Abstract

Cyclophosphamide (CP), one of the most widely prescribed antineoplastic drugs could cause a lethal cardiotoxicity. The present study is aimed at evaluating the role of dl-α-lipoic acid (LA) in oxidative cardiac damage induced by CP. Adult male Wistar rats were divided into four treatment groups. Two groups received single intraperitoneal injection of CP (200 mg/kg BW) to induce cardiotoxicity, one of these groups received LA treatment (25 mg/kg BW for 10 days). A vehicle treated control group and a LA drug control were also included. Cardiotoxicity, evident from increased activities of serum creatine phosphokinase, lactate dehydrogenase, aspartate transaminase and alanine transaminase in CP administered rats, was reversed by LA treatment. CP administered rats showed abnormal levels of enzymic (superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase and glutathione-S- transferase) and non-enzymic antioxidants (glutathione, vitamin C and vitamin E) along with high malondialdehyde levels. However, normalized lipid peroxidation and antioxidant defenses were reported in the LA treated rats. These findings highlight the efficacy of LA as a cytoprotectant in CP induced cardiotoxicity.
