What Is Ketamine for Horses?

Ketamine, also known as Ketamine Hydrochloride or Ketalar, is a potent anesthetic and analgesic drug commonly used in veterinary medicine for horses. It belongs to a class of medications called dissociative anesthetics, which produce a trance-like state, dissociation, and profound analgesia, while maintaining cardiovascular stability.

Ketamine was initially developed in the 1960s as an alternative to commonly used anesthetic agents at the time. Its unique properties make it an ideal choice for veterinary procedures, especially in horses, as they require specialized sedation and anesthesia due to their size and temperament.

The drug works by blocking certain receptors in the brain, primarily the N-methyl-D-aspartate (NMDA) receptors. This results in a dissociative state where the horse feels disconnected from its surroundings, reducing anxiety and sensitivity to pain. The analgesic effect of ketamine is particularly beneficial during surgeries, as it ensures that the horse remains comfortable while under anesthesia.

Ketamine is commonly used in horses for various procedures, such as dental work, wound repair, orthopedic surgeries, and diagnostic imaging. It is particularly useful in cases where the horse needs to be immobilized or remain still for an extended period. The drug’s sedative properties allow veterinarians to perform necessary procedures without causing distress to the horse, minimizing the risk of injury to both the animal and the handlers.
