Used primarily in anesthesia and intensive care settings to prevent and treat nausea and vomiting, especially postoperative nausea. Also employed as a sedative and antiemetic in acute psychiatric settings due to its antipsychotic properties. Commonly administered in combination with opioids for balanced anesthesia to enhance sedation and reduce side effects. Its potent dopamine-blocking action makes it effective in managing agitation and delirium, though use is limited by potential cardiac side effects.
