Pharmacological action 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 in biliary reflux gastritis and 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.
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 to 50-75% (with daily doses of 10-20 mg / kg). Penetrates through the placental barrier.

For the treatment of biliary reflux gastritis, 1 measured spoon of Ursofalk is prescribed 1 time / day.The course of treatment is from 10-14 days to 6 months , if necessary – up to 2 years.
For the symptomatic treatment of primary biliary cirrhosis, the daily dose depends on body weight and ranges from 2 to 6 scoops (approximately 10-15 mg / kg body weight).
Diarrhea, nausea, pain in the epigastric region and right hypochondrium calcification of gallstones increased activity of hepatic transaminases (AST, ALT).
In the treatment of primary biliary cirrhosis, transient decompensation of cirrhosis of the liver may occur, which disappears after discontinuation of the drug.
Cholestyramine, colestipol and antacids containing aluminum hydroxide bind ursodeoxycholic acid in the intestine, interfere with its absorption and weaken effectiveness (simultaneous administration is impractical).
