Different members of tricyclic antidepressants (TCAs) were found to induce free radical and oxidative stress in vitro. Accordingly, in the present study we tried to explore the possible role of oxidative stress in TCAs-induced cardiotoxicity. Rats were given a single injection of clomipramine (45 mg/kg). ⋯ Addition of hydroxyl radical scavenger or iron chelator significantly counteracted the effect of clomipramine. In conclusion, the present study demonstrates that free radical generation and oxidative stress play a role in clomipramine-induced cardiotoxicity. In addition, clomipramine can induce hydroxyl radical in vitro.
