To prevent side effects of excessive accumulation of iron in the body, chelation therapy is recommended in transfusion-dependent patients. The reaction between deferiprone and iron to form a complex red substance can be described as 3 molecules of the chelator, deferiprone, reacting with a molecule of iron. However, the actual mechanism of the deferiprone-iron binding reaction is not well under...

Deferiprone is an orally active iron chelator which has emerged from an extensive search for new treatment of iron overload. Comparative studies have shown that at comparable doses deferiprone may be as effective as deferoxamine in removing body iron. Retrospective and prospective studies have shown that deferiprone monotherapy is significantly more effective than deferoxamine in improving myoc...

Deferiprone (1, 2 dimethyl-3-hydroxypyrid-4-one) is considered to be the standard iron chelator. Pharmacokinetic studies of generic formulations are required in local condition before placed on the market. High performance liquid chromatographic (HPLC) method was used for quantification of deferiprone in human plasma using UV/VIS detector. Chromatographic separation was carried out on C(18) col...

Deferiprone Superficial siderosis (SS) is a neurodegenerative condition caused by hemosiderin deposition on the surface of the brain, cranial nerves, and spinal cord. SS is an exceptionally rare condition characterized by a triad of hearing loss, ataxia, and myelopathy. The most common etiologies that lead to SS are trauma, previous surgical procedures, dural tears, and tumors of the central ne...

Approximately 6% of patients with thalassemia receiving deferiprone develop neutropenia. Present practice is to monitor absolute neutrophil count (ANC) weekly and to interrupt treatment at the first sign of neutropenia, lest continuation lead to progressive neutrophil reduction. In a 6-month study evaluating the safety and efficacy of a liquid form of deferiprone in 100 children, ANC was initia...

Tissue iron overload constitutes a major health problem for people who require regular blood transfusions, such as those with beta-thalassemia major. Deferiprone is a hydroxypyridinone iron chelator used therapeutically to remove this excess iron and prevent tissue damage. Deferiprone is metabolized by UDP-glucuronosyltransferases (UGTs) into deferiprone 3-O-glucuronide (DG), but a systematic e...

Kojic acid and deferiprone are iron chelators used for skin lightening and iron-overload treatment, respectively. As iron chelation and free radical scavenging are principal factors for wound healing, it was hypothesised that the local application of these compounds might accelerate wound healing in rats. Ointments of 3%, 6% and 9% of deferiprone and kojic acid were prepared and topical treatme...

Deferoxamine (DFO) therapy has been associated with improved survival of thalassemia patients. However, cardiac disease remains the main cause of death in those patients. In 1995, the oral chelator deferiprone became available for clinical use. We compared the occurrence of cardiac disease in patients treated only with DFO and in those whose therapy was switched to deferiprone during the period...

BACKGROUND AND PURPOSE Superficial siderosis is a neurodegenerative disease caused by toxic accumulation of hemosiderin on the surface of the brain and spinal cord for which there is no known effective treatment. METHODS Oral deferiprone, a lipid-soluble iron chelator with ability to cross the blood-brain barrier, at a dose of 30 mg/kg per day was tested for safety in an open pilot study in 1...

Anthracycline cardiotoxicity ranks among the most severe complications of cancer chemotherapy. Although its pathogenesis is only incompletely understood, "reactive oxygen species (ROS) and iron" hypothesis has gained the widest acceptance. Besides dexrazoxane, novel oral iron chelator deferiprone has been recently reported to afford significant cardioprotection in both in vitro and ex vivo cond...
