The active ingredient of URSODEX is Ursodeoxycholic Acid, a bile acid which is normally present in bile. Ursodeoxycholic acid is an epimer of chenodeoxycholic acid. Its administration changes the composition of bile and may dissolve gallstones. It is used as a cholagogue and choleretic.
Bile Acid Preparations/Anticholelithic Agent
Dose and Direction of Use
Take the medication as directed by your doctor and as mentioned on the label. Unless told differently, swallow the tablet with water.
Mode of Action
The mechanism of action of UDCA in liver and cholestasis disorders has not yet been explained totally. However, UDCA alters bile acid composition, resulting in increases in the concentration of UDCA and decreases in the concentrations of the more hydrophobic and potentially toxic bile acids, cholic and chenodeoxycholic acids. UDCA also has a choleretic effect, resulting in increased bile acid output and bile flow. There is some evidence for immunological effects, including a reduction of abnormal expression of HLA Class I antigens on hepatocytes and a suppression of immunoglobulin and cytokine production. The Ursodeoxycholic acid converts lithogenic bile in non-lithogenic bile and gradually dissolves the cholesterol gallstones.
