Antigall Tablet

Antigall is a naturally occurring bile acid used to treat different hepatobilliary disorders. The activity of Antigall is achieved through a decrease in secretion of cholesterol in bile. Antigall achieves this through a few mechanisms: it reduces cholesterol absorption, suppresses liver cholesterol synthesis and it does not inhibit bile acid synthesis.

Therefore, alters bile composition from supersaturated to unsaturated. Antigall also promotes the formation of liquid cholesterol crystal complexes which enhance removal of the cholesterol from the gallbladder into the intestine to be expelled. Antigall improves cholestatic liver diseases by-

  • Protecting cholangiocytes against cytotoxicity of hydrophobic bile acids
  • Stimulating hepatobilliary secretion
  • Protecting hepatocytes against bile acid-induced apoptosis

Antigall is completely absorbed in the upper intestine. Time to peak serum concentration varies from 30 to 150 minutes. The rate of absorption ranges from 60-80%. After absorption Antigall enters the portal vein and undergoes extraction from portal blood by liver where it is conjugated with amino acid & that may be either glycine or taurine and then secreted into the hepatic bile ducts. Small quantities of Antigall appear in the circulation and very small amounts are excreted into urine. The biologic half life of Antigall ranges from 3.5-5.8 days.


Antigall is used for the treatment of Cholestasis (Jaundice), Viral Hepatitis, Alcoholic Fatty Liver, Primary Billiary Cirrhosis (PBC), Primary Sclerosing Cholangitis (PSC), Dissolution of Gallstones and Non-Alcoholic Steato Hepatitis (NASH).

Ursodeoxycholic acid is used to reduce the cholesterol saturation of bile and to promote the dissolution of gallstones. The cholesterol saturation of bile is reduced by Ursodeoxycholic acid, allowing gradual solubilization of cholesterol gallstones. Cholesterol of secretion into bile is reduced and bile acid secretion rate is increased during Ursodeoxycholic acid treatment without a reduction in phospholipids.

Antigall is also used to associated treatment for these conditions: Primary Biliary Cholangitis, Gallstone formation

It should be used cautiously in those with liver disease.


Antigall should not be used with drugs, such as oestrogenic hormones, that increase bile cholesterol. Concomitant administration with bile-acid binding drugs including antacids, charcoal and cholestyramine should be avoided, since this may reduce the effectiveness of therapy with Ursodeoxycholic acid.
