Effects of fenofibrate on lipids, lipoproteins, and apolipoproteins in 33 subjects with primary hypercholesterolemia.
The effects of fenofibrate on lipids, lipoproteins, and apolipoproteins in 33 subjects with primary hypercholesterolemia were assessed in a 6-month parallel group study, placebo (n = 15) versus fenofibrate 300 mg/day (n = 18), followed by an open label 6-month treatment period. After stabilization on an isocaloric low fat (less than 35% total calories) diet with less than 250 mg cholesterol/day and a P/S ratio of 1, and maintenance of LDL-cholesterol (LDL-C) levels greater than or equal to 175 mg/dl, subjects received placebo for 6 weeks and were then randomized into placebo or fenofibrate groups for 6 months, followed by open label treatment for 6 months. During the 6-month double-blind period, compared to the placebo group, the treatment group had significant reductions in total cholesterol, LDL-C, total apo B, and triglyceride, and increments in HDL-cholesterol, apolipoprotein A-I and apolipoprotein A-II (P less than 0.01 for all comparisons). Compared to placebo baseline, therapy with fenofibrate resulted in a reduction of LDL-C, apo B, and the LDL-C/HDL-C ratio of 15%, 13%, and 18% respectively; HDL-C, apo A-I, and apo A-II increased respectively 12%, 13% and 30% (P less than 0.01 for all comparisons). Mean adherence during the double blind phase of the trial was 95% in the drug group and 96% in the placebo group. An additional 6 months of open label fenofibrate therapy maintained the reduced total and LDL-C as well as the elevated HDL-C, apo A-I and apo A-II in the drug-drug group.(ABSTRACT TRUNCATED AT 250 WORDS)
