Abstract

Fenofibrate is a third-generation fibric acid derivative indicated as a monotherapy to reduce elevated low-density lipoprotein cholesterol, total cholesterol, triglycerides, and apolipoprotein B; to increase high-density lipoprotein cholesterol in patients with primary hyperlipidemia or mixed dyslipidemia; and to reduce triglycerides in patients with severe hypertriglyceridemia. In this review, the key characteristics of available fenofibrate formulations are examined. A literature search was conducted, focusing on comparative studies examining bioavailability, food effects, absorption, and lipid efficacy. Fenofibrate is highly lipophilic, virtually insoluble in water, and poorly absorbed. Coadministration with meals was necessary to maximize bioavailability of early formulations. Micronized and nanoparticle formulations of fenofibrate with reduced particle sizes were developed, resulting in greater solubility, improved bioavailability, and in some cases, the ability to be given irrespective of food. A recently introduced hydrophilic choline salt of fenofibric acid also can be taken without regard to meals, is absorbed throughout the gastrointestinal tract, has the highest bioavailability among marketed formulations, and is approved for coadministration with a statin. Differences in bioavailability of fenofibrate formulations have resulted in low-dose (40 - 67) mg and standard-dose (120 - 200 mg) formulations. Different formulations are not equivalent on a milligram-to-milligram basis. In order to prevent medication errors, resulting in underdosing or overdosing with attendant consequences, it is important for healthcare providers to recognize that the formulations of fenofibrate and fenofibric acid that are currently available vary substantially in relation to food effect, equivalency on a milligram-to-milligram basis, and indication to be coadministered with a statin.
