This review summarizes recent progress in therapeutic drugs for doxorubicin-induced cardiomyopathy to provide reference for future clinical treatment.
Doxorubicin (DOX), as a kind of chemotherapy agent with remarkable therapeutic effect, can be used to treat diverse malignant tumors clinically. Dose-dependent cardiotoxicity is the most serious adverse reaction after DOX treatment, which eventually leads to cardiomyopathy and greatly limits the clinical application of DOX. DOX-induced cardiomyopathy is not a result of a single mechanistic action, and multiple mechanisms have been discovered and demonstrated experimentally, such as oxidative stress, inflammation, mitochondrial damage, calcium homeostasis disorder, ferroptosis, autophagy and apoptosis. Dexrazoxane (DEX) is the only protective agent approved by FDA for the treatment of DOX cardiomyopathy, but its clinical treatment still has some limitations. Therefore, we need to find other effective therapeutic drugs as soon as possible. In this paper, the drugs that effectively improve cardiomyopathy in recent years are mainly described from the aspects of natural drugs, endogenous substances, new dosage forms, herbal medicines, chemical modification and marketed drugs. The aim of the present study is to evaluate the effects of these drugs on DOX-induced anticancer and cardiomyopathy curative effects, so as to provide some reference value for clinical treatment of DOX-induced cardiomyopathy in the future.
