For reducing the incidence and severity of cardiomyopathy associated with doxorubicin administration in women with metastatic breast cancer who have received a cumulative doxorubicin hydrochloride dose of 300 mg/m^2 and would benefit from continued doxorubicin therapy. Also approved for the treatment of extravasation from intravenous anthracyclines.
The mechanism by which dexrazoxane exerts its cardioprotective activity is not fully understood. Dexrazoxane is a cyclic derivative of EDTA that readily penetrates cell membranes. Results of laboratory studies suggest that dexrazoxane (a prodrug) is converted intracellularly to a ring-opened bidentate chelating agent that chelates to free iron and interferes with iron-mediated free radical generation thought to be responsible, in part, for anthracycline-induced cardiomyopathy. It should be noted that dexrazoxane may also be protective through its inhibitory effect on topoisomerase II.
Intraperitoneal, mouse LD<sub>10</sub> = 500 mg/kg. Intravenous, dog LD<sub>10</sub> = 2 gm/kg.
IV administration results in complete bioavailability.

Urinary excretion plays an important role in the elimination of dexrazoxane. Forty-two percent of the 500 mg/m2 dose of dexrazoxane was excreted in the urine.
