Harmane Induces Anxiolysis and Antidepressant‐Like Effects in Rats

Abstract

A forced swim test (FST) and an elevated plus maze (EPM) were used to determine antidepressant and anxiolytic effects of harmane in rats in comparison with a known antidepressant, imipramine (30 mg/kg i.p.). Harmane (2.5, 5.0, or 10 mg/kg, i.p.), saline, or imipramine were given 30 minutes before the tests. Administration of harmane decreased the time of immobility in the FST dose‐dependently and increased the time spent in open arms in the EPM, as compared with the saline group. As an endogenous substance, harmane therefore has anti‐anxiety and antidepressant effects.
