Anti-gallstones drugs: Bile Acids

Ursodil 300 mg is a naturally occurring bile acid used to treat different hepatobilliary disorders. The activity of Ursodil 300 mg is achieved through a decrease in secretion of cholesterol in bile. Ursodil 300 mg 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. Ursodil 300 mg also promotes the formation of liquid cholesterol crystal complexes which enhance removal of the cholesterol from the gallbladder into the intestine to be expelled. Ursodil 300 mg improves cholestatic liver diseases by- Protecting cholangiocytes against cytotoxicity of hydrophobic bile acids Stimulating hepatobilliary secretion Protecting hepatocytes against bile acid-induced apoptosis Ursodil 300 mg 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 Ursodil 300 mg 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 Ursodil 300 mg appear in the circulation and very small amounts are excreted into urine. The biologic half life of Ursodil 300 mg ranges from 3.5-5.8 days.

Dissolution of Gall stones: 8-12 mg/kg/day either as single night time dose or in divided dosesPBC: 10-15 mg/kg/day in 2-4 divided dosesAcute Viral Hepatitis: 600 mg/dayAlcoholic Fatty Liver: 300 mg/dayPSC: 25-30 mg/kg/dayNASH: 13-15 mg/kg/day

Ursodil 300 mg 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.
