The Role of OATP1B1 and BCRP in Pharmacokinetics and DDI of Novel Statins

Abstract

The aim of this review is to provide useful information not only for studying the effect of OATP1B1 and/or BCRP gene mutation on pharmacokinetics of novle statins of pitavastatin and rosuvastatin but also for studying drug-drug interactions (DDI) between the novle statins and other substrates of OATP1B1 and/or BCRP. Intra- and inter-ethnic differences in pharmacokinetic profiles of clinically relevant drugs are important issues reported in many papers not only for scenes of appropriate drug used in clinical settings but also for those of the drug development. Pharmacogenomics is extremely useful for understanding these racial differences. Recent pharmacogenetics study have disclosed important roles of drug transporters in the pharmacokinetic (PK) profiles of some clinically relevant drugs. In this presentation, we introduce single nucleotide polymorphisms (SNPs) of OATP1B1 and BCRP and review the contribution of genetic polymorphisms of the transporters to the pharmacokinetics of dual substrates as pitavastatin and rosuvastatin from recent study. At the same time, the DDIs between pitavastatin or rosuvastatin and other drug have been extensively concerned because of inhibiting OATP1B1-mediated hepatic uptake or BCRP-mediated hepatic efflux of pitavastatin and rosuvastatin. This review summarized the current studies about the role of OATP1B1 and BCRP in DDIs between pitavastatin or rosuvastatin and other clinically relevant drugs. The role of OATP1B1 and BCRP gene mutation can affect the PK profiles of pitavastatin and rosuvastatin. The DDIs between the novle statins and other substrates of OATP1B1 or BCRP may occur and cause change in the pharmacokinetic of the novle statins.
