Comparison of pharmacokinetics and urinary iron excretion of two single doses of deferiprone in β-thalassemia/hemoglobin E patients.

Dose-related pharmacokinetics and urinary iron excretion (UIE) of an orally active iron chelator, deferiprone (L1), was investigated in 12 severe β-thalassemia/hemoglobin E patients. The patients received two single doses of 25 and 50 mg/kg with a 2-week washout period. Deferiprone was rapidly absorbed and reached maximum concentration (C(max)) within 1 h after administration.
