Pleiotropic effects of statins

The lipid-lowering actions of statins are well known. However, recent studies provide compelling evidence that the clinical benefits of statin therapy may also be attributed to mechanisms independent of their cholesterol-lowering effects. These non-lipid-lowering (pleiotropic) effects of statin therapy are believed to include antiinflammatory actions, property to reverse endothelial dysfunction by decreasing LDL oxidation and increasing nitric oxide bioavailability. Their antioxidant actions, ability to provide plaque stability, favorable coagulation profile, ability to prevent platelet aggregation and normalize sympathetic outflow as well as their antiproliferative and immunosuppressive properties also contribute to the non-lipid-lowering effects. These pleiotropic effects shown by statin therapy offer many advantages over the currently available drugs for dyslipidemias. These additional benefits not only find therapeutic application in cardiovascular disorders but also in many other disease states.
