Other animals

Promazine, given as promazine hydrochloride, is one of the primary tranquilizers used by veterinarians as a pre-anaesthesia injection in horses.[7][8] It does not provide analgesia and is not a very strong sedative, hence it is used combined with opioids or α2 adrenoreceptor agonists, such as clonidine, or both.[8][9] It can be used alone when performing a non-painful procedure such as the fitting a horseshoe.[9] Low blood pressure, fast heart rate and paralysis of the penis are side effects.[7] It is also an antiemetic, antispasmodic and hypothermic agent.[8] Additionally it is used to lower blood pressure in animals with laminitis and kidney failure.[8] It is available in the US for veterinary use under the names Promazine and Tranquazine.[citation needed]
