Dopamine receptor antagonists. As peripheral and central dopaminergic receptors are rather similar, the specificity of action of an antagonist on peripheral or central receptors depends primarily on its pharmacokinetic features.opamine has an emetic effect and inhibitis digestive motricity; its antagonists have antiemetic and digestive motility stimulant effects. Dopaminergic receptors in the chemoreceptor trigger zone responsible for vomiting are accessible to dopaminergic antagonists which do not cross the blood-brain barrier.
