title: Effect of food on the pharmacodynamics and pharmacokinetics of atorvastatin, an inhibitor of HMG-CoA reductase.
abstract: The pharmacodynamics and pharmacokinetics of atorvastatin, an HMG-CoA reductase inhibitor, were characterized in 16 healthy subjects following administration of 10 mg atorvastatin tablets with, or 3 h after, evening meals for 15 days in an open-label, randomized, 2-way crossover study. Atorvastatin was well tolerated. Atorvastatin administration with evening meals resulted in 25.2% lower mean Cmax and 29.8% longer mean tmax values relative to administration after meals. The mean AUC(0-24) value was 8.6% lower for atorvastatin administration with meals compared to after meals. In contrast to the effect of food on pharmacokinetics, LDL-C reductions were similar after atorvastatin administration with or after evening meals. Average reductions from baseline were 24.4% for total cholesterol, 39.6% for LDL-C and 10% for triglycerides. Therefore, atorvastatin may be administered with or without food.
