The influence of CYP3A5*3 and BCRPC421A genetic polymorphisms on the pharmacokinetics of felodipine in healthy Chinese volunteers

摘要

What is known and objectiveThe role of CYP3A5 in drug metabolism has been receiving attention because CYP3A5 may be more involved in the metabolism of CYP3A substrates in vivo than previously thought. The polymorphism of transporters, such as P-gp (P-glycoprotein) and breast cancer-related protein (BCRP), influences the metabolism of these substrates, and felodipine is a substrate of P-gp. The aim of this study was to evaluate the pharmacogenetic variability in the disposition of felodipine in healthy Chinese subjects.
