Liveric® is a preparation Ursodeoxycholic Acid, one of the secondary bile acids. It is used to dissolve gallstones made of cholesterol and is the only USFDA approved drug to treat primary biliary cirrhosis.
Ursodeoxycholic acid is known to reduce cholesterol content of biliary fluid (produced by the liver and stored in the gall bladder for secretion into the intestine to digest fats) and also to reduce the absorption of cholesterol from the gut. Both of these actions decrease the amount of cholesterol that passes into the bile. Also, since Ursodeoxycholic Acid is a bile acid itself, it increases the level of bile acids within the bile. The combination of these two factors stops the cholesterol separating out of the bile. The gallstones then begin to dissolve. This is a useful alternative for people who cannot have, or wish to avoid surgery.
