ABSTRACT
Background:
Anxiety has become a very important area of research interest in psychopharmacology as it affects one-eighth of the population worldwide. Benzodiazepines are still the most commonly used drugs for anxiety despite a number of side effects.There is a need for newer antianxiety drugs with increased safety and efficacy, hence this study was undertaken to evaluate the anxiolytic activity of Nerium oleander flowers.Methods:
Aqueous extract of Nerium oleander flowers (NA) was prepared using soxhalet apparatus. A total of 24 Albino rats aged 8-10 weeks of either sex weighing about 100-150g were obtained and divided into 4 groups of 6 rats each. Group I Normal saline 10mL/kg. Group II Diazepam 2mg/kg Group III NA at a dose of 200 mg/kg Group IV NA at a dose of 400mg/kg. The anxiolytic activity of Aqueous extract of NA was tested by elevated plus maze and digital actophotometer models. Data was analysed using one way ANOVA followed by Posthoc Tukey’s test.Results:
In EPM model, the NA at 200, 400mg/kg doses showed that the number of entries and time spent in the open arms were increased significantly as compared to the control animals. (p<0.001). In Actophoptometer model, two different doses of NA (200 and 400mg/kg) showed a dose-dependent decrease in the locomotor activity, when compared to the control animals (p<0.001).Conclusions:
Both the doses of aqueous extract of Nerium oleander flowers (200mg and 400mg/kg) possess anxiolytic activity and could be used as a new approach to treat anxiety.
