Acepromazine – Veterinary Sedative & Tranquilizer

Acepromazine is a phenothiazine derivative widely used in veterinary medicineaIt is valued for its rapid onset, reliable calming effect, and low toxicity. Unlike hypnotics, it does not induce deep sleep but instead produces tranquilization and muscle relaxation, making it ideal for pre‑anesthetic protocols and handling anxious animals.

Acepromazine Description

Acepromazine Maleate Injection is used for sedation, tranquilization and as a pre-anesthetic agent in horses, dogs and cats. Each ml contains 10 mg Acepromazine Maleate. Can be used as an aid in controlling animals during examination, treatment and minor surgical procedures. Maleate has a depressant effect on the central nervous system and therefore causes sedation, muscular relaxation and a reduction in spontaneous activity. It acts rapidly, exerting a prompt and pronounced calming effect. It is an effective pre-anesthetic agent and lowers the dosage requirement of general anesthetics.

Acepromazine Maleate Injection may be given intravenously, intramuscularly or subcutaneously. The general dosage of Maleate Injection for horses is 2-4 mg per 100 lbs body weight; dogs 0.25-0.5 mg per lb body weight; for cats 0.5-1.0 mg per lb body weight.

Not for use in animals hypersensitive (allergic) to it or other phenothiazines. Use with caution in debilitated or geriatric animals and those with liver or heart disease. Do not use in pregnant or lactating animals (female animals nursing their young) unless benefits outweigh the risks. Do not use in animals with hypovolemia (low blood volume), anemia, or shock. Do not use in animals with tetanus or strychnine toxicity. May cause seizures. Do not use with animals known to have seizures or are having medical procedures known to cause seizures (e.g., myelograms). When used to aid in restraint, the sedative effect can be overridden and the animal may bite or jump unexpectedly. Promace is an inappropriate medication for the treatment of aggression since it can make aggressive animals less predictable, and can interfere with training. Causes low blood pressure and inability to maintain proper bodytemperature.  ACEPROMAZINE ACEPROMAZINE ACEPROMAZINE ACEPROMAZINE
