Zinecard (DEXRAZOXANE)

Pfizer · FDA-approved approved Small molecule Verified Quality 75/100

Zinecard works by binding to metal ions and preventing them from causing damage to DNA during anthracycline treatment.

Zinecard (Dexrazoxane) is a cytoprotective agent developed by Pharmacia and Upjohn, now owned by Pfizer. It targets DNA topoisomerase 2-alpha to prevent cardiomyopathy and extravasation injury caused by anthracycline injection. Zinecard is approved for the prevention of CMV disease after organ transplant and is available as a generic medication. The drug has a half-life of 2.5 hours and is off-patent, with no active Orange Book patents. Key safety considerations include potential nephrotoxicity and hepatotoxicity.

Mechanism of action

The mechanism by which dexrazoxane reduces tissue damage caused by anthracycline-related cardiomyopathy or following anthracycline extravasation is not fully understood. Dexrazoxane is cyclic derivative of EDTA that penetrates cell membranes. Results of laboratory studies suggest that dexrazoxane is converted intracellularly to ring-opened chelating agent that interferes with iron-mediated free radical generation. Some evidence suggests that dexrazoxane inhibits topoisomerase II reversibly.
