Avaliação de Alfa 2 adrenoceptores associados ou não ao Butofarnol em equinos: revisão de literatura

Abstract

In many of the procedures carried out in the field in horses, sedation of the animal is required in view of its restless and often aggressive temperament. Within this context, drugs that allow sedation of the animal and maintenance in a quadrupedal position stand out, maintaining cardiorespiratory stability. Drugs belonging to the group of alpha2 adrenoceptor agonists have been widely used in this species for chemical restraint, sedation or even as analgesics, promoting much more pronounced muscle relaxation than other sedative agents. The use of xylazine, detomidine and romifidine in the equine species stands out in this group. In addition, the association of these drugs with butorphanol has been shown to be advantageous, providing adequate sedation and analgesia, without cardiorespiratory changes.
