Gemfibrozil (Lopid), mechanism Of Action, Therapeutic Uses, Side Effects

Gemfibrozil (Lopid)
Mechanism Of Action:
Gemfibrozil (Lopid) stimulates the activity of peroxisome proliferating activating receptors (PPAR alpha), a class of nuclear receptor. Activation of these receptors alters the transcription of a number of genes involved in triglyceride metabolism including lipoprotein lipase and apolipoprotein CIII. This increases the peripheral catabolism (breakdown) of VLDL and chylomicrons, resulting in a reduction in the plasma concentration of VLDL, most notably in triglycerides, moreover, Gemfibrozil (Lopid) also reduce the synthesis of cholesterol, which further reduces plasma triglycerides.

Clinical and therapeutic uses:
a) Gemfibrozil (Lopid) can be used to treat hyperlipidemia of several etiologies, especially hypertriglyceridemia due to dysbetalipoproteinemia, a defect in apolipoprotein E that impairs clearance of chylomicron remnants and VLDL.
b) it is ineffective in primary chylomicronemia (caused by a deficiency in lipoprotein lipase).
c) it has antidiuretic action in individuals with mild to moderate diabetes insipidus
d) it is more effective than fenofibrate in some cases
