According to the American Addiction Centers, most intentional ingestions of benzodiazepines involve co-ingestion with other substances like alcohol, which increases the risk of serious complications. The primary medication used to reverse benzodiazepine effects and answer the question of what blocks benzodiazepines is flumazenil.

Due to its extremely long and variable half-life—averaging around 58 days—the antiarrhythmic drug amiodarone cannot be immediately reversed. Instead of an antidote, managing amiodarone's effects or toxicity involves discontinuing the medication and implementing supportive care, a process that can take weeks or months to see full effect.

Flumazenil is a powerful antidote that specifically reverses the sedative effects of benzodiazepines. Its rapid onset of action, typically within one to two minutes, makes it a critical tool for medical professionals in various clinical settings. What is the drug flumazenil used for, and why is its competitive antagonism of central nervous system (CNS) benzodiazepine receptors so important for patient care?
