Urso is the brand name for Ursodeoxycholic acid, a bile acid used to treat certain liver conditions. It works by reducing the production and secretion of cholesterol, a key component of bile. By altering the composition of bile, Urso helps dissolve small cholesterol stones and improve bile flow. The medication also exerts anti-inflammatory effects that protect liver cells from injury. Ursodeoxycholic acid is absorbed in the intestine and then transported to the liver where it integrates into bile. There it modulates bile acid sensors and decreases the synthesis of new bile acids, leading to lower cholesterol saturation. Through these actions it alleviates symptoms such as itching and improves liver function tests. Overall, Urso provides a targeted pharmacological approach to manage cholestatic liver disease without directly altering immune responses.

Urso is a synthetic formulation of Ursodeoxycholic acid used to treat specific liver disorders such as primary biliary cholangitis. It lowers hepatic cholesterol synthesis and stimulates bile flow, which helps dissolve small cholesterol stones in the bile. The drug acts by activating nuclear receptors that regulate bile acid production and transport across liver cells. These actions reduce the concentration of toxic bile acids and protect liver tissue from damage. Urso is taken orally and is absorbed in the gastrointestinal tract to reach the liver where it exerts its therapeutic effect. Its ability to modulate bile acid pathways differentiates it as a targeted therapy for certain cholestatic diseases.
