MODE OF ACTION OF FIBRATES IN THE REGULATION OF TRIGLYCERIDE AND HDL-CHOLESTEROL METABOLISM

摘要

Epidemiological studies have shown that hyper-triglyceridemia and low HDL-cholesterol were both associated with an increased risk of coronary heart disease. Furthermore, hypertriglyceridemia is now recognized as an independent risk factor for coronary artery disease. Secondary prevention trials (e.g., LOCAT, BECAIT, BIP and DAIS) in coronary artery disease with drugs acting primarily on triglyc-erides (e.g., the PPAR-oc activators bezafibrate, fenofibrate and gemfibrozil) have shown that reducing triglycerides and increasing HDL-cholesterol, without significantly affecting LDL-cholesterol, slows down coronary artery luminal narrowing. Furthermore, the VA-HIT study recently showed that gemfibrozil decreased coronary artery disease mortality in secondary prevention trials, partly by increasing HDL-cholesterol.
