Cardioxane is a medication primarily used as a protective agent in cancer treatment, specifically designed to safeguard the heart against the potential toxic effects of certain chemotherapy drugs. Its active ingredient, dexrazoxane, works by chelating iron, a mechanism thought to reduce the formation of free radicals and thereby mitigate damage to heart tissue. Cardioxane is often administered to patients receiving anthracycline chemotherapy, a class of drugs known for their efficacy in treating a wide range of cancers but also associated with a risk of cardiotoxicity. By minimizing heart damage, Cardioxane helps ensure that patients can complete their prescribed chemotherapy regimens with a reduced risk of developing heart-related complications.
