Cerivastatin

Cerivastatin is a synthetic HMG-CoA reductase inhibitor with high liver selectivity, which lowers plasma cholesterol levels by inhibiting endogenous cholesterol synthesis. In vitro, the affinity of cerivastatin for HMG-CoA reductase was higher than that of lovastatin, simvastatin and pravastatin. This higher enzyme affinity was reflected in vivo, with a lower ED50 (dose causing 50% inhibition) for cerivastatin in rats and beagle dogs compared with lovastatin. Cerivastatin 0.2 mg/day significantly reduced low density lipoprotein (LDL)-cholesterol, total cholesterol and triglyceride levels, and increased high density lipoprotein (HDL)-cholesterol levels, in patients with type IIa hypercholesterolaemia. Available data indicate that cerivastatin has a tolerability profile similar to that of other HMG-CoA reductase inhibitors. No drug interactions were observed when cerivastatin was coadministered with digoxin, warfarin, cimetidine or the antacid magnesium/aluminium hydroxide.
