Ursodeoxycholic acid Usage
1. Study finds that ursodeoxycholic acid can be used to prevent neocoronavirus infections, It reduces the number of cellular ACE-receptors on cells making it more difficult for viruses to enter human cells.
2. Ursodeoxycholic acid has a beneficial cholestatic effect as it increases the secretion of bile acids when it enters the patient’s body.
3. It also inhibits the synthesis of cholesterol in the liver, reducing the cholesterol and cholesterol esters contained in the bile. In addition, studies have shown that ursodeoxycholic acid can have an immunomodulatory effect when dealing with chronic liver diseases.
4. Ursodeoxycholic acid is useful for cholesterol reduction and stone dissolution, and can be used for the treatment of small stones in the gallbladder without surgery.
