Which alpha-adrenergic blocking agent is used as a reversal for xylazine? Trade Yobine.

• A. Tolazoline
• B. Yohimbine
• C. Naloxone
• D. Atipamezole

Answer: (B)

Xylazine sedates by activating alpha-2 receptors in the CNS, so reversing its effects requires an alpha-2 adrenergic receptor antagonist. Yohimbine is that antagonist and is sold under the trade name Yobine, making it the reversal agent associated with this brand. By blocking alpha-2 receptors, yohimbine quickly counteracts the sedative and analgesic effects of xylazine. Onset is rapid with appropriate administration, but there can be a surge in sympathetic activity as the drug wears off, leading to tachycardia or hypertension, so monitoring is important. Other options exist, but the product linked to the brand Yobine is Yohimbine, the alpha-2 antagonist used to reverse xylazine.
