In medicine, fibrates are antilipemic agents for treating hyperlipidemia. Fibrates lower triglycerides by being agonists of peroxisome proliferator-activated receptor alpha (PPAR alpha)[1] Examples include:

Clinical use

A systematic review of randomized controlled trials of fibrates concluded "In addition to improving lipid profiles, fibrates are associated with an important decrease in nonfatal myocardial infarction, but do not substantially affect all-cause mortality."[2]

Research in synergy

There has been interest in the synergistic use of alpha and gamma PPAR agonists. Trials with dual agonists, the glitazars, were stopped for safety reasons. [3] The PROactive trial had better results using a fibrate with a thiazolidinedione, pioglitazone, but the risk-benefit is not clear in patients with dyslipidemia and diabete. [4]
