Flumazenil is the specific antagonist used to reverse the effects of benzodiazepine overdose. It acts by competitively inhibiting the benzodiazepine receptors in the central nervous system. This reverses the sedative effects of benzodiazepines, restoring normal consciousness and respiratory function in cases of overdose. Its use is particularly beneficial in patients with isolated benzodiazepine overdose, as it can quickly mitigate symptoms such as excessive sedation and respiratory depression.

Other options do not serve this purpose effectively. Naloxone is an opioid antagonist used for reversing opioid overdose, not benzodiazepines. Pralidoxime is primarily used to treat organophosphate poisoning and does not reverse benzodiazepine effects. Activated charcoal may be used to reduce the absorption of various substances including benzodiazepines if given shortly after ingestion, but it does not reverse their effects. Thus, flumazenil is the appropriate and effective agent for reversing benzodiazepine overdoses.
