Flumazenil

Flumazenil is a benzodiazepine antagonist that binds to GABA_A receptors containing α1, α2, α3, or α5 subunits. It is clinically used to reverse benzodiazepine-induced sedation and toxicity. In neurodegenerative disease research, Flumazenil is studied for its effects on GABAergic signaling, withdrawal syndromes, and its potential to modulate cognitive and behavioral outcomes in CNS disorders.
