  • MetabollsmHepatic. The only common metabolite in these species is 2-[(4-amino-5-chloro-2-methoxybenzoyl)-aminolacetic acid. N-Deethylation is a major pathway for metoclopramide metabolism in the lower animals but not in humans. In humans, about one-half of the total radioactivity excreted was as a metoclopramide conjugates, indicating that this is a major route of excretion
