effects rather than effects of other platelet inhibitors commonly in use. clopidogrel 61-72 vasodilator stimulated phosphoprotein Homo sapiens 12-16 15817818-10 2005 Because the VASP assay directly measures the function of the

hydroxylation, a probe reaction for cytochrome P450 (CYP) 2B6 activity. clopidogrel 76-87 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 173-198 15961986-8 2005 CONCLUSIONS: Both clopidogrel and ticlopidine significantly inhibited the CYP2B6-catalyzed bupropion hydroxylation. clopidogrel 18-29 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 74-80 15961986-9 2005 Patients receiving either clopidogrel or ticlopidine are likely to require dose adjustments when treated with drugs primarily metabolized by CYP2B6. clopidogrel 26-37 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 141-147 15968399-9 2005 In PRP from stroke patients of older age, the P2Y(12)-mediated contribution to thrombin generation was variably reduced by two weeks of clopidogrel medication. clopidogrel 136-147 coagulation factor II, thrombin Homo sapiens 79-87 15795539-3 2005 The aim of this study was to test in patients (n = 416) scheduled for coronary artery stenting whether P2Y12 haplotype H2 carriage is associated with increased ADP-induced platelet aggregation after administration of a 600 mg loading dose of clopidogrel. clopidogrel 242-253 purinergic receptor P2Y12 Homo sapiens 103-108 15885609-2 2005 There is a significant variability of responsiveness among individuals towards clopidogrel, which is a specific inhibitor of the low-affinity human purinergic receptor (P2Y12). clopidogrel 79-90 purinergic receptor P2Y12 Homo sapiens 169-174 15609386-7 2005 RESULTS: Within 12 h of the loading dose, platelet activation in the clopidogrel group had decreased (P-selectin by 27.3 per cent, P = 0.017; fibrinogen binding by 34.7 per cent, P = 0.024; stimulated fibrinogen binding by 49.2 per cent, P < 0.001). clopidogrel 69-80 selectin P Homo sapiens 102-112 15816504-3 2005 However, the agents currently on the market (ticlopidine and clopidogrel), or known to be in development (cangrelor, AZD-6140 and prasugrel), all target the P2Y12 receptor. clopidogrel 61-72 purinergic receptor P2Y, G-protein coupled 12 Mus musculus 157-162 15816504-4 2005 The thienopyridines (ticlopidine, clopidogrel and prasugrel) irreversibly inactivate the P2Y12 receptor via the covalent binding of an active metabolite generated in the liver, while the other compounds are competitive antagonists. clopidogrel 34-45 purinergic receptor P2Y, G-protein coupled 12 Mus musculus 89-94 15823862-3 2005 We aimed to investigate the effects of clopidogrel ex vivo and another ADP-antagonist, AR-C69931MX in vitro on thrombin receptor activating peptide (TRAP)-induced platelet aggregation, procoagulant activity, microparticle formation and [Ca(2+)]i responses in patients with ACS. clopidogrel 39-50 TRAP Homo sapiens 149-153 15823862-5 2005 Clopidogrel (300 mg loading dose plus 75 mg daily) significantly inhibited TRAP-induced aggregation, procoagulant activity (annexin V binding) and microparticle production (all P < 0.05) but not as extensively as AR-C69931MX (400 nmol/l). clopidogrel 0-11 TRAP Homo sapiens 75-79 15823862-6 2005 [Ca(2+)]i responses induced by a combination of TRAP and ADP designed to mimic the physiological effects of released ADP showed that clopidogrel partially and AR-C69931MX completely removed the ADP component of the [Ca(2+)]i responses (n = 6). clopidogrel 133-144 TRAP Homo sapiens 48-52 15679472-2 2005 Clopidogrel is an inactive prodrug, which requires activation by the cytochrome P450 3A4 system in order to exert its antiplatelet action. clopidogrel 0-11 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 69-88 15679472-4 2005 From a theoretical point of view, a clinical relevant interaction may exist between clopidogrel and cytochrome P450 3A4 metabolized statins. clopidogrel 84-95 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 100-119 15852218-5 2005 This receptor, the molecular target of the antithrombotic drug clopidogrel, is responsible for most of the potentiating effects of ADP when platelets are stimulated by agents such as thrombin, collagen, or immune complexes. clopidogrel 63-74 coagulation factor II, thrombin Homo sapiens 183-191 15738352-10 2005 CONCLUSIONS: In elective stenting without clopidogrel pretreatment, use of a GPIIb/IIIa inhibitor produces superior platelet inhibition and lower myocardial necrosis compared with high-dose (600 mg) or standard-dose (300 mg) clopidogrel loading alone. clopidogrel 225-236 integrin subunit alpha 2b Homo sapiens 77-82 15726594-3 2005 Despite these in vitro and ex vivo findings, we observed two patients develop acute HIT while receiving both clopidogrel and aspirin: both patients" sera tested strongly positive in a heparin-dependent washed platelet activation assay (100% serotonin release) and PF4/heparin-enzyme-immunoassay (2.594 and 2.190 absorbance units). clopidogrel 109-120 platelet factor 4 Homo sapiens 264-267 15609386-7 2005 RESULTS: Within 12 h of the loading dose, platelet activation in the clopidogrel group had decreased (P-selectin by 27.3 per cent, P = 0.017; fibrinogen binding by 34.7 per cent, P = 0.024; stimulated fibrinogen binding by 49.2 per cent, P < 0.001). clopidogrel 69-80 fibrinogen beta chain Homo sapiens 142-152 15609386-7 2005 RESULTS: Within 12 h of the loading dose, platelet activation in the clopidogrel group had decreased (P-selectin by 27.3 per cent, P = 0.017; fibrinogen binding by 34.7 per cent, P = 0.024; stimulated fibrinogen binding by 49.2 per cent, P < 0.001). clopidogrel 69-80 fibrinogen beta chain Homo sapiens 201-211 15609386-9 2005 Platelet function in the clopidogrel group was significantly suppressed compared with baseline at 1 h, 24 h and 30 days after endovascular intervention (stimulated fibrinogen binding by 53.9, 51.7 and 57.2 per cent respectively; all P < 0.001). clopidogrel 25-36 fibrinogen beta chain Homo sapiens 164-174 15657204-6 2005 During hospital stay the typical course of clopidogrel associated TTP was observed with thrombocytopenia and petechial purpura occurring 14 days after drug initiation and prompt response to therapeutic plasma exchanges. clopidogrel 43-54 ZFP36 ring finger protein Homo sapiens 66-69 15816325-4 2005 VASP analysis is the most selective method for clopidogrel"s effect. clopidogrel 47-58 vasodilator stimulated phosphoprotein Homo sapiens 0-4 15604326-1 2005 OBJECTIVE: To assess a clinically significant interaction between cytochrome P450 3A4 (CYP3A4) metabolised statin and clopidogrel. clopidogrel 118-129 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 66-85 15782500-11 2005 Meanwhile, aspirin, clopidogrel, and their combination also decreased serum CRP (P < 0.05-0.01), without affecting lipid levels. clopidogrel 20-31 C-reactive protein Oryctolagus cuniculus 76-79 15813672-8 2005 In a mechanism possibly unrelated to its effect on platelet reactivity to aggregating stimuli, the presence of the PL(A2) allele might influence the antiaggregatory effect of platelet inhibitory drugs such as aspirin (acetylsalicylic acid), clopidogrel, and GPIIb/IIIa antagonists. clopidogrel 241-252 phospholipase A2 group IIA Homo sapiens 115-120 15604326-1 2005 OBJECTIVE: To assess a clinically significant interaction between cytochrome P450 3A4 (CYP3A4) metabolised statin and clopidogrel. clopidogrel 118-129 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 87-93 15604326-6 2005 MAIN OUTCOME MEASURE: Association of CYP3A4 metabolised statin and clopidogrel use with in-hospital and six month mortality. clopidogrel 67-78 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 37-43 15604326-9 2005 CONCLUSIONS: Use of a combination of a CYP3A4 statin plus clopidogrel was associated with lower six month mortality and morbidity in patients with acute coronary syndromes. clopidogrel 58-69 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 39-45 15634270-0 2005 Flow cytometric analysis of intraplatelet VASP phosphorylation for the

protein, is dependent on the level of activation of the platelet P2Y12 receptor, which is targeted by clopidogrel. clopidogrel 205-216 vasodilator stimulated phosphoprotein Homo sapiens 62-66 15634270-3 2005 The phosphorylation of vasodilator-stimulated phosphoprotein (VASP), an intraplatelet actin regulatory protein, is dependent on the level of activation of the platelet P2Y12 receptor, which is targeted by clopidogrel. clopidogrel 205-216 purinergic receptor P2Y12 Homo sapiens 168-173 15634270-4 2005 The aim of this study was to use a flow cytometric VASP phosphorylation assay to evaluate the efficacy of clopidogrel therapy. clopidogrel 106-117 vasodilator stimulated phosphoprotein Homo sapiens 51-55 15634270-9 2005 The flow cytometric analysis of VASP phosphorylation seems to be a suitable test to evaluate the efficacy of clopidogrel treatment. clopidogrel 109-120 vasodilator stimulated phosphoprotein Homo sapiens 32-36 16149027-7 2005 Via intracellular signaling, the adenosine diphosphate (ADP) receptor mechanism is closely involved in the activation of GPIIb/IIIa receptors so that also ADP receptor antagonists of the thienopyridine type, especially clopidogrel, can be quantitatively determined by the PADA. clopidogrel 219-230 integrin subunit alpha 2b Homo sapiens 121-126 15763887-6 2004 Clopidogrel significantly inhibited both ADP and TRAP-induced platelet responses over time, with steady state inhibition achieved by day 10. clopidogrel 0-11 TRAP Homo sapiens 49-53 15280513-9 2004 Statins, glitazones, glycoprotein IIb/IIIa inhibitors, and clopidogrel have been demonstrated to effectively reduce CD40L levels both in vitro and in vivo. clopidogrel 59-70 CD40 ligand Homo sapiens 116-121 15583724-2 2004 After metabolic activation, the active clopidogrel metabolite irreversibly impairs the human platelet P2Y12 ADP receptor. clopidogrel 39-50 purinergic receptor P2Y12 Homo sapiens 102-107 15583724-3 2004 Gialpha-protein activation and

and inhibition of vasodilator-stimulated phosphoprotein (VASP) phosphorylation are two key elements of the P2Y12 receptor pathway suitable for quantitation of clopidogrel effects. clopidogrel 186-197 purinergic receptor P2Y12 Homo sapiens 134-139 15583724-5 2004 We investigated clopidogrel effects in 57 patients after percutaneous coronary intervention and stent implantation by flow cytometry for the analysis of intracellular VASP phosphorylation. clopidogrel 16-27 vasodilator stimulated phosphoprotein Homo sapiens 167-171 15583724-9 2004 Comparable amounts of Gialpha and VASP were found in two clopidogrel low-responding patients as well as in two responding patients. clopidogrel 57-68 vasodilator stimulated phosphoprotein Homo sapiens 34-38 15583725-6 2004 Individual platelet activation determinations in patients receiving either clopidogrel or abciximab showed a variation in platelet activation as assayed by MPC and CD62P expression. clopidogrel 75-86 selectin P Homo sapiens 164-169 15550024-7 2004 Aspirin and clopidogrel were thus found to have similar effects on thrombotic variables and CRP in this patient population. clopidogrel 12-23 C-reactive protein Homo sapiens 92-95 15262828-9 2004 In both groups, 600 mg clopidogrel loading significantly inhibited ADP-induced expression of glycoprotein IIb/IIIa and P-selectin receptors. clopidogrel 23-34 selectin P Homo sapiens

p-selectin exposure was reduced by the atorvastatin pretreatment before clopidogrel was added. clopidogrel 181-192 selectin P Homo sapiens 109-119 15351859-6 2004 Combining clopidogrel with atorvastatin in the healthy individuals led to a further reduction in ADP-induced platelet p-selectin exposure. clopidogrel 10-21 selectin P Homo sapiens 118-128 15487851-6 2004 Clopidogrel has additional effects on the ADP-induced expression of adhesion molecules (P-selectin, GPIIb/IIIa) and inflammatory mediators (CD40L). clopidogrel 0-11 selectin P Homo sapiens 88-98 15487851-6 2004

sapiens 100-105 15487851-6 2004 Clopidogrel has additional effects on the ADP-induced expression of adhesion molecules (P-selectin, GPIIb/IIIa) and inflammatory mediators (CD40L). clopidogrel 0-11 CD40 ligand Homo sapiens 140-145 15291969-10 2004 CONCLUSIONS: The most interesting findings were the high mRNA expression of P2Y12 receptors in lymphocytes potentially explaining the anti-inflammatory effects of clopidogrel, P2Y13 receptors in monocytes and a previously unrecognised expression of P2X4 in lymphocytes and monocytes. clopidogrel 163-174 purinergic receptor P2Y12 Homo sapiens 76-81 15276105-0 2004 Effect of clopidogrel pretreatment on periprocedural rise in C-reactive protein after percutaneous coronary intervention. clopidogrel 10-21 C-reactive protein Homo

periprocedural increase in CRP by 65% and was independently associated with an attenuation in the CRP increase in a multivariate model. clopidogrel 0-11 C-reactive protein Homo sapiens 138-141 15269827-1 2004 The adenosine diphosphate (ADP) receptor P2Y12 blocking agent clopidogrel is clinically proven to be efficient in preventing thrombotic events. clopidogrel 62-73 purinergic receptor P2Y12 Homo sapiens 41-46 15205592-8 2004 In conclusion, the T allele of the GP Ia gene modulates platelet aggregation and clopidogrel antiplatelet effects, suggesting an enhanced reactivity to fibrillar collagens (exposed during coronary stenting) in T allele carriers and might contribute to an increased thrombotic risk in these patients. clopidogrel 81-92 multimerin 1 Homo sapiens 35-40 15156004-7 2004 Platelet aggregation, as well as P-selectin and PAC-1 expression were significantly lower in clopidogrel pre-treated patients at baseline (p<0.001) and at 4 hours (p<0.01), while they were similarly inhibited 24 hours after intervention. clopidogrel 93-104 selectin P Homo sapiens 33-43 15316304-1 2004 There has been recent concern regarding the potential for certain HMG CoA reductase inhibitors (statins) to interfere with the activation of clopidogrel, thereby leaving patients susceptible to thrombotic events. clopidogrel 141-152 3-hydroxy-3-methylglutaryl-CoA reductase Homo sapiens 66-83 15155956-8 2004 However, CD62p expression was significantly suppressed by aspirin treatment (P=0.024) and more substantially suppressed by clopidogrel (P<0.0001) on day 90.
