Abemaciclib (ABE) is a cyclin-dependent kinase inhibitor used in combination with an antiestrogen in the treatment of breast cancer. In addition to the important therapeutic properties of this drug, its side effects are not fully known. In this study, we aimed to investigate the protective effect of curcumin (CUR) on cardiac damage caused by ABE administration. Forty rats were equally divided into control, dimethyl sulfoxide (150 mu L), CUR (30 mg/kg/day), ABE (26 mg/kg/day), and ABE + CUR (26 mg/kg/day ABE and 30mg/kg/day CUR) groups (n = 8). Injections were administered daily for 28 days. Troponin-I, total cholesterol, and creatine kinase myocardial band (CK-MB) levels and cardiac fibrosis were higher in the ABE group than in the control group (p < 0.05), and were lower in the ABE + CUR group than in the ABE group (p < 0.05). The results showed that ABE administration can cause cardiac damage and increase cardiac fibrosis. However, they showed that coadministration of CUR with ABE could suppress increases in CK-MB, troponin-I, and total cholesterol levels and also cardiac fibrosis associated with cardiac damage. Therefore, we can infer that the subsequent administration of CUR ABE treatment can be used as a therapeutic strategy for preventing cardiac damage.
