Influence of CYP2D6 Phenotypes on the Pharmacokinetics of Aripiprazole and Dehydro-Aripiprazole Using a Physiologically Based Pharmacokinetic Approach

Clin Pharmacokinet. 2021 Dec;60(12):1569-1582. doi: 10.1007/s40262-021-01041-x. Epub 2021 Jun 14. ABSTRACT BACKGROUND AND OBJECTIVES: Aripiprazole is an atypical antipsychotic drug that is metabolized by cytochrome P450 (CYP) 2D6 and CYP3A4, which mainly form its active metabolite dehydro-aripiprazole. Because of the genetic polymorphism of CYP2D6, plasma concentrations are highly variable between different phenotypes. In this study,…
