Objectives: Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed antidepressant drugs. The addition of low dose of 5-hydroxytryptamine type 2A enhances the therapeutic effect of SSRIs. The purpose of the present studies was to test the effects of combined treatment of a low dose of ketanserin (KET) and escitalopram (ESC) on behavioral anomalies occurring after olfactory bulbectomy (OBX).
Materials and Methods: Chronic Depression was induced by OBX as shown in behavioral tests such as Open field, social interaction, and hyperemotionality tests. Acute and chronic treatment effect of KET, ESC, and combination was administered to the OBX rats.
Results: Chronic (14 days) treatment with KET (1 mg/kg) or ESC (10 mg/kg) alleviated the behavioral anomalies of olfactory bulbectomized rats in modified open field exploration, social interaction, hyperemotionality. When KET treatment was combined with ESC, a short duration regimen (7 days) was sufficient to reverse the bulbectomy-induced anomalies.
Conclusion: The combination therapy as a likely strategy to achieve an early-onset of antidepressant action.
