The 5HT4 receptor agonists are antidepressants with a unique mode of action. Many studies have been done on investigational drugs, and mosapride has been shown to have a 5HT3 antagonistic property. In this study, we assessed the potential anxiolytic and antidepressant effects of mosapride on Wistar albino rats. The rats were randomly assigned to two models containing 4 groups of 6 animals each. In the anxiety model, four groups included 0.5 mL of 0.5% carboxymethyl cellulose (CMC), mosapride 1.5 mg/kg, mosapride 3 mg/kg and diazepam 2 mg/kg. They were dosed for 5 days. On the 3rd day, the elevated plus maze (EPM) was conducted, and on the 5th day, the open field (OF) tests were conducted. In the depression model, four groups included 0.5 mL of 0.5% CMC, mosapride 1.5 mg/kg, mosapride 3 mg/kg and imipramine 30 mg/kg. After 3 days of dosing, the forced swim test (FST) was conducted, followed by a washout period of 1 month. Then, the rats were subjected to chronic unpredictable stress with sucrose preference. Compared with the control, the mosapride-treated animals showed significant anxiolytic behavior at both high and low doses in the EPM and OF tests. In the FST, both high and low doses of mosapride reduced immobility. The climbing behavior was prominent at a high dose of mosapride, whereas swimming was prominent at a low dose. In the chronic stress model, both doses of mosapride preserved sucrose preference comparable to imipramine. These findings suggest that mosapride has anxiolytic and antidepressant activities at clinically used doses.
