Xoten 20 Tablet contains Rosuvastatin 20 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 works 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. Xoten 20 is prescribed as part of a comprehensive management plan including diet, exercise, and lifestyle modifications to reduce the risk of cardiovascular events such as myocardial infarction, stroke, and angina in patients with atherosclerotic cardiovascular disease or those at high risk. The recommended dosage should be individualized based on patient response and lipid levels, with regular monitoring of liver function tests and lipid profiles. Caution is advised in patients with hepatic impairment, renal dysfunction, or a history of muscle disorders. Common adverse effects may include headache, myalgia, abdominal pain, and nausea. Patients should be advised to report any unexplained muscle pain or weakness promptly to prevent rare but serious complications such as rhabdomyolysis.
