Interaction of Flomazenil with Anxiolytic Effects of <i>Citrus aurantium</i> L. Essential Oil on Male Mice

Abstract

Due to our previous findings about the role of GABAegic neurotransmission in anxiolytic effects of Citrus aurantium L. essential oil, we are now presenting flomazenil interaction with this herb, as an antagonist of benzodiazepines at GABA receptor. The study was performed on 84 male albino mice assigned to 14 groups of six. The animals were injected intraperitoneally with the Citrus aurantium L. essential oil for 5 days. On the fifth day, either normal saline or flomazenil (0.1 mg/kg) was injected to the experimental groups. Thirty minutes after the injection, all the groups were assessed for anxiety-related behavior by elevated plus-maze test. In groups receiving Citrus aurantium L. essential oil at doses of 2.
