In benzodiazepine overdose presenting with bradycardia, which antagonist is used?

Flumazenil is the antagonist used for benzodiazepine overdose. It works by competitively blocking the benzodiazepine binding site on the GABA-A receptor, which reverses the central nervous system and respiratory depression caused by benzodiazepines. In a case where bradycardia arises from opioid or CNS depressant effects of a benzo overdose, reversing the sedative influence with flumazenil can improve breathing and circulation by restoring normal autonomic function. It’s specific to benzodiazepines, unlike naloxone (for opioids) or ketamine (a dissociative anesthetic). Diazepam is itself a benzodiazepine, not an antagonist. Be aware that flumazenil can precipitate withdrawal or seizures in chronic benzodiazepine users or in mixed overdoses, so it should be used with caution and under appropriate monitoring.
