Is ethnic variability in the exposure to rosuvastatin explained only by genetic polymorphisms in OATP1B1 and BCRP or should the contribution of intrinsic ethnic differences in OATP1B1 be considered?

It is widely known that there is an approximately 2-fold higher exposure to rosuvastatin in Asian subjects compared with Caucasian controls. 1, 2 My group published a report in 2013 indicating that the ethnic variability in the plasma exposure to statins cannot be fully explained by the difference in the allele frequencies of organic anion transporting polypeptide (OATP) 1B1 and breast cancer resistance protein (BCRP), and suggesting that the intrinsic ethnic variability in the activity of OATP1B1 (the ratio of activity between Japanese and Caucasians is 0.584) must be considered. 3 This analysis based on the extended clearance concept was performed using many published clinical observations on ethnic variability in the pharmacokinetics of statins including rosuvastatin. 3 In this special issue of the Journal of Pharmaceutical Sciences, Wu et al. 4 published a paper entitled “Rosuvastatin pharmacokinetics in Asian and White subjects wild type for both OATP1B1 and BCRP under control and inhibited conditions” which concluded that polymorphisms in both OATP1B1 and BCRP are better predictors of rosuvastatin exposure than ethnicity alone. This conclusion was drawn from their clinical study, a 2-arm, randomized, cross-over rosuvastatin pharmacokinetics study in healthy White and Asian volunteers, which showed that rosuvastatin exposure in Asians and Whites did not differ significantly when all subjects were carriers of the wild-type alleles of both transporters. Therefore, our study 3 and that by Wu et al. 4 appear to have reached different conclusions. How can we interpret these apparent differences? The purpose of this commentary is to propose some possible explanations for the differences.
