Ursodeoxycholic Acid



This drug is indicated for the dissolution of small to medium sized radiolucent, cholesterol rich gall-stones in functioning gall bladders. This drug is also indicated for the treatment of primary biliary cirrhosis.



Ursodeoxycholic acid is a natural bile acid used to treat different liver and gallbladder diseases. The activity of ursodeoxycholic acid is achieved by reducing the secretion of cholesterol in the bile. Ursodeoxycholic acid achieves this through several mechanisms: it reduces the absorption of cholesterol, inhibits the synthesis of cholesterol in the liver, and does not inhibit the synthesis of bile acids.

Therefore, it changes the composition of bile from supersaturated to unsaturated. Ursodeoxycholic acid also promotes the formation of liquid cholesterol crystal complexes, thereby enhancing the excretion of cholesterol from the gallbladder to the intestine. Ursodeoxycholic acid improves cholestatic liver disease

Protects bile duct cells from the cytotoxicity of hydrophobic bile acids
Stimulates hepatobiliary secretion. Protects liver cells from bile acid-induced apoptosis

Ursodeoxycholic acid in the intestine The upper part is completely absorbed. The time to reach peak serum concentration ranges from 30 to 150 minutes. The absorption rate is between 60% and 80%. Ursodeoxycholic acid enters the portal vein after absorption, and is extracted from the portal vein blood through the liver, combined with amino acids, which can be glycine or taurine, and then secreted into the hepatobiliary ducts. A small amount of ursodeoxycholic acid appears in the circulation, and a very small amount is excreted in the urine. The biological half-life of ursodeoxycholic acid is 3.55.8 days.

This drug should not be administered with oral contraceptives, oestrogenic hormones and other drugs which reduce the blood cholesterol level and increase the bile cholesterol level.
Concomitant administration with bile acid-binding drugs including antacids, charcoal and cholestyramine should be avoided, since this may reduce the effectiveness of therapy with Ursodeoxycholic acid.



This medicine is contraindicated to radio-opaque calcified gall-stones, non-functioning gall bladder, inflammatory diseases and other conditions of the small intestine, colon and liver which interfere with the enterohepatic circulation of bile salts.
