Effect of Ursodeoxycholic Acid on Biliary Bile Acid and Bile Lipid Composition in Gallstone Patients
Adolf Stiehl, Richard Raedsch, Gerda Rudolph, Siegfried Walker – 1 January 1984 – In five patients with radiolucent gallstones, the effect of ursodeoxycholic acid (Urso) in doses of 250, 500, 750, 1,000, and 1,250 mg per day on biliary lipid and bile acid composition was studied. Biliary cholesterol decreased from 8.8 ± 0.8 mole% to 4.4 ± 0.2 mole% at 500 mg Urso per day (7.1 mg per kg) and to 4.2 ± 0.3 mole% at 750 mg Urso per day (10.7 mg per kg). Administration of 1,000 or 1,250 mg Urso per day produced no further decrease of biliary cholesterol.
