title: In vitro metabolism of lidoflazine by rat and dog liver fractions.
abstract: Lidoflazine was metabolized very rapidly by 16000 g supernatant fractions of rat and dog liver. The rate and the extent of metabolism were considerably superior for rat liver. Lidoflazine metabolites were purified by extraction and thin-layer chromatography and identified by mass spectrometry. The main pathways of the in vitro metabolism by rat and dog liver fractions were the same. Oxidative N-dealkylation was the most important. An incubation of major metabolite 1-[4,4-bis(4-fluorophenyl)-butyl]piperazine, with rat liver fraction was performed. A hydroxylated metabolite and a ketopiperazine metabolite were detected only in the dog experiments.
