Quizplus · Accepted Answer

Dopamine antagonists are commonly used to treat nausea and vomiting as they block the dopamine receptors in the brainstem. Prochlorperazine, thiethylperazine, and metoclopramide are all dopamine antagonists that can be used for this purpose. Ondansetron, on the other hand, is a serotonin antagonist and hydroxyzine is an antihistamine, both of which are used for different types of nausea and vomiting.
