Vatinoxan hydrochloride is primarily used in veterinary medicine as a selective alpha-2 adrenoceptor antagonist. It is often administered in combination with other drugs, such as medetomidine or dexmedetomidine, to mitigate the cardiovascular side effects associated with alpha-2 agonists. This combination helps maintain stable heart rate and blood pressure in animals during sedation or anesthesia, improving safety and efficacy. It is particularly valuable in large animals like horses and cattle, where cardiovascular stability is critical during medical procedures. Additionally, vatinoxan hydrochloride enhances the recovery process, allowing animals to return to normal function more quickly after sedation.
