Metopimazine
Based on 3 publication(s) in Google Scholar
Metopimazine (EXP999; RP9965) is a phenothiazine, orally available, selective dopamine D2 receptor antagonist that does not penetrate the blood-brain barrier. Metopimazine blocks dopamine D2 receptors in the chemoreceptor trigger zone and the periphery, thereby inhibiting nausea and vomiting. Metopimazine is indicated for chemotherapy-induced nausea and vomiting, and has low central side effects due to its poor brain penetration. The use of metopimazine in acute gastroenteritis may have potential risks.

Metopimazine (10 μM; 60 min) has a brain permeability of 69.72% in an in vitro blood-brain barrier model of bovine brain capillary endothelial cells (BCEC) co-cultured with glial cells, while its metabolite metopimazine acid has a permeability of only 15.72%, which is significantly lower than that of the dopamine receptor antagonist control group[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
