After hydrolysis to an active form that is similar to ethylenediaminetetraacetic acid (EDTA), dexrazoxane chelates iron, limiting the formation of free radical-generating anthracycline-iron complexes, which may minimize anthracycline-iron complex-mediated oxidative damage to cardiac and soft tissues.  This agent also inhibits the catalytic activity of topoisomerase II, which may result in tumor cell growth inhibition."}]
