Pharmacological action of

Pharmacodynamics of

Having high polar properties, UDCA forms non-toxic mixed micelles with apolar (toxic) bile acids, which reduces the ability of refluxate to damage cell membranes during biliary reflux gastritis and reflux-reflux. In addition, UDCA forms binary molecules capable of being incorporated into cell membranes, stabilizing them and making them immune to cytotoxic micelles.

Reduces the saturation of bile with cholesterol by inhibiting its absorption in the intestine, inhibiting synthesis in the liver and lowering secretion into bile, increases the solubility of cholesterol in bile, forming liquid crystals with it, and decreases the lithogenic index of bile. The result is the dissolution of cholesterol gallstones and the prevention of the formation of new calculi.

The immunomodulatory effect is due to the inhibition of the expression of HLA antigens on the membranes of hepatocytes and cholangiocytes, the normalization of the natural killer activity of lymphocytes, etc. Reliably delays the progression of fibrosis in patients with primary biliary cirrhosis, cystic fibrosis and alcoholic steatohepatitis, and it reduces the risk of varicose vein hepatitis.

For successful dissolution of gallstones, it is necessary that the stones are purely cholesterol, their size does not exceed 15-20 mm, and the gallbladder (filled with stones no more than half) and bile ducts fully retain their function.

Pharmacokinetics

Absorbed in the jejunum due to passive diffusion, in the ileum - due to active transport. When administered in a single dose of 500 mg, the concentration in the blood serum after 30, 60 and 90 minutes is 3.8, 5.5 and 3.7 μmol / L, respectively.

With systematic administration, ursodeoxycholic acid (UDCA) becomes the main serum bile acid (48% of the total bile acid content). It is included in the system of enterohepatic circulation. The therapeutic efficacy of the drug depends on the concentration of UDCA in bile. During therapy, a dose-dependent increase in the proportion of UDCA in the bile acid pool up to 50-75% (with daily doses of 10-20 mg / kg). Penetrates through the placental barrier.
