Which alpha-2 agonist is FDA-approved in horses and used as a premed prior to general anesthesia?

• A. Romifidine
• B. Detomidine
• C. Propantheline
• D. Glycopyrrolate

Answer: (A)

Alpha-2 adrenergic agonists provide sedation and analgesia by dampening sympathetic outflow through CNS receptors, making them ideal premeds before anesthesia in many species. In horses, Romifidine is the alpha-2 agonist that is FDA-approved for equine use specifically as a premed. It’s formulated for horses and reliably produces calming effects with some analgesia, helping smooth the path to induction of anesthesia. The other options are anticholinergic drugs that reduce secretions or counter vagal effects but do not act as alpha-2 agonists, so they don’t fulfill the role of the alpha-2 premed in this context.
