Presently, treatment of anxiety with standard anti-anxiety drugs is associated with a number of shortcomings inviting us to study newer agents that would overcome these problems or search for the drugs or substances, which would enhance the efficacy or reduce the dose or toxicity of this standard anti-anxiety drug diazepam. Ganaxolone (GNX) a positive allosteric modulator of GABA A receptors, may represent a new treatment approach for anxiety. The present study was undertaken to evaluate the

Wistar strain albino rats weighing 200-250 gm were used. Ganaxolone produced significant anti-anxiety effect compared to control group but the activity was less when compared to diazepam. The sedative and muscle relaxant properties of ganaxolone were weak as compared to diazepam. Ganaxolone had significant synergistic effect with diazepam by potentiating its actions, thereby providing a lead for exploring potential benefit of adding ganaxolone to decrease the dose of diazepam in the treatment of anxiety.
