Concentration behavior of carbamazepine in bile and plasma of man. 1978

B Terhaag, and K Richter, and H Diettrich

The concentration in plasma and bile of carbamazepine was determined in four humans with Kerr's T-tube drain after an oral administration of a single dose of 400 mg of Finlepsin (carbamazepine). The mean plasma half-life time was 25 (15-31) hr. The concentration time curves in bile and plasma were parallel with the bile to plasma concentration ratio of 0.62 (0.24-0.82). A negative linear correlation between the lithogenic index and the bile plasma concentration ratio was found. It is suggested that the concentration of carbamazepine in bile is influenced by the saturation of biliary micelles with cholesterol. The amount of carbamazepine eliminated by bile within 72 hr was 4.1 +/- 1.9 mg, i.e., 1% of the administered dose. It is concluded that there is no significant enterohepatic circulation of carbamazepine.

D001646 Bile An emulsifying agent produced in the LIVER and secreted into the DUODENUM. Its composition includes BILE ACIDS AND SALTS; CHOLESTEROL; and ELECTROLYTES. It aids DIGESTION of fats in the duodenum. Biliary Sludge,Sludge, Biliary
D001647 Bile Acids and Salts Steroid acids and salts. The primary bile acids are derived from cholesterol in the liver and usually conjugated with glycine or taurine. The secondary bile acids are further modified by bacteria in the intestine. They play an important role in the digestion and absorption of fat. They have also been used pharmacologically, especially in the treatment of gallstones. Bile Acid,Bile Salt,Bile Salts,Bile Acids,Acid, Bile,Acids, Bile,Salt, Bile,Salts, Bile
