Tolazoline as a Reversal Agent for Wildlife
Tolazoline (Tolazine® in the branded form) is an alpha-adrenergic antagonist that is used primarily as a reversal agent for xylazine. Tolazoline is FDA-approved and indicated for the reversal of effects associated with xylazine in horses. . . Thus, it is often used to reverse sedation and cardiovascular effects of xylazine in ruminants. It has also been used for reversing alpha-agonists in a variety of other species, but less safety and efficacy data is available.
