Ursodeoxycholic acid (UDCA) is a secondary bile acid formed via epimerization of chenodeoxycholic acid (CDCA; Item No. 10011286).1,2 UDCA is also a metabolite of lithocholic acid (LCA; Item No. 20253) in human liver microsomes.3 It inhibits taurocholic acid (Item No. 16215) uptake in HeLa cells expressing recombinant sodium/taurocholate cotransporting polypeptide (NTCP) with an IC50 value of 3.6 μM.4 UDCA (50 μM) inhibits apoptosis induced by deoxycholic acid (DCA; Item Nos. 20756 | 18231) or ethanol in primary rat hepatocytes.5 Dietary administration of UDCA blocks DCA-induced increases in the number of TUNEL-positive hepatocytes in rats. Formulations containing UDCA have been used in the treatment of primary biliary cirrhosis.WARNING This product is not for human or veterinary use.
