Xylazine produces sedation primarily through stimulation of which receptor type?
Correct answer: B. Alpha-2 adrenergic receptors
- A. Alpha-1 adrenergic receptors
- B. Alpha-2 adrenergic receptors
- C. Beta-1 adrenergic receptors
- D. Muscarinic receptors
Explanation
Xylazine is an alpha-2 adrenergic agonist that reduces norepinephrine release and produces sedation, analgesia and muscle relaxation. Its alpha-2 effects can also cause bradycardia and reduced cardiac output.
