Effects of ezetimibe on the pharmacodynamics and pharmacokinetics of lovastatin

Abstract

The co-administration of ezetimibe and lovastatin was well tolerated and resulted in a significantly greater percentage reduction in serum LDL-C concentrations than with lovastatin alone, with an average incremental reduction of 16-18%. Ezetimibe 10mg appears to be the optimal dose when co-administered with lovastatin 20mg once daily. Further incremental reductions in LDL-C from the co-administration of ezetimibe and lovastatin are expected only when the dose of lovastatin is increased. The co-administration of ezetimibe and lovastatin has the potential to produce clinically significant reductions in LDL-C compared to either drug alone, with favorable safety and tolerability.
