Flumazenil is a competitive GABAA receptor antagonist, used in the treatment of benzodiazepine overdoses.
Flumazenil interacts at the central benzodiazepine receptor to antagonize or reverse the behavioral, neurologic, and electrophysiologic effects of benzodiazepine agonists and inverse agonists. Flumazenil is of some benefit in hepatic encephalopathy, but until well-designed clinical trials are conducted, hepatic encephalopathy must be considered an investigational indication for flumazenil. Flumazenil has been shown to reverse sedation caused by intoxication with benzodiazepines alone or benzodiazepines in combination with other agents, but it should not be used when cyclic antidepressant intoxication is suspected[1]. Flumazenil (1 mg/kg) induces a strong anxiolytic effect in BALB/c mice tested in the elevated plus maze and light/dark test[2]. Flumazenil (10 mg/kg) effectively prevents the reduction produced by allopregnanolone in rats[3]. Flumazenil (5-20 mg/kg) antagonizes the anticonvulsant and adverse effects of diazepam but not GYKI 52466 in mice. Flumazenil slightly reduces the anticonvulsant activity of NBQX in the MES model but not in the PTZ test[4]. Flumazenil (3.0 mg/kg) blocks the changes withdrawal from chronic ethanol treatment, which leads to a decrease in open arm time and percent open arm entries[5].

Animal experiment: |
Flumazenil is administered intraperitoneally in a volume of 10 mL/kg body weight 20 min before experimental testing. Two polyvinylchloride boxes (20×20×14 cm) covered with Plexiglas are connected by an opaque plastic tunnel (5×7×10 cm). One of these boxes is darkened. A light from a 100-W desk lamp 40 cm above the other box provided the only room illumination. This light level (300 lux) is chosen in order to avoid strain differences to be detected on time in the lit box (a measure of anxiety behaviour) in control animals. Indeed, in previous experiments, the BALB/c mice differ from C57BL/6 only in the high light condition. The subjects are individually tested in 5-min sessions between 1400 and 1700 hours. Mice are placed in the lit box to start the test session. The time spent in the lit box and the number of transitions from the dark box to the lit one are recorded after the first entry in the tunnel. |
