Doxorubicin-induced cardiotoxicity and cardioprotective agents: classic and new players in the game

Abstract

Doxorubicin (DOX) is a cytostatic antibiotic from the class of anthracyclines widely used in chemotherapeutic cancer treatments. Despite the efficiency against several types of cancer, the use of DOX remains limited due to the side effects, especially cardiotoxicity. Among the DOX administration strategies, there are the “classic players” such as nanoparticles and polymers, which are capable of DOX delivery directly to interesting neoplastic regions. On the other hand, the “new players” such as phytochemicals and probiotics emerged with the proposal to react with DOX free radicals, reducing the oxidative stress, inflammatory and apoptotic process. Thus, this review aims to report the studies involving these classics and new players along the years that focus on improved administration and reduction of DOX-induced cardiotoxicity.
