Pharmacodynamics and pharmacokinetics
The composition determines the effect of this medicine. Its active component is ursodeoxycholic acid . Ursodeoxycholic acid has high polar properties and creates non-toxic mixed micelles with toxic bile acids. This leads to a decrease in the ability of gastric reflux to damage cell membranes with the appearance of reflux esophagitis and biliary reflux gastritis . In addition, the drug Ursosan creates double molecules that enter the cell membranes of hepatocytes, epithelial cells of the gastrointestinal tract, and cholangiocytes. These molecules stabilize them and make them immune to the influence of cytotoxic micelles.
The active substance of the drug also reduces the content of bile acids, which are toxic to hepatocytes, and stimulates choleresis, saturated with bicarbonates. Thanks to this, intrahepatic cholestasis disappears. Ursodeoxycholic acid reduces the lithogenic index of bile and cholesterol by preventing its absorption in the intestine, reducing secretion in bile, and inhibiting synthesis in the liver. As a result, cholesterol gallstones dissolve. The product also prevents the appearance of new stones.
The drug acts as an immunomodulatory agent by inhibiting the expression of HLA-2 and HLA-1 and improving the normal killer activity of lymphocytes . In addition, it prevents the development of fibrosis in people with primary biliary cirrhosis , as well as alcoholic steatohepatitis and cystic fibrosis . Reduces the likelihood of varicose veins in the esophagus, slows down premature aging and cell death.
The active substance of the drug is absorbed from the small intestine by passive diffusion (absorption rate is approximately 90%), and in the ileum by active transport. The maximum concentration is reached after approximately 60-180 minutes.
The degree of binding to plasma proteins is up to 99%. With chronic use, ursodeoxycholic acid becomes the main bile acid in the blood serum. The therapeutic effect of the drug depends on its content in bile.
The drug is broken down in the liver with the formation of metabolic such as glycine and taurine conjugate. They are secreted into bile. Approximately 60% of the total dosage is excreted in bile. Some of the active substance is also transported to the colon, where it is broken down by bacteria. Lithocholic acid is absorbed to a small extent from the colon, sulfated in the liver and excreted as sulfolithocholylglycine or sulfolitocholyltaurine conjugate.
Effect of the drug
According to the study, it has been proven that ursodeoxycholic acid is quickly absorbed in the intestine and is integrated into liver cells and provides them with protection from various negative factors, including toxic and alcohol damage. When taking the medicine, congestion in the organ decreases and the removal of acids accelerates.
Ursosan, the instructions for use emphasize this, has a choleretic effect. The active substance is capable of:
- Reduce cholesterol production in the liver and slow down its absorption in the intestines.
- Reduce the saturation of bile with cholesterol.
- Increase the content of bile acids.
- Increase the solubility of cholesterol in the biliary system.
