Dopamine antagonist

From Wikipedia, the free encyclopedia

A dopamine antagonist is a drug which blocks dopamine receptors by receptor antagonism. There are five types of dopamine receptors in the human body; they are found in the brain, peripheral nervous system, blood vessels, and the kidney).

[edit] Uses and examples

• Used as atypical antipsychotics (coupled with a serotonin antagonist): clozapine, risperidone, olanzapine, quetiapine, ziprasidone, aripiprazole

• Used as antiemetics: metoclopramide, droperidol, domperidone

• Used as tricyclic antidepressants: amoxapine
