Which pharmacological agent is commonly used to manage acute agitation in psychotic patients?

Haloperidol is a typical antipsychotic medication that is frequently used to manage acute agitation, particularly in patients experiencing psychosis. Its effectiveness in rapid sedation and controlling agitation makes it a preferred choice in emergency situations. When administered, haloperidol can quickly alleviate symptoms associated with psychotic episodes, such as severe agitation or aggression. This is crucial in emergency medical settings where patient safety and stabilization are priorities.

The most common alternative agents mentioned in the other choices, such as fluoxetine, lithium, and amitriptyline, are not typically used for immediate management of acute agitation. Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) used primarily for depression and anxiety disorders, lithium is a mood stabilizer mainly used for bipolar disorder, and amitriptyline is a tricyclic antidepressant. None of these agents address acute agitation effectively or rapidly, which is why they are not the usual choice in these circumstances.
