In Vitro Metabolism of Clebopride


Clebopride, a new drug, related to metoclopramide and sulpiride, was incubated with fortified 9000 g supernatant of liver homogenates of maleNzw rabbits.

A lactam,N-(4′-piperidyl-2′-one)-4-amino-5-chloro-2-methoxybenzamide, was identified as a metabolic product, using electron impact (low and high resolution) and field desorption mass spectrometry andCat proton magnetic resonance spectroscopy.
