Metabolite Identification
Common NameItopride
DescriptionItopride belongs to the class of organic compounds known as n-benzylbenzamides. N-benzylbenzamides are compounds containing a benzamide moiety that is N-linked to a benzyl group. Itopride is a very strong basic compound (based on its pKa). Higher acetylcholine increases GI peristalsis, increases the lower esophageal sphincter pressure, stimulates gastric motility, accelerates gastric emptying, and improves gastro-duodenal coordination. However, the dosage and details of administration may vary depending on the patient's age, symptoms, and other factors. Raising of prolactin levels is more common with high dose regimes of itopride. This compound has been identified in human blood as reported by (PMID: 31557052 ). Itopride is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Itopride is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
