Ursodeoxycholic acid, marketed under the brand name Ursofalk, is a medication primarily used in the treatment of certain liver and gallbladder conditions. It is particularly effective in dissolving small, cholesterol-rich gallstones in patients who prefer not to undergo surgery, and in managing primary biliary cholangitis, a chronic disease that damages the bile ducts in the liver. Ursofalk works by reducing the production of cholesterol in the liver and by slowly dissolving the cholesterol that makes up the gallstones. It is also known for its ability to improve liver function tests in people with liver disease. Available in capsule and liquid forms, Ursofalk's use and dosage depend on the specific condition being treated and the patient's overall health profile.
