By use of chromatographic methods, up to 25 metabolites in hydrolyzed and nonhydrolyzed urine have been detected. All four species produced the same main metabolites, as indicated by thin-layer chromatography. These, isolated from urine of the three animal species, were identified as N-(4{\textquoteright}-piperidyl)-2-methoxy-4-amino-5-chlorobenzamide, N-(4{\textquoteright}-piperidyl-2{\textquoteright}-one)-2-methoxy-4-amino-5-chlorobenzamide, and N-(1{\textquoteright}-alpha-hydroxybenzyl-4{\textquoteright}-piperidyl)-2-methoxy-4-amino-5-chlorobenzamide (tentative structure of a carbinolamine more stable than expected). In the dog, 2-methoxy-4-amino-5-chlorobenzoic acid was also detected. N4-glucuronidation of clebopride and some of its metabolites has been shown to occur in the three animal species. The rabbit produced large amounts of these conjugates. Clebopride N4-sulfonate was not present in the urine of any of the species investigated.}, issn = {0090-9556}, URL = {https://dmd.aspetjournals.org/content/8/2/87}, eprint = {https://dmd.aspetjournals.org/content/8/2/87.full.pdf}, journal = {Drug Metabolism and Disposition} }
