Description

Domperidone (R33812) monomaleate is an orally active and selective dopamine-2 receptor antagonist. Domperidone monomaleate acts as an antiemetic and a prokinetic agent through its effects on the chemoreceptor trigger zone and motor function of the stomach and small intestine.

Cardiac Na+ channels are common targets of therapeutics inducing cardiotoxicity[3].
Domperidone monomaleate (0-1000 μM) displays concentration- and state-dependent inhibitory of Nav1.5 in Human embryonic kidney HEK293 cells[3].
Domperidone monomaleate (0, 10, 100 μM) displays tonic and use-dependent block to Na currents in rat cardiomyocytes with a IC50 of 312 μM[3].

Unlike Metoclopramide, Domperidone monomaleate does not cause any adverse neurological symptoms as it has minimal penetration through the blood-brain barrier[1].
Domperidone monomaleate acts as both an antiemetic and an upper gastrointestinal tract prokinetic agent. It is rapidly absorbed after oral administration, and few side effects have been reported[2].
