Effects of atorvastatin metabolites on induction of drug‐metabolizing enzymes and membrane transporters through human pregnane X receptor

BACKGROUND AND PURPOSE Atorvastatin metabolites differ in their potential for drug interaction because of differential inhibition of drug‐metabolizing enzymes and transporters. We here investigate whether they exert differential effects on the induction of these genes via activation of pregnane X receptor (PXR) and constitutive androstane receptor (CAR).
