title: Biliary elimination of apalcillin in cholecystectomized patients.
abstract: Pharmacokinetic examinations were performed in 5 patients with bile-duct drainage following cholecystectomy and choledochus revision with 2 g of apalcillin over 20 min intravenously. In comparison to healthy volunteers they had significantly longer half-life values and long persisting serum concentrations over a period of 24 h. The biliary elimination rate of apalcillin correlated with the hepatic function of the patients and was with 4.3% on the average distinctly lower than that of healthy volunteers, whereby the bile, however, could probably not be collected quantitatively in cases of open papilla. Compensatory excretion of apalcillin took place via the kidneys and, considering the metabolites A1 and A2, it amounted to a total of 73%.
