Metoclopramide hydrochloride hydrate

Metoclopramide hydrochloride hydrate (CAS No.: 54143-57-6) is a synthetic small molecule receptor modulator in the substituted benzamide class that is broadly categorized as a neurogastrointestinal pharmacology research tool for mechanistic studies of emesis and gastrointestinal motor regulation, with a functional profile characterized primarily by antagonism at dopamine D2 and serotonin 5 HT3 receptors and additional agonist like activity at serotonin 5 HT4 signaling systems, thereby supporting investigation of dopaminergic and serotonergic crosstalk in enteric neuronal circuits, vagal afferent pathways, and central emesis related networks; reported in vitro potency for D2 and 5 HT3 receptor inhibition is in the submicromolar to low micromolar domain, including representative nanomolar scale IC50 values, and this activity spectrum has made the compound useful in receptor pharmacology assays, pathway deconvolution experiments, and translationally oriented screening platforms that examine neurotransmitter dependent control of gastric emptying, intestinal transit, and stimulus induced nausea vomiting like phenotypes in preclinical systems, while typical concentrations in cell based assays and doses in animal studies are selected according to model context, target engagement requirements, and specific experimental objectives rather than fixed universal conditions, and overall it is most appropriately positioned as a reference antagonist scaffold for biomedical research, comparative profiling, and drug discovery workflows focused on dopamine serotonin axis biology.
