1 Significant impacts of CYP3A4*1G and CYP3A5*3 genetic polymorphisms on the pharmacokinetics of diltiazem and its main metabolites in Chinese adult kidney transplant patients. Diltiazem cytochrome P450 family 3 subfamily A member 5 Homo sapiens
2 This study was carried out to investigate the impacts of the CYP3A4*1G and CYP3A5*3 genetic polymorphisms on the trough concentration/dose ratios and pharmacokinetics of diltiazem and its main metabolites in Chinese adult renal transplant patients. Diltiazem cytochrome P450 family 3 subfamily A member 5 Homo sapiens
3 RESULTS AND DISCUSSION: The dose-adjusted concentrations and pharmacokinetics of diltiazem and its main metabolites were significantly affected by CYP3A4 *1G and CYP3A5*3 alleles. Diltiazem cytochrome P450 family 3 subfamily A member 5 Homo sapiens
4 The dose-adjusted trough levels and AUC of diltiazem and its main metabolites were significantly lower in CYP3A5*1*1 carriers than in CYP3A5*3 carriers (P < 0 05). Diltiazem cytochrome P450 family 3 subfamily A member 5 Homo sapiens
5 The dose-adjusted trough levels and AUC of diltiazem and its main metabolites were significantly lower in CYP3A5*1*1 carriers than in CYP3A5*3 carriers (P < 0 05). Diltiazem cytochrome P450 family 3 subfamily A member 5 Homo sapiens
6 WHAT IS NEW AND CONCLUSION: The CYP3A4*1G and CYP3A5*3 genetic polymorphisms are closely related to the trough concentration/dose ratios and pharmacokinetics of diltiazem and its main metabolites in Chinese adult renal transplant patients. Diltiazem cytochrome P450 family 3 subfamily A member 5 Homo sapiens
