To evaluate antidepressant like effect of tramadol in mice.
Tramadol was administered at three different doses (10,20 and 40 mg/kg, i.p) once daily for 7 days to Swiss albino mice of either sex. The immobility period of control and drug treated mice were recorded in tail suspension test (TST).The antidepressant effect of tramadol was compared to that of fluoxetine (20 mg/kg, i.p), administered for seven days.
Tramadol produced significant antidepressant effect at all the doses, as indicated by reduction in immobility times as compared to control. The efficacy of tramadol at doses of 20 and 40 mg/kg was comparable with that of fluoxetine. Tramadol at 10 mg/kg dose showed significantly less antidepressant activity compared to fluoxetine.
The results of the present study indicate antidepressant like activity of tramadol.
评估曲马多在小鼠体内的抗抑郁样作用。
将曲马多以三种不同剂量（10、20 和 40 mg/kg，ip）每天一次连续给药 7 天，用于雄性和雌性瑞士白化小鼠。在悬尾试验（TST）中记录对照组和药物处理组小鼠的不动期。将曲马多的抗抑郁作用与氟西汀（20 mg/kg，ip）进行比较，氟西汀给药 7 天。
与对照组相比，曲马多在所有剂量下均产生显著的抗抑郁作用，表现为不动时间减少。曲马多在 20 和 40 mg/kg 剂量下的疗效与氟西汀相当。曲马多在 10 mg/kg 剂量下的抗抑郁活性明显低于氟西汀。
本研究结果表明曲马多具有抗抑郁样活性。
