Lowsterol 5 Tablet contains Rosuvastatin 5 mg, a potent lipid-lowering agent belonging to the statin class of medications. It is primarily indicated for the treatment of hypercholesterolemia and mixed dyslipidemia to reduce elevated total cholesterol, low-density lipoprotein cholesterol (LDL-C), apolipoprotein B, and triglycerides, while increasing high-density lipoprotein cholesterol (HDL-C). Rosuvastatin acts by selectively inhibiting HMG-CoA reductase, the rate-limiting enzyme in cholesterol biosynthesis, leading to decreased cholesterol production in the liver and increased clearance of LDL from the bloodstream. Lowsterol 5 is used as an adjunct to diet and lifestyle modifications in patients with primary hyperlipidemia or mixed dyslipidemia and is also effective in reducing the risk of cardiovascular events in patients with multiple risk factors for atherosclerotic cardiovascular disease. The 5 mg dosage is suitable for patients requiring moderate lipid reduction or those initiating therapy. Common adverse effects may include headache, myalgia, abdominal pain, and nausea. Liver function tests and creatine kinase levels should be monitored periodically during therapy. Lowsterol 5 should be used with caution in patients with hepatic impairment or a history of muscle disorders and is contraindicated during pregnancy and lactation.
