Metopimazine has antidopaminergic, antihistamine, and anticholinergic activity.[7] However, it has also been described as a highly potent and selective dopamine D2 and D3 receptor antagonist.[5] The D2 receptor antagonism of metopimazine is thought to underlie its antiemetic and gastroprokinetic effects.[5] It is said to not readily cross the blood–brain barrier and hence to have peripheral selectivity, in contrast to metoclopramide but similarly to domperidone.[5] Unlike domperidone however, metopimazine shows no hERG inhibition and hence is expected to have a more favorable cardiovascular profile.[5] In contrast to metoclopramide, metopimazine does not interact with serotonin 5-HT3 and 5-HT4 receptors.[5]
