Dexrazoxane (dexrazoxane) — Uses, Dosage, Side Effects & Safety

Drug class: Cardioprotective agent; Antidote (extravasation)

Overview

Dexrazoxane is a medication used to help protect the heart from damage caused by certain chemotherapy drugs, especially anthracyclines like doxorubicin and daunorubicin. It is also used to treat accidental leakage (extravasation) of anthracycline chemotherapy into the tissues around the injection site, which can cause severe tissue damage. Dexrazoxane works by reducing the harmful effects of free radicals and iron-mediated damage in heart tissue. This helps lower the risk of heart problems, such as heart failure, in patients receiving high doses of chemotherapy. It is given by intravenous infusion and is usually administered just before chemotherapy. Patients should know that dexrazoxane is not a cancer treatment itself, but a supportive medication to minimize side effects of cancer therapy. It may cause side effects, and regular monitoring is needed during treatment.
