[Dose-effects studies with bezafibrate in patients with hypercholesterolemia and hypertriglyceridemia (author's transl)].

The dose-effect relationship of bezafibrate, a new clofibrate derivative, was investigated in 24 outpatients with a primary hyperlipidemia and a Type lla lipoprotein pattern. The patients were divided into two groups at random and in each case received 3 X 50, 3 X 100, 3 X 150 and 3 X 200 mg bezafibrate daily in increasing or falling dosage for four weeks. For rising doses a statistically significant dose-effect relationship could be demonstrated for cholesterol and triglycerides. This was only true for cholesterol with falling doses while triglycerides remained at a low level. The optimal dose was found to be 600 mg bezafibrate daily. The substance was well tolerated, and the usual laboratory parameters remained within the normal range in all patients.
