1 Diltiazem augments the influence of MDR1 genotype status on cyclosporine concentration in Chinese patients with renal transplantation. Cyclosporine ATP binding cassette subfamily B member 1 Homo sapiens
2 In this study, we investigated how diltiazem altered the relationship between MDR1 genetic polymorphisms and CsA concentration in Chinese patients with renal transplantation. Cyclosporine ATP binding cassette subfamily B member 1 Homo sapiens
3 With regard to MDR1-3435, the adjusted CsA trough concentration was significantly higher in TT carriers than in CC and CT carriers when diltiazam was co-administered (58.83+-13.95 versus 46.14+-7.55 and 45.18+-12.35 ng/mL per mg/kg, P=0.011), and the differences were not observed in patients without diltiazam co-administered. Cyclosporine ATP binding cassette subfamily B member 1 Homo sapiens
4 With regard to MDR1-2677, the adjusted CsA trough concentration was significantly higher in TT carriers than in GG and GT carriers when diltiazam was co-administered (61.31+-12.93 versus 52.25+-7.83 and 39.70+-7.26 ng/mL per mg/kg, P=0.0001). Cyclosporine ATP binding cassette subfamily B member 1 Homo sapiens
5 CONCLUSION: MDR1 variants influence the adjusted CsA trough concentration in Chinese patients with renal transplant, and the influence more prominent when diltiazem is co-administered. Cyclosporine ATP binding cassette subfamily B member 1 Homo sapiens
