Temocaprilat was i.v. infused to experimental animals. The plasma concentration and the biliary excretion rate were determined under the steady-state condition. At the end of the experiments, the liver was removed to determine the concentration of temocaprilat. Results are mean ± S.E. of three independent experiments.
