Are there reversals for induction agents such as ketamine, telazole, alfaxalone, and propofol?

• A. Yes
• B. No
• C. Sometimes
• D. Only for propofol

Answer: (B)

The idea is that reversal of induction drugs isn’t universal; some components can be reversed, but not the entire drug effect.

Ketamine has no dedicated antidote—there’s no reliable reversal agent, so emergence relies on metabolism and ventilation support.

Telazol is a combination of tiletamine and zolazepam. While there’s no antidote for tiletamine, the benzodiazepine zolazepam can be reversed with flumazenil. That means you can partially reverse the sedative component, but you won’t reverse the entire induction because tiletamine’s effects remain. So, you get partial, not complete, reversal.

Alfaxalone and propofol do not have specific reversal agents; management is supportive, focusing on ventilation and continued monitoring as the drug wears off.

Therefore, reversal is possible in a limited sense for a combination product like Telazol, but not for the other induction agents listed. The best overall answer reflects that nuance: sometimes.
