Dexrazoxane Injection


Dexrazoxane injection (Totect, Zinecard) is used to prevent or decrease thickening of the heart muscles caused by doxorubicin in women who are taking the medication to treat breast cancer that has spread to other parts of the body. Dexrazoxane injection (Totect, Zinecard) is only given to women who have already received a certain amount of doxorubicin and who will need continued doxorubicin treatment, it is not used to prevent heart damage in women who are starting treatment with doxorubicin. Dexrazoxane injection (Totect) is used to decrease damage to the skin and tissues that may be caused when an anthracycline chemotherapy medication such as daunorubicin (Cerubidine), doxorubicin (Adriamycin, Doxil), epirubicin (Ellence) or idarubicin (Idamycin) leaks out of a vein as it is being injected. Dexrazoxane injection is in classes of medications called cardioprotectants and chemoprotectants. It works by stopping the chemotherapy medications from damaging the heart and the tissues.
