Effects of simvastatin and probucol in hypercholesterolemia (Simvastatin Multicenter Study Group II).
This 12-week, randomized, double-blind, multicenter study compared the efficacy, tolerability and safety of simvastatin (a potent HMG-CoA reductase inhibitor) and probucol. Two doses of simvastatin, 20 or 40 mg once daily, were compared to probucol, 500 mg twice daily. Both simvastatin doses were significantly more effective than probucol in improving the plasma lipid profile. Mean reduction in low density lipoprotein (LDL) cholesterol was 34% with 20-mg simvastatin and 40% with the 40-mg dosage, compared to a mean reduction of 8% with probucol. Simvastatin significantly decreased total cholesterol, triglycerides and apolipo-protein B, and increased high density lipoprotein (HDL) cholesterol and apolipoprotein A-I. Probucol caused some reduction in LDL cholesterol but significantly decreased HDL cholesterol. Both simvastatin and probucol were well tolerated and no serious drug-related events occurred. Simvastatin appears to be a well-tolerated and effective new agent used once-a-day as an adjunct to diet in the management of patients with hypercholesterolemia.
