Ezetimibe and fenofibrate combination therapy for mixed hyperlipidemia.

The ezetimibe and fenofibrate combination regimen was recently approved by the U.S. Food and Drug Administration for treatment of mixed hyperlipidemia. This powerful lipid-modifying therapy takes advantage of the different mechanisms of action of the two individual components. Ezetimibe selectively inhibits intestinal uptake of dietary and biliary cholesterol, and exerts its effect most notably on the low-density lipoprotein cholesterol (LDL-C). Fenofibrate activates the peroxisome proliferators-activated receptor alpha (PPAR-alpha), thereby increasing the tissue lipoprotein lipase activity and breakdown of triglycerides in very low-density lipoproteins (VLDL). The combination therapy of ezetimibe and fenofibrate has an excellent safety profile and exhibits potent synergistic actions on multiple lipid risk factors and represents another alternative in the clinical management of mixed hyperlipidemia. Further studies are needed to determine the effectiveness and safety of the ezetimibe and fenofibrate combination therapy used in conjunction with other lipid-modifying agents such as statins. Finally, outcome trials are warranted to evaluate if combination therapy would result in additive effects on morbidity and mortality. c 2007 Prous Science. All rights reserved.
