Description

Urdoxa Pharmacodynamics
Hepatoprotective drug, has a choleretic effect. Reduces cholesterol synthesis in the liver, its absorption in the intestine and its concentration in bile, increases cholesterol solubility in the biliary system, stimulates bile formation and excretion. It decreases bile lithogenicity and increases bile acids content; it causes intensification of gastric and pancreatic secretion, increases lipase activity and has hypoglycemic effect. Causes partial or complete dissolution of cholesterol stones in enteral administration, reduces bile saturation with cholesterol, which promotes mobilization of cholesterol from gallstones. It has an immunomodulatory effect, affects immunological reactions in the liver: it reduces the expression of some antigens on the membrane of hepatocytes, affects the number of T-lymphocytes, interleukin-2 formation, reduces the number of eosinophils.
Cystic fibrosis (cystic fibrosis)
According to clinical reports, there is long-term experience (up to 10 years and more) of treating children with hepatobiliary disease associated with cystic fibrosis with ursodeoxycholic acid. There is evidence that therapy with ursodeoxycholic acid is able to reduce the proliferation of bile ducts, slow down the development of lesions detected by histological examination, and even contribute to the reversal of hepatobiliary changes in the case if the therapy is started at early stages of cystic fibrosis. In order to optimize the effectiveness of treatment, therapy with ursodeoxycholic acid should be started as early as possible after the diagnosis of cystic fibrosis is made.
