BACKGROUND Mirtazapine, a noradrenergic and specific serotonergic antidepressant, which blocks the α2-adrenergic autoreceptors and heteroreceptors, has shown anxiolytic properties in clinical trials and preclinical animal experiments. The addition of mirtazapine to selective serotonin reuptake inhibitors (SSRIs) is clinically suggested to be more effective for anxiety disorders. In this study, ...

Glinus oppositifolius is a small herb, widely used in the traditional medicine of Bangladesh in treatment of a variety of diseases and disorders such as insomnia, pain, inflammation, jaundice, and fever. The present study evaluated the sedative and anxiolytic potentials of the ethanol extract of leaves of G. oppositifolius (EEGO) in different behavioral models in mice. The sedative activity of ...

Several variables, including age, are known to influence anxiety. Previous exposure to the elevated-plus maze (EPM) is known to modify emotional behaviour as retesting in the EPM at a standard age of 3 months increases open-arm avoidance and attenuates the effects of anxiolytic drugs. This study analysed whether similar results are obtained when older animals are subjected to these experimental...

Prior test experience compromises the anxiolytic efficacy of benzodiazepines (BZs) either in rats or mice, a phenomenon not exclusive to the elevated plus-maze (EPM) animal model of anxiety, which is referred to as "one-trial tolerance." However, it remains to be determined whether a similar event occurs when testing other drugs that also possess binding-sites on the GABA(A) receptor, such as e...

Putative activity of hydroalcoholic and aqueous infusion extracts of Echium amoenum L. was investigated in mice using the rotarod model of motor coordination and the elevated plus maze model of anxiety. The extracts were administered intraperitonealy (i.p.) once, one hour before performing the tests. Preliminary phytochemical study of the plant, with standard procedures, showed that it contains...

conclusions acute and chronic administration of ellagic acid had anxiolytic property. also, the most effective dose of ellagic acid was 30 mg/kg. pretreatment with flumazenil reversed the beneficial effect of ellagic acid and diazepam on anxiety. it is likely that the anxiolytic effect of ellagic acid is largely mediated by activation of gabaa receptor. results acute and chronic application of ...

Tamarindus indica (Fabaceae) have been using in traditional medicine to cure various diseases, including mental stress and anxiousness. The current study was aimed evaluate phytochemical analysis anxiolytic activity of flower extracts (n-Hexane, Ethyl acetate, Chloroform methanol) different animal models such as elevated plus-maze, mirror chamber, light/dark, hole board tests. had showed presen...
