Actions and Spectrum:Â
Action:Â
Sedative: Acepromazine acts on the central nervous system by depressing certain brain functions. It has a calming effect on animals, reducing anxiety and excitability.Â
Tranquilizer: It produces a state of relaxation and decreased responsiveness to external stimuli.Â
Antiemetic: Acepromazine can help prevent vomiting, making it useful for animals that are prone to motion sickness or experiencing nausea.Â
Spectrum:Â
Sedation: It is employed to calm animals during veterinary procedures, such as examinations, grooming, and minor surgeries.Â
Behavioral issues: Acepromazine can be used to manage certain behavioral problems in animals, such as aggression, anxiety, and hyperactivity.Â
Frequency not defined Â
FeverÂ
Extreme sleepinessÂ
Dry mouthÂ
Difficulty swallowingÂ
Difficulty breathingÂ
ConvulsionsÂ
ComaÂ
AgitationÂ
Black Box Warning:Â Â
None
Contraindication/Caution:Â Â
Hypersensitivity or Allergic Reactions: Animals that have previously shown hypersensitivity or allergic reactions to acepromazine or other phenothiazine derivatives should not receive this medication.Â
Animals with Severe Heart Conditions: Acepromazine can cause a decrease in blood pressure, which might be dangerous for animals with pre-existing cardiovascular conditions, including severe heart disease, shock, or low blood pressure.Â
Animals prone to Seizures: Acepromazine can lower the seizure threshold and may provoke seizures in animals that are prone to such episodes.Â
Debilitated or Shocked Animals: Acepromazine’s potential to cause hypotension (low blood pressure) makes it unsuitable for use in animals that are severely debilitated or in a state of shock.Â
Breeding, Pregnancy, and Nursing Animals: Acepromazine’s effects on the reproductive system of breeding, pregnant, or nursing animals are not entirely understood, so caution is advised when considering its use in such cases.Â
Pregnancy warnings:    Â
Pregnancy category: N/AÂ
Lactation: Excreted into human milk is unknownÂ
Pregnancy Categories:        Â
Category A: Studies that were well-controlled and met expectations revealed no risk to the fetus in either the first or second trimester.Â
Category B: There were a lack of studies on pregnant women and no evidence of risk to the fetus in animal experiments.  Â
Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.   Â
Category D: adequate data with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.  Â
Category X: Drugs listed in this category outweigh the risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.   Â
Category N: There is no data available for the drug under this category
Pharmacology: Acepromazine is a phenothiazine derivative primarily used as a veterinary sedative, tranquilizer, and pre-anesthetic medication for animals.Â
Pharmacodynamics:Â Â
Dopamine Receptor Antagonism: Acepromazine primarily acts as a dopamine receptor antagonist, specifically blocking dopamine D2 receptors in the central nervous system. By antagonizing these receptors, it inhibits dopamine-mediated neurotransmission, resulting in sedation and tranquilization. Â
Pharmacokinetics:Â
AbsorptionÂ
Acepromazine is well absorbed after oral, intramuscular, or intravenous administration in animals.Â
DistributionÂ
It has a high degree of protein binding and is distributed widely throughout the body, including the brain.Â
MetabolismÂ
The liver is primarily responsible for the process of metabolism, where it undergoes extensive metabolism through various pathways, including oxidation and conjugation.Â
Excretion and EliminationÂ
The metabolites and some unchanged drug are excreted mainly through the kidneys.Â
Administration: Â
Oral: Administered by mixing the appropriate dosage of acepromazine with food or directly into the animal’s mouth.Â
Intramuscular (IM): Administered via injection into the muscle. This route allows for a slower but more sustained release of the medication.Â
Intravenous (IV): Administered directly into the bloodstream. This route results in a rapid onset of action.Â

Generic Name: acepromazineÂ
Why do we use acepromazine? Â
Acepromazine is often used to calm and sedate animals, especially during veterinary examinations, grooming, minor procedures, and travel. It helps reduce anxiety, fear, and aggression in animals.Â
It is frequently used as a pre-anesthetic agent in combination with other drugs to prepare animals for surgery. It can help in reducing the amount of general anesthesia needed during procedures.Â
Acepromazine can be used to alleviate motion sickness and anxiety associated with car rides, travel, or other stressful situations for pets.Â
