Deferiprone is indicated for the treatment of iron overload patients with thalassemia major when deferoxamine therapy is contraindicated or inadequate. Deferiprone therapy should be initiated and maintained by a physician experienced in the treatment of patients with thalassemia.
Deferiprone is a chelating agent with an affinity for ferric ion (iron III). Deferiprone binds with ferric ions to form neutral 3:1 (deferiprone:iron) complexes that are stable over a wide range of pH values. Deferiprone has a lower binding affinity for other metals such as copper, aluminum and zinc than for iron.
