Comparison of Micronized Fenofibrate and Pravastatin in Patients With Primary Hyperlipidemia

Abstract

Micronized fenofibrate lowers total cholesterol and low-density lipoprotein cholesterol to a similar extent as statins but raises high-density lipoprotein cholesterol and lowers triglycerides to a greater extent. The comparative lipid-modifying efficacy of micronized fenofibrate and pravastatin has not been evaluated in dyslipidemic patients. This prospective, multicenter, randomized trial compared the efficacy of 3 months' treatment with micronized fenofibrate (200 mg once daily) or pravastatin (20 mg once daily) in hypercholesterolemic type IIa and mixed dyslipidemic type IIb patients. Two hundred sixty-five male and female patients (18-75 years) were recruited from 28 European centers, and 151 were analyzed. Micronized fenofibrate was at least as effective as pravastatin in reducing levels of low-density lipoprotein cholesterol and total cholesterol in primary dyslipidemia but was significantly more effective than pravastatin in raising high-density lipoprotein cholesterol (respectively, 13.2% vs. 5.6%; p = 0.0084) and lowering triglycerides (-38.7% vs. -11.8%; p = 0.0001). In type IIa dyslipidemia, micronized fenofibrate was as effective as pravastatin in raising high-density lipoprotein cholesterol (+8.6% vs. +8.0%) but was fivefold more effective in lowering triglycerides (-34.3% vs. -7.2%; p = 0.0001). In type IIb dyslipidemic patients with low baseline high-density lipoprotein cholesterol levels, micronized fenofibrate was 10-fold and nearly 3-fold superior to pravastatin in raising high-density lipoprotein cholesterol and lowering triglycerides, respectively. Micronized fenofibrate may be considered an effective first-line therapy for patients with primary hyperlipidemia, particularly those with type IIb mixed dyslipidemia or type 2 diabetes.
