Abstract
It is well known that the drug-mediated induction of cytochrome P450s (CYPs) has an important role in clinical drug-drug interactions (DDI). In addition, the DDI guidance issued by the U.S. Food and Drug Administration (FDA) suggests evaluating the induction potency of drugs on transporters, however, the evaluation is not performed frequently. Thus, we evaluated the induction and inhibition potency of CYP3A4 and organic anion transporting polypeptide (OATP) 1B1/1B3, that are induced by the same nuclear receptor, using various drugs related to DDI of CYP3A4 and OATP1B1/1B3…
