Abstract BACKGROUND/AIM: Antidepressants are frequently prescribed concurrently with anti-cancer drugs and may have synergistic, additive or antagonistic effects. The present work investigated the effect of antidepressants on the cytotoxicity of platinum agents cisplatin, carboplatin and oxaliplatin. MATERIALS AND METHODS: The cytotoxicity of platinum drugs alone or in combination with antidepressants was measured in HCT116 wild-type (wt), HCT116 (p53 -/-), HT-29, SKOV3 and A2780 cells using an apoptosis-based assay. RESULTS: The effect of antidepressants on platinum cytotoxicity is both cell type- and drug dependent. Mostly additive effects were observed. Desipramine and fluoxetine caused the greatest effects, with cisplatin in general being most sensitive to their presence. There is little effect of p53 status on the drug-drug interaction while the calmodulin inhibitor W7 augmented cisplatin cytotoxicity relative to carboplatin and oxaliplatin. CONCLUSION: The drug-drug interaction between antidepressants and platinum anti-cancer agents requires detailed evaluation for optimization of patient care.
