Crevast 20 mg (Rosuvastatin) is a statin medication used to lower high cholesterol (LDL & triglycerides), reduce the risk of serious cardiovascular events like heart attacks, strokes, and angina, and slow the buildup of plaque in arteries (atherosclerosis) by inhibiting cholesterol production in the body, often combined with diet and lifestyle changes. Variations like Crevast A or CV may also contain aspirin for added clot prevention.
