Deferiprone (Ferriprox) is an iron-chelating agent in oral tablet form whose efficacy has been shown to be equivalent to that of deferoxamine [12-16]. The objective of iron chelation is to avoid the complications of iron overload such as cardiac and hepatic dysfunction. Chelation therapy significantly improves myocardial T2* (a magnetic resonance technique for assessing tissue iron concentration) and left ventricular function. [ 33, 34] Administered intramuscularly (IM). Overview; Fingerprint; Abstract. Most of the storage iron in the body is in hepatocytes, and the ferritin in these cells is turned over less frequently (every few days).
