Xarostat 10 Tablet contains Rosuvastatin 10 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), and triglycerides, while increasing high-density lipoprotein cholesterol (HDL-C). Rosuvastatin works by selectively inhibiting HMG-CoA reductase, the enzyme responsible for the rate-limiting step in cholesterol biosynthesis, thereby reducing cholesterol production in the liver and promoting increased clearance of LDL particles from the bloodstream. Xarostat 10 is prescribed to patients at risk of cardiovascular events, including those with atherosclerotic cardiovascular disease, familial hypercholesterolemia, or multiple risk factors for coronary heart disease. The medication is administered orally, typically once daily, with or without food. Common adverse effects may include headache, myalgia, abdominal pain, and nausea, while rare but serious side effects include myopathy and hepatotoxicity, necessitating periodic monitoring of liver function tests and creatine kinase levels. Xarostat 10 should be used cautiously in patients with pre-existing liver disease or renal impairment. It is contraindicated during pregnancy and lactation. Patient adherence to prescribed dosage and lifestyle modifications is essential for optimal therapeutic outcomes.
