BACKGROUND: Doxorubicin is a widely used agent in the treatment of cancer, but the cardiotoxicity associated with this drug limits its potential for use. The cardioprotective effects of dapagliflozin, an antidiabetic drug, have the potential to counteract the cardiotoxic effect of doxorubicin therapy. In our study, we aimed to investigate the protective effect of dapagliflozin from possible doxorubicin-induced cardiotoxicity. METHODS: A total of 40 male Wistar albino rats were divided into 4 groups consisting of 10 each (control = 10, dapagliflozin = 10, doxorubicin = 10, doxorubicin + dapagliflozin = 10). Meanwhile, doxorubicin and doxorubicin + dapagliflozin groups received a total dose of 15 mg/kg doxorubicin intraperitoneally, dapagliflozin and doxorubicin + dapagliflozin groups were gavaged daily with 10 mg/kg dapagliflozin. At the sixth week of the study, rats were examined by echocardiography and electrocardiogram. Furthermore, histopathological method was used to evaluate the level of cardiotoxicity. RESULTS: Ejection fraction decreased by 15% in the doxorubicin group, and this reduction in ejection fraction was alleviated in the doxorubicin + dapagliflozin group. In addition, a 65% increase in QRS duration was observed in the group given doxorubicin, while an increase of 7% was observed in doxorubicin + dapagliflozin group. Corrected QT duration increased by 12% in the doxorubicin group, compared to 2% in doxorubicin + dapagliflozin group. Meanwhile, sarco-myolysis, inflammatory cell infiltration, and necrotic changes were examined heavily in doxorubicin group, they were minimal in doxorubicin + dapagliflozin group. CONCLUSION: Our study showed that dapagliflozin has the potential to reduce the effects of doxorubicin-induced cardiotoxicity. |
