Objective: The present study was designed to investigate the protective and potential effect of gallic acid against doxorubicin (DOX) induced cardiotoxicity. Materials and Methods: Adult Wistar albino rats of either sex weighing 150-200 g were used in this study. DOX administered intraperitoneally in six equal injections (each containing 2.5 mg/kg at 48 h intervals) to total cumulative doses of 15 mg/kg over a period of 2 weeks to induce cardiotoxicity. The estimation of cardiac and lipid biomarkers of both control and treated animals were observed. In vivo antioxidant parameters such as glutathione, superoxide dismutase, catalase, and malondialdehyde were also monitored. The remaining portion of the heart tissue used for histopathological studies. Results: The treatment with doxorubicin increased the levels (P > 0.01) of serum cardiac and lipid biomarker which were brought down by gallic acid treatment. It also exhibited electrocardiographic changes such as reduced R wave and ST segment elevation. Histopathological study revealed that gallic acid restored the myocardial cells towards normal. The restoration of the endogenous antioxidant system clearly depicts that gallic acid have produced its protective effect by scavenging the reactive oxygen species. Conclusion: The results of this study indicated that the cardioprotective effect of gallic acid might be attributed to its antioxidant property.
