Description
Domperidone maleate, a peripheral dopamine receptor antagonist, exerts its primary mechanism of action by blocking dopamine receptors in the chemoreceptor trigger zone (CTZ) and upper gastrointestinal tract. This blockage inhibits dopamine-induced nausea and vomiting by reducing gastrointestinal motility and enhancing gastric emptying. Domperidone selectively targets peripheral dopamine receptors, particularly D2 receptors, which leads to increased gastrointestinal motility and improved gastrointestinal symptoms.
