Lack of Adverse Clopidogrel–Atorvastatin Clinical Interaction From Secondary Analysis of a Randomized, Placebo-Controlled Clopidogrel Trial

Abstract
Background— Statins primarily metabolized by cytochrome P450 3A4 (CYP3A4) reportedly reduce clopidogrel’s metabolism to active metabolite, thus attenuating its inhibition of platelet aggregation ex vivo. However, the clinical impact of this interaction has not been evaluated.
