7-Ketolithocholic acid (3α-hydroxy-7-oxygen-5β-cholic acid) is a kind of bile acid, 7-Ketolithocholic acid can be absorbed, 7-ketolithocholic acid inhibits the production of endogenous bile acid, and can affect the secretion of biliary cholesterol[1,2].
After 7-ketolithocholic acid (400 mg/day) was administered orally for 14 days, biliary bile acid composition changed: The proportion of cholic acid decreased (from 45% to 19%), deoxycholic acid decreased (from 15% to 10%), chenodeoxycholic acid increased markedly (from 36% to 59%), ursodeoxycholic acid increased (from 36% to 59%), ursodeoxycholic acid increased (from 2% to 7%), and lithocholic acid increased (from 2% to 5%), while only trace amounts of 7-ketolithocholic acid were detected. During this treatment, the biliary lithogenic index fell from 2.6 to 0.9 and was accompanied by a pronounced drop in biliary cholesterol concentration[2].
