描述 | Flumazenil, an imidazobenzodiazepine derivative, is an antagonist of the GABA/benzodiazepines receptor complex that might play a role in the treatment of hepatic encephalopathy[3]. Flumazenil can antagonize the hypnotic and sedative effects of benzodiazepines at gamma-amino butyric acid receptors. Flumazenil could be considered in cases in which quick recovery is required and should be administered intravenously in small, incremental doses[4]. Intravenous antagonist doses of 0.2 mg followed by 0.1 mg/min to a total dose of 1 mg have produced significant results in reversing benzodiazepine sedation. As much as 5 mg of flumazenil have been necessary when treating benzodiazepine or mixed-agent intoxications. Flumazenil is well tolerated locally as well as systemically[5]. Because flumazenil appears to be specific in its antagonism of benzodiazepine-induced respiratory and CNS depression, it could be used empirically to confirm or exclude a role of benzodiazepines in the generation of mental status changes in the setting of overdose or coma of unknown origin[6]. |
