Plenoliv 300, developed by Plenum Biotech, is a 300 mg tablet containing ursodeoxycholic acid, a bile acid used to treat liver and gallbladder conditions. It is primarily prescribed for dissolving cholesterol-rich gallstones and managing primary biliary cirrhosis, a chronic liver disease. The medication works by reducing cholesterol production in the liver and enhancing bile flow, thereby improving liver function and preventing stone formation. Common side effects may include abdominal discomfort, diarrhea, nausea, itching, and rash. Plenoliv 300 is typically taken after meals with water or milk, and treatment duration may extend over several months, depending on the condition being treated.
