The Protective Effect of Cilostazol in Genotoxicity Induced by Methotrexate in Human Cultured Lymphocytes

Background: Methotrexate is an antagonist of folic acid that has been shown to be genotoxic to healthy body cells via induction of oxidative stress. Cilostazol is a phosphodiesterase III inhibitor and a potent antioxidant drug. Objectives: To evaluate the potential protective effect of cilostazol on methotrexate genotoxicity. Results: Methotrexate significantly increased the frequency of CAs and SCEs (p < 0.0001) as compared to control...
