| Compound Description | Ursodeoxycholic acid is a bile acid found in the bile of bears as a conjugate with taurine. Used therapeutically, it prevents the synthesis and absorption of cholesterol and can lead to the dissolution of gallstones. It has a role as a human metabolite and a mouse metabolite. It is a bile acid, a dihydroxy-5beta-cholanic acid and a C24-steroid. It is a conjugate acid of an ursodeoxycholate.Ursodeoxycholic acid , also known as ursodiol, is a naturally-occurring bile acid that constitutes a minor fraction of the human bile acid pool. UDCA has been used to treat liver disease for decades: its first use in traditional medicine dates back more than a hundred years. UDCA was first characterized in the bile of the Chinese black bear and is formed by 7b-epimerization of [chenodeoxycholic acid], which is a primary bile acid. Due to its hydrophilicity, UDCA is less toxic than [cholic acid] or [chenodeoxycholic acid]. UDCA was first approved by the FDA in 1987 for dissolution of gallstones and for primary biliary cirrhosis in 1996. UDCA works by replacing the hydrophobic or more toxic bile acids from the bile acid pool.Ursodiol is a Bile Acid.Ursodeoxycholic acid or ursodiol is a naturally occurring bile acid that is used dissolve cholesterol gall stones and to treat cholestatic forms of liver diseases including primary biliary cirrhosis. Ursodiol has been linked to rare instances of transient and mild serum aminotransferase elevations during therapy and to rare instances of jaundice and worsening of liver disease in patients with preexisting cirrhosis.Ursodeoxycholic acid has been reported in Myocastor coypus with data available.Ursodiol is a synthetically-derived form of ursodiol, a bile acid produced by the liver and secreted and stored in the gallbladder. Also produced by the Chinese black bear liver, ursodiol has been used in the treatment of liver disease for centuries. This agent dissolves or prevents cholesterol gallstones by blocking hepatic cholesterol production and decreasing bile cholesterol. Ursodiol also reduces the absorption of cholesterol from the intestinal tract.An epimer of chenodeoxycholic acid. It is a mammalian bile acid found first in the bear and is apparently either a precursor or a product of chenodeoxycholate. Its administration changes the composition of bile and may dissolve gallstones. It is used as a cholagogue and choleretic.See also: Dimethicone; pancrelipase; ursodiol . |
