Diltiazem 88-97 cytochrome P450, family 3, subfamily a, polypeptide 62 Rattus norvegicus 66-71 15681897-9 2004 However, ketoconazole and cyclosporin A, which are specific CYP3A inhibitors, inhibited the metabolic extraction of diltiazem (0.05 mM) by only about 20% at the concentration (40 microM) at which they inhibited CYP3A almost completely, suggesting that the contribution of CYP3A to intestinal diltiazem metabolism is not marked. Diltiazem 116-125 cytochrome P450, family 3, subfamily a, polypeptide 62 Rattus norvegicus 60-65 10454523-2 1999 In this study, we examined whether treatment with the calcium channel antagonists, nicardipine, nifedipine or diltiazem, alters cytochrome P-450 2B or 3A (CYP2B or CYP3A, respectively) expression in rat liver. Diltiazem 110-119 cytochrome P450, family 3, subfamily a, polypeptide 62 Rattus norvegicus 164-169 28766866-0 2017 Enhanced Oral Bioavailability of Diltiazem by the Influence of Gallic Acid and Ellagic Acid in Male Wistar Rats: Involvement of CYP3A and P-gp Inhibition. Diltiazem 33-42 cytochrome P450, family 3, subfamily a, polypeptide 62 Rattus norvegicus 128-133 28766866-8 2017 Gallic acid and ellagic acid significantly increased the bioavailability of diltiazem due to the inhibition of both CYP3A-mediated metabolism and P-glycoprotein-mediated efflux in the intestine and/or liver. Diltiazem 76-85 cytochrome P450, family 3, subfamily a, polypeptide 62 Rattus norvegicus 116-121 15681897-9 2004 However, ketoconazole and cyclosporin A, which are specific CYP3A inhibitors, inhibited the metabolic extraction of diltiazem (0.05 mM) by only about 20% at the concentration (40 microM) at which they inhibited CYP3A almost completely, suggesting that the contribution of CYP3A to intestinal diltiazem metabolism is not marked. Diltiazem 116-125 cytochrome P450, family 3, subfamily a, polypeptide 62 Rattus norvegicus 211-216 15681897-9 2004 However, ketoconazole and cyclosporin A, which are specific CYP3A inhibitors, inhibited the metabolic extraction of diltiazem (0.05 mM) by only about 20% at the concentration (40 microM) at which they inhibited CYP3A almost completely, suggesting that the contribution of CYP3A to intestinal diltiazem metabolism is not marked. Diltiazem 116-125 cytochrome P450, family 3, subfamily a, polypeptide 62 Rattus norvegicus 211-216 12951478-4 2003 The simultaneous addition of GBE to small intestine and liver microsomes inhibited the formation of N-demethyl DTZ (MA), an active metabolite of DTZ produced by CYP3A, in a concentration-dependent manner, with an IC(50) of about 50 and 182 microg/ml, respectively. Diltiazem 111-114 cytochrome P450, family 3, subfamily a, polypeptide 62 Rattus norvegicus 161-166 12951478-9 2003 These results indicated that the concomitant use of GBE in rats increased the bioavailability of DTZ by inhibiting both intestinal and hepatic metabolism, at least in part, via a mechanism-based inhibition for CYP3A. Diltiazem 97-100 cytochrome P450, family 3, subfamily a, polypeptide 62 Rattus norvegicus 210-215
