Abstract

ABSTRACT


Introduction: Anxiety is a psychological and physiological state characterized by somatic, emotional, cognitive, and behavioural components with displeasing feeling of fear and concern. Among all the antianxiety drugs benzodiazepines are commonly employed drugs for the treatment but they do have limitations. Considering the high prevalence of anxiety disorders and lack of an ideal anxiolytic drug, search for better anxiolytic drugs continue. Hence this study was undertaken to evaluate the acute and chronic anxiolytic effects of Nifedipine in comparison to Diazepam using in Swiss Albino mice using two behavioural models


Methods: 30 Swiss Albino mice were divided into 5 groups with 6 mice in each group. The study was conducted in two phases to evaluate the acute & chronic effects. The groups consisted of Diazepam(1mg/kg), 3 doses of Nifedipine (2.6mg/kg, 5.2mg/kg & 10.4mg/kg) & vehicle control. The elevated plus maze and light & dark box was used to evaluate the anti-anxiety effects. The number of entries and time spent in open arm of Elevated Plus maze and in light area of Light and dark box model were noted and compared among the 5 groups. Observations were analysed using ANOVA and Post hoc Tukey’s test.


Results: Medium & high doses of Nifedipine significantly increased the number of entries and time spent in open arm and light area in both models (p<0.05).


Conclusion: Two doses of Nifedipine possess anti-anxiety effects both on acute and chronic administration in both Elevated Plus maze & Light and dark box model.
