Amisulpride, an atypical antipsychotic was evaluated for antidepressant like activity in forced swimming test in Swiss albino mice. The effect of amisulpride was compared with that of fluoxetine, the standard antidepressant and olanzapine, another atypical antipsychotic claimed to have antidepressant like activity. Both acute and chronic studies were carried out. In both the studies, animals were divided into four groups (n = 8 each) and subjected to oral drug interventions as follows -- Group 1- control (distilled water, 1 mL/kg); Group 2- fluoxetine in a dose of 10 mg/kg 23.5, 5 and 1 h before the test; Group 3-amisulpride in a dose of 70 mg/kg 23.5, 5 and 1 h before the test; Group 4- olanzapine in a dose of 2 mg/kg 23.5, 5 and 1 h before the study. In the chronic study, the treatment was given daily for 28 days with last dose being given 2 h prior to the test. A time sampling method was used to score the behavioral activity in each group. Results of both the studies indicated that animals given amisulpride displayed significant improvement in swimming behavior (p < 0.01), while markedly reducing immobility as compared to control group (p <0.01). Fluoxetine also showed significant difference in activity as compared to amisulpride and olanzapine (p < 0.01). There was no statistically significant difference between amisulpride and olanzapine in terms of effect on immobility and swimming phases in albino mice (p > 0.05). We conclude that amisulpride per se has an antidepressant like activity comparable to that of olanzapine though the activity was significantly less than that of fluoxetine.
