Droperidol, a butyrophenone, is a potent tranquilizer which produces in the patient a state of calm, disinclination to move, and "disconnection" from the surroundings. It has an  -adrenergic blocking effect, which offers some protection against shock, leads to good peripheral perfusion, and "unmasks" hypovolemia. It also protects against epinephrine-induced arrhythmias, and has an antiemetic effect.
Droperidol may cause hypotension by virtue of its -adrenergic blocking effect and peripheral vasodilatation, particularly when the drug is administered rapidly and in the presence of hypovolemia. The hypotension is usually transitory in the former case,
