[Effectiveness, tolerance and safety of simvastatin in comparison with bezafibrate in treatment of hypercholesterolemia].

The efficacy, tolerability and safety of simvastatin was compared to that of bezafibrate in a randomized placebo controlled double-blind trial including 64 patients with primary hypercholesterolemia with total cholesterol levels above 240 mg/dl and low-density lipoprotein (LDL) cholesterol above 195 mg/dl. During a placebo period of four weeks patients were counselled for a diet low in cholesterol (< 300 mg/day) and saturated fat (< 10% of calories). This period was also used for randomization of the individuals into the bezafibrate and simvastatin group, respectively. Patients assigned to bezafibrate treatment took bezafibrate at 600 mg/day throughout the entire 12 weeks of active treatment. Patients assigned to simvastatin took simvastatin at 10 mg/day when LDL-cholesterol was below 195 mg/dl, and at 20 mg/day when LDL-cholesterol was above 195 mg. To compare the lipid lowering effect of both substances total cholesterol, LDL- and high-density lipoprotein (HDL)-cholesterol were measured as well as triglycerides, very low density lipoprotein (VLDL)-cholesterol and the concentrations of apolipoproteins (apo)-AI, apo-AII and apo-B, respectively. These variables were compared between the two study groups with respect to the percentage change from baseline levels obtained during the placebo period. After a 12 week treatment period mean percent reduction of total cholesterol in the simvastatin group was 24% and that of LDL-cholesterol was 36%, both more pronounced than the respective reductions (14% and 17%) observed in the bezafibrate group. The mean percent increase in HDL-cholesterol was similar in both treatment groups (simvastation by 20% vs. bezafibrate by 17%).(ABSTRACT TRUNCATED AT 250 WORDS)
