Xylazine concentrations remained above the LOQ in the majority of horses at 48 hours and were still quantifiable in one horse at 96 hours. Serum concentrations of xylazine are expressed as the mean, median, and range at 48- and 72- hours post-administration (Table 1.1).

How long does xylazine last horses?

1. Following injection of Rompun® (xylazine injection), the animal should be allowed to rest quietly until the full effect has been reached. These dosages produce sedation which is usually maintained for 1 to 2 hours, and analgesia which lasts for 15 to 30 minutes.

Can xylazine cause seizures in horses?

Xylazine in stressed animals may activate al-adrenoceptors, resulting to central neural system excitement and seizures. Moreover, xylazine may had sensitized the myocardium to endogenous catecholamines, resulting to cardiac arrhythmias, cerebral hypoxia and seizures.

Is xylazine reversible?

Xylazine’s sedative effect—and its undesirable side effects of bradycardia, hypotension, and poor tissue perfusion—can be reversed by administration of α₂ antagonists, such as atipamezole or yohimbine.

What is xylazine toxicity?

Xylazine is a veterinary sedative, analgesic or general anesthetic. Its pharmaceutical action results in sympathetic discharge via stimulation of alpha-2-adrenoceptors. In humans, toxicity consists of central nervous system depression, bradycardia and hypotension.
