OBJECTIVE: Doxorubicin (DOX) is a chemotherapeutic agent widely used to treat cancers, particularly breast cancer. DOX has side effects, including cardiotoxicity, hepatotoxicity, and nephrotoxicity. Imipramine is an antidepressant that increases the release of neurotransmitters. This study aimed to investigate the effect of co-administration of imipramine and DOX on DOX-induced toxicity.

MATERIALS AND METHODS: Forty female mice (10-12-weeks-old, 30-38 g) were divided into four groups (n = 10 per group). The animals in the control group received a single-dose saline injection. The animals in the DOX group received a single dose of DOX (20 mg/kg) by intraperitoneal (i.p.) injection. The animals in the imipramine group received the drug daily in their drinking water (0.13 mg/mL) for 9 days, starting 1 day before the DOX injection received by the DOX group. The animals in the combination group (DOX+imipramine) received a single dose of DOX (20 mg/kg, i.p. injection), and a daily dose of imipramine in their drinking water (0.13 mg/mL) for 9 days starting 1 day before the DOX injection. The animals were observed daily to record mortality, and their body weights were recorded every alternate day.

RESULTS: DOX treatment increased the rate of mortality compared with that for control animals. Imipramine co-administration with DOX increased the rate of mortality significantly (p < 0.05) compared with DOX treatment alone. The mortality rate in both the control and imipramine-treatment groups was zero. DOX co-administered with imipramine resulted in significantly reduced body weight compared with control animals.

CONCLUSIONS: The combination of DOX and imipramine reduced the survival rate of female mice, suggesting that imipramine increases the toxic effects of DOX.
