In vivo binding taurine is present in bile acid is a hydrophilic, as a cholesterol gallstone dissolving agent. Can reduce the secretion of cholesterol the liver, reduce cholesterol saturation of bile, stimulates bile acids increase the solubility of cholesterol in the bile, cholesterol stones dissolve or prevent the formation of stones. Increase the secretion of bile, bile duct mouth sphincter relaxation produce gallbladder, it is conducive to the stones. This product can not dissolve other types of gallstones. Ursodeoxycholic acid useful in the treatment of cholesterol stones, hyperlipidemia, bile secretion disorders, primary biliary cirrhosis, chronic hepatitis, bile reflux gastritis and prevention of liver allograft rejection and reaction.
