Droperidol vs. haloperidol in the initial management of acutely agitated patients.

In a double-blind clinical study, 27 acutely agitated patients were treated with an intramuscular injection of 5 mg of droperidol or 5 mg of haloperidol from identical appearing vials. At 30 minutes following treatment, 81% of the patients treated with haloperidol but only 36% treated with droperidol required a second injection (p less than .05). Thus, droperidol, a safe butyrophenone neuroleptic, appears to be a drug of choice for rapid and reliable control of acute agitation.
