Grapefruit juice significantly increased serum concentrations of atorvastatin acid, atorvastatin lactone, and active and total HMG-CoA reductase inhibitors, probably by decreasing CYP3A4-mediated first-pass metabolism of atorvastatin in the small intestine. On the other hand, grapefruit juice had no effect on the pharmacokinetics of pravastatin. Concomitant use of atorvastatin and at least large amounts of grapefruit juice should be avoided, or the dose of atorvastatin should be reduced accordingly.
