Grinterol capsules Pharmacotherapeutic group
Drugs used to treat the liver and biliary tract. Drugs used in biliary pathology. ATX code A05A A02.

Drugs used in liver diseases, lipotropic substances. ATX code A05B.

Pharmacodynamics
A significant amount of ursodeoxycholic acid has been found in human bile.

After ingestion, it reduces the saturation of bile with cholesterol, suppressing its absorption in the intestine and decreasing the secretion of cholesterol into bile. Perhaps due to the dispersion of cholesterol and the formation of liquid crystals, a gradual dissolution of gallstones occurs.

According to modern data, it is believed that the effect of ursodeoxycholic acid in liver diseases and cholestasis is due to the relative replacement of lipophilic, detergent-like toxic bile acids with hydrophilic cytoprotective non-toxic ursodeoxycholic acid, an improvement in the secretory capacity of hepatocytes and immunoregulatory processes.

Application for children

Cystic fibrosis

The use of ursodeoxycholic acid can reduce proliferation in the bile ducts, stop the progression of histological changes and even eliminate hepatobiliary changes, provided that therapy is started in the early stages of cystic fibrosis. For greater efficiency, treatment with ursodeoxycholic acid should be started immediately after the diagnosis of cystic fibrosis is clarified.

Pharmacokinetics
When administered orally, ursodeoxycholic acid is rapidly absorbed in the small and upper ileum by passive transport, and in the terminal ileum by active transport. The absorption rate is usually 60-80%. In the liver, bile acid undergoes almost complete conjugation with the amino acids glycine and taurine and is then excreted in the bile. The clearance of the first passage through the liver is up to 60%.

Depending on the daily dose and the underlying liver disorder or condition, the more hydrophilic ursodeoxycholic acid accumulates in the bile. At the same time, a relative decrease in the amount of other more lipophilic bile acids is observed.

Under the influence of intestinal bacteria, there is a partial degradation to 7-ketolithocholic and lithocholic acids. Lithocholic acid is hepatotoxic and causes damage to the liver parenchyma in some animal species. In humans, only a small amount of it is absorbed, which is sulfated in the liver and thus detoxified before being excreted in the bile and finally in the feces.

The biological half-life of ursodeoxycholic acid is 3.5 – 5.8 days.

Indications
Dissolution of X-ray negative cholesterol gallstones no more than 15 mm in diameter in patients with a functioning gallbladder, despite the presence of gallstone (s) in it.

Treatment of hepatobiliary disorders in cystic fibrosis in children aged 6 to 18 years.

Contraindications
Hypersensitivity to any substance that is part of the drug.

Acute inflammation of the gallbladder or bile ducts.

Obstruction of the bile ducts (blockage of the common bile duct or bladder duct).

Frequent episodes of hepatic colic.

Radiopaque calcified gallbladder stones.

Violation of the contractility of the gallbladder.

Poor result of portoenterostomy or lack of adequate biliary outflow in children with biliary atresia.
