Acepromazine or Acetylpromazine (More commonly known as ACP, Ace, or by the trade name Atravet or "Acezine 2" etc, number depending on mg/ml dose) is one of the
phenothiazine derivative
psychotropic drugs, used little in humans, however frequently in animals as a
sedative and
antiemetic. Its principal value is in quietening and calming frightened and aggressive animals. The standard pharmaceutical preparation, acepromazine maleate, is used extensively in equine, feline, and canine; especially as a pre-anesthetic agent often in conjunction with
Atropine, and often an opiate such as
morphine or
buprenorphine. Its depressive cardiopulmonary effects can be profound and as such is not recommended for use in geriatric or debilitated animals, (often substituted with Midazolam in these cases, or left out of the premed cocktail all together).
