Oral iron chelation with deferiprone

O Diav-Citrin1, G Koren

  • 1Department of Pediatrics, Hospital for Sick Children, Toronto, Ontario, Canada.

Pediatric Clinics of North America

Summary

Deferiprone is an effective oral iron chelator for chronic iron overload, but its use is limited by adverse effects like agranulocytosis. Further research is needed to understand and prevent these side effects.

Reproductive toxicology (Elmsford, N.Y.)·1998

Area of Science:

  • Pharmacology
  • Hematology
  • Clinical Medicine

Background:

  • Deferiprone is the most extensively researched oral iron chelator.
  • It is the only oral iron chelator proven effective for long-term negative iron balance in chronic iron overload.
  • Current use is restricted due to adverse effects like agranulocytosis and arthropathy.

Purpose of the Study:

  • To review the effectiveness and safety of deferiprone in managing chronic iron overload.
  • To highlight ongoing clinical trials investigating deferiprone's long-term efficacy and adverse event profile.
  • To explore the potential of combined iron chelation therapy and identify new therapeutic indications.

Main Methods:

  • Review of existing clinical trial data on deferiprone.
  • Analysis of reported adverse effects, including agranulocytosis and arthropathy.
  • Examination of ongoing research into deferiprone's mechanisms and potential new uses.

Main Results:

  • Deferiprone demonstrates effectiveness in achieving negative iron balance.
  • Serious adverse effects necessitate careful monitoring and limit widespread use.
  • Deferiprone remains a viable option when desferrioxamine is contraindicated or unavailable.

Conclusions:

  • Deferiprone is an important therapeutic option for chronic iron overload, particularly when other treatments are not feasible.
  • Further research is crucial to elucidate mechanisms of adverse effects and develop predictive/preventive strategies.
  • Continued exploration of iron-chelating therapies holds promise for new clinical applications.
