Pharmacological action

PHARMACOTHERAPEUTIC GROUP OF THE MEDICINAL PRODUCT:

Hepatoprotective agent

ATC CODE: [A05AA02]

Pharmacologic drug-resistant drug It reduces the synthesis of cholesterol in the liver, its absorption in the intestine and concentration in bile, increases the solubility of cholesterol in the biliary system, stimulates the formation and secretion of bile.

Reduces the lithogenicity of bile, increases the content of bile acids in it, causes an increase in gastric and pancreatic secretion, enhances lipase activity, has a hypoglycemic effect. Causes partial or complete dissolution of cholesterol stones during enteral use, reduces the saturation of bile with cholesterol, which helps mobilize cholesterol from gallstones.

It has an immunomodulatory effect, affects the immunological reaction in the liver: it reduces the expression of certain antigens on the hepatocyte membrane, affects the number of T-lymphocytes, the formation of interleukin-2, reduces the number of eosinophils.

Pharmacokinetics

Ursodeoxycholic acid (UDCA) is absorbed in the small intestine by passive diffusion (about 90%), and in the ileum by active transport. After oral administration in a single dose (500 mg), the maximum concentration in the blood serum (Cmax) after 30, 60, 90 min is 3.8, 5.5, 3.7 mmol / L, respectively. Communication with plasma proteins is high - up to 96-99%.

Crosses the placental barrier. With systematic administration, ursodeoxycholic acid becomes the main serum bile acid (48% of the total bile acid content). The therapeutic effect of the drug depends on the concentration of UDCA in bile.

Metabolized in the liver (clearance during the initial passage through the liver) to taurine and glycine conjugates. The resulting conjugates are secreted into the bile. About 50-70% of the total dose is excreted through the intestines. A small amount of non-absorbable ursodeoxycholic acid enters the large intestine, where it is digested by bacteria (7-dehydroxylation), the resulting lithocholic acid is partially absorbed from the colon, but sulfates in the liver and is rapidly excreted in the form of a sulfolithocholylglycine or sulfolithocholyltaurin conjugate.
