Ursodeoksikholevy acid has high polar properties and creates the non-toxic mixed micelles with toxic bile acids. It leads to the fact that ability of a gastric reflyuktat to damage cellular membranes at emergence a reflux esophagitis and biliary a reflux gastritis decreases. In addition drug Ursosan creates the double molecules entering cellular membranes of hepatocytes, epithelial cells of a gastrointestinal tract, holangiotsit. These molecules stabilize them and do unreceptive to influence of cytotoxic micelles.

Active agent of medicine also reduces the content of bile acids which are toxic for hepatocytes, and stimulates the cholepoiesis saturated with bicarbonates. Thanks to it the cholestasia disappears intra hepatic. Ursodeoksikholevy acid reduces a litogenny index of bile and concentration of cholesterol by means of preventing to its absorption in intestines, reduction of secretion in bile, oppressions of synthesis in a liver.
