Which statements describe key considerations of alfaxalone?

• A. No analgesia, no reversal, potential for muscle tremors, +/- apnea
• B. Analgesia with a reversal agent, no tremors
• C. Provides sustained analgesia and requires reversal
• D. Requires sedation without analgesia or reversal

Answer: (A)

Alfaxalone is an IV anesthetic used in veterinary patients, but it does not provide analgesia. Because there is no specific reversal agent for it, dosing must be carefully titrated and monitored rather than corrected with an antagonist. Respiratory depression is a known risk with this drug, and apnea can occur, especially if given as a rapid IV bolus. Emergence may be accompanied by muscle tremors or shivering as the patient wakes up. So the statement that best describes its key considerations is that it offers no analgesia, has no reversal, can cause muscle tremors, and may cause apnea.

These points distinguish it from options that imply analgesia or a reversal agent or that downplay tremors or apnea.
