The antidepressant-like effect of tipepidine was studied in rats. Tipepidine at 20 and 40 mg/kg i.p. reduced immobility in the forced swimming test and tipepidine at 40 mg/kg, i.p. increased climbing in the test. The drug at 40 mg/kg, i.p. had no effect on the locomotor activity and motor coordination. These results suggest that tipepidine may be a novel drug with antidepressant-like activity.
