Dexrazoxane hydrochloride (Zinecard, Cardioxane) is a cardioprotective agent. It was discovered by Kurt Hellmann in 1972. The IV administration of dexrazoxane is in acidic condition with HCl adjusting the pH.[1]

Uses

Dexrazoxane has been used to protect the heart against the cardiotoxic side effects of chemotherapeutic drugs such as anthracyclines,[2] such as daunorubicin or doxorubicin or other chemotherapeutic agents.[3] However, in July 2011 the US Food and Drug Administration released a statement restricting use only in adult patients with cancer who have received > 300 mg/m2 doxorubicin (an anthracycline) or > 540 mg/m2 epirubicin (another chemotherapeutic agent) and general approval for use for cardioprotection.[4][5] That showed a possibly higher rate of secondary malignancies and acute myelogenous leukemia in pediatric patients treated for different cancers with both dexrazoxane and other chemotherapeutic agents that are associated with secondary malignancies.[6]

The United States Food and Drug Administration has also approved a dexrazoxane hydrochloride drug, brand names Totect and Savene (approved in the EU) marketed by Clinigen Group, for use as a treatment of extravasation resulting from IV anthracycline chemotherapy.[7][8] Extravasation is an adverse event in which chemotherapies containing anthracylines leak out of the blood vessel and necrotize the surrounding tissue.

Mechanism

As a derivative of EDTA, dexrazoxane chelates iron and thus reduces the number of metal ions complexed with anthracycline and, consequently, decrease the formation of superoxide radicals.[9] The exact chelation mechanism is unknown, but it has been postulated that dexrazoxane can be converted into ring-opened form intracellularly and interfere with iron-mediated free radical generation that is in part thought to be responsible for anthryacycline induced cardiomyopathy.[10] It was speculated that dexrazoxane could be used for further investigation to synthesize new antimalarial drugs.[11]
