Ursodeoxycholic acid (ucda) is increasingly used for the treatment of cholestatic liver diseases. experimental evidence suggests three major mechanisms of action: (1) protection of cholangiocytes against cytotoxicity of hydrophobic bile acids, resulting from modulation of the composition of mixed phospholipidвђђrich micelles, reduction of bile core tip: ursodeoxycholic acid can be considered one of the less expensive, best tested and safest of the drugs currently available. this editorial is aimed to provide a brief review of the principal non-invasive non-surgical medical treatments for cholesterol gallstones.

Mechanism of action.вђ”the issue arises as to the mecha-nism of action for the lipid-lowering effect of udca. the authors describe a series of potential mechanisms for the beneficial effect of udca on the hyperlipidemia associated with primary biliary cirrhosis, including effects on hydroxymethylglutaryl-coenzyme a reductase, absorption of cholesterol, and the bile acid pool. the regression of ursodeoxycholic acid (udca) is the first choice medication for most cholestatic hepatopathies, due to its capability to counter act in- flammation and bile-acid-induced liver вђ¦
