Abstract
INTRODUCTION: Stress can cause harmful effects in the body that induce a wide range of biochemical and behavioural changes. As anti-stress drugs are routinely used to combat stress hence study is needed to assess the contraindication of these drugs in the physiological systems. AIM: To investigate the effect of alprazolam on restrained stress induced alteration of serum cortisol, and antioxidant vitamin levels in male albino rats. MATERIALS AND METHODS: Adult male albino rats (body weight 175-225g) were divided into four groups of six animals in each. Group I (control), kept undisturbed in the metabolic cage throughout the 42 days experimental period. Group II (stress) rats were kept in a wire mesh restrainer for 6 hr/day for 42 days. Group III (stress+ withdrawal) rats were stressed for 21 days and withdrawal of stress for remaining 21 days (total 42 days). Group IV (stress + alprazolam) rats were only stressed for 21 days and treated with drug alprazolam (5mg/kg body weight, intraperitoneal) in continuation with stress for remaining 21 days (total period is 42 days). At the end of 42 days all the rats were sacrificed and serum cortisol, vitamin C and E levels were estimated. RESULTS: Group II (stressed) showed a significant increase in serum cortisol level with concomitant decrease of serum vitamin C and E levels. Group III (withdrawal) and Group IV (+alprazolam) rats showed significant reduction of serum cortisol along with subsequent increase of serum vitamin C and E concentrations. CONCLUSION: Results indicate a possible antioxidant effect of alprazolam on restrained stress induced alteration of serum cortisol and antioxidant vitamin levels.
