Mechanism of action

Lovastatin competitively binds to HMG-CoA reductase and blocks the conversion of HMG-CoA to mevalonate, a critical early step in the cholesterol biosynthetic pathway. This leads to decreased intracellular cholesterol production, upregulation of LDL receptors on hepatocytes, and enhanced clearance of LDL cholesterol from the bloodstream. The net result is a significant reduction in serum LDL cholesterol and triglycerides.
