Pharmacological action

Exhol - hepatoprotective agent, has a choleretic effect. 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 reactions in the liver: 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

Hepatoprotective agent also has choleretic, cholelitholytic, hypolipidemic, hypocholesterolemic and some immunomodulatory effects. Having high polar properties, ursodeoxycholic acid (UDCA) forms non-toxic mixed micelles with apolar (toxic) bile acids, which reduces the ability of gastric reflux to damage cell membranes with biliary reflux gastritis and reflux esophagitis. In addition, UDCA forms binary molecules capable of being incorporated into the cellmembranes of hepatocytes, cholangiocytes, gastrointestinal epithelial cells, stabilize them and make them immune to the action of cytotoxic micelles. By reducing the concentration of bile acids toxic to the liver cell and stimulating bicarbonate-rich choleresis, UDCA effectively helps resolve intrahepatic cholestasis. Reduces the saturation of bile with cholesterol due to the inhibition of its absorption in the intestine, suppression of synthesis in the liver and lower secretion into bile, increases the solubility of cholesterol in bile, forming liquid crystals with it reduces the lithogenic index of bile. The result is the dissolution of cholesterol gallstones and the prevention of the formation of new calculi. The immunostimulating effect is due to including inhibition of the expression of HLA-1 antigens on hepatocyte membranes and HLA-2 on cholangiocytes, normalization of the natural killer activity of lymphocytes. Significantly delays the progression of fibrosis in patients with primary biliary cirrhosis, cystic fibrosis and alcoholic steatohepatitis reduces the risk of varicose veins of the esophagus. UDCA slows down the processes of premature aging and cell death (including hepatocytes, cholangiocytes).

UDCA is absorbed in the small intestine due to passive diffusion (about 90%), and in the ileum through active transport. Cmax in blood plasma when ingested 50 mg after 30, 60, 90 min - 3.8, 5.5 and 3.7 mmol / l, respectively. Tmax - 1-3 hours. Communication with plasma proteins is high - up to 96–99%. Penetrates through the placental barrier. With systematic administration, UDCA becomes the main bile acid in the blood serum and makes up about 48% of the total amount of bile acids in the blood. The therapeutic effect of the drug depends on the concentration of UDCA in bile. It is metabolized in the liver (clearance during the initial passage through the liver) into taurine and glycine conjugates. The resulting conjugates are secreted into the bile. About 50–70% of the total dose of the drug is excreted by bile. A small amount of non-absorbable UDCA enters the large intestine, where it is digested by bacteria (7-dehydroxylation), the resulting lithocholic acid is partially absorbed from the colon, but is sulfated in the liver and rapidly excreted as a sulfolitocholylglycine or sulfolithocholyltaurin conjugate.

children under 3 years of age.

Caution: children aged 3-4 years, as difficulty swallowing capsules.

Use during pregnancy and lactation

Women of childbearing age are advised to use non-hormonal contraceptives during the period of use of the drug.

The use of UDCA during pregnancy is only possible if the expected benefit to the mother outweighs the potential risk to the fetus. There are currently no data on the allocation of UDCA with breast milk.

If necessary, the use of UDCA during lactation should decide on the termination of breastfeeding.

Special instructions

For successful dissolution, it is necessary that the stones be pure cholesterol, no larger than 15-20 mm in size, the gall bladder is filled with stones no more than half and the bile ducts fully retain their function.

When prescribed for the purpose of dissolving gallstones, it is necessary to control the activity of hepatic transaminases and alkaline phosphatase (ALP), gamma-glutamintransferase (GGT), and bilirubin concentration. Cholecystography should be performed every 4 weeks in the first 3 months of treatment, then every 3 months. Monitoring the effectiveness of treatment is carried out every 6 months during an ultrasound during the first year of therapy.

While maintaining elevated levels, the drug should be discontinued. After the stones are completely dissolved, it is recommended to continue using them for at least 3 months, in order to facilitate the dissolution of stone residues, the sizes of which are too small for their detection and for the prevention of recurrence of stone formation. If, within 6-12 months after the start of therapy, partial dissolution of stones did not occur, it is unlikely that the treatment will be effective. Detection of non-visualizable gallbladder during treatment is evidence that complete dissolution of stones did not occur and treatment should be discontinued.
