Deferasirox (Exjade) is an oral, once-daily iron chelator widely approved for the treatment of transfusional chronic iron overload. In the EU, deferasirox is indicated in patients with beta-thalassaemia major aged > or =6 years and, in the US, in all transfusional chronic iron overload patients aged > or =2 years. Deferasirox is highly selective for iron as Fe3+. In approximately 1-year clinical trials of patients with transfusional chronic iron overload associated with beta-thalassaemia, sickle cell disease, myelodysplastic syndrome or other rare chronic anaemias, deferasirox 20 or 30 mg/kg/day had a beneficial effect on liver iron concentrations (LIC) and serum ferritin levels; tolerability issues were clinically manageable with regular patient monitoring. Although longer-term efficacy and tolerability data are required, in particular examining the prevention of iron overload-related complications and the effect of deferasirox on renal function, deferasirox is an easily administered iron chelator and is a valuable option in the management of transfusional chronic iron overload.
