Efficacy, safety and tolerability of lovastatin and bezafibrate retard in patients with hypercholesterolemia.

Hyperlipidemia has turned out to be the most important risk factor for coronary heart disease and necessitates frequently lipid lowering long-term treatment. Therefore, efficacy and tolerability of hypolipemic drugs are of great interest. The objective of the present study was to compare the safety, tolerability and effect on plasma lipids of Lovastatin and Bezafibrate retard in patients with hypercholesterolemia. 99 patients with total cholesterol of > or = 250 mg/dl after a 4 week standard lipid-lowering diet were treated another 4 weeks with placebo and then randomized to 400 mg Bezafibrate retard or 20 to 80 mg Lovastatin given once a day for 12 weeks. Mean changes from baseline in total cholesterol, LDL cholesterol and triglycerides were significantly reduced, in HDL cholesterol increased in both treatment-groups (p < or = 0.01). The effects of Lovastatin on total cholesterol and LDL cholesterol were more pronounced than those of Bezafibrate retard (p < or = 0.01), while Bezafibrate had a larger effect on triglycerides (p < or = 0.05). The frequency of clinical adverse experiences was low and similar among treatment groups, the frequency of laboratory adverse experiences was higher in the Lovastatin group. One patient in the Bezafibrate group was withdrawn because of nausea, one patient in the Lovastatin group because of GGT elevation.
