Pharmacology: Fenofibrate is phenoxyisobutyric acid. With clofibrate and other fibrate derivatives is used as lipid regulatory by reducing total plasma cholesterol and triglyceride in healthy subjects and patients with hyperlipoproteinemia. The main action of fenofibrate is to increase lipoprotein catabolism in patients with triglyceride-rich lipoprotein by increasing lipase lipoprotein activity.
