Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Deferoxamine chelates iron by forming a stable complex (ferrioxamine) that is excreted renally, preventing iron from catalyzing free radical formation and reducing tissue damage.
Deferasirox is an oral iron chelator that selectively binds iron (Fe3+) with high affinity, forming a stable complex that is excreted primarily in the feces. It reduces iron overload by promoting iron excretion.
For acute iron intoxication: 1 g intramuscularly initially, then 0.5 g every 4 hours for 2 doses, then 0.5 g every 4-12 hours up to a maximum of 6 g/day. For chronic iron overload: 20-40 mg/kg/day subcutaneously over 8-12 hours via infusion pump, or 1-2 g intravenously over 8-24 hours.
Oral: Initial 20 mg/kg/day (max 30 mg/kg/day) administered once daily; titrate based on serum ferritin. For patients >14 years with serum ferritin >1000 mcg/L, use 20 mg/kg/day. Sprinkle capsules can be opened and contents sprinkled on soft food.

Terminal elimination half-life is approximately 5-6 hours for the parent drug after IM or IV administration. The half-life of ferrioxamine is about 6 hours. Clinical context: repeated dosing may be needed for sustained chelation.
8–28 hours (mean 11–19 hours); prolonged half-life correlates with iron overload and may require dose adjustments.
Primarily renal; within 24 hours, approximately 50% of an intramuscular dose is excreted as unchanged drug and 20% as ferrioxamine (the iron chelate). Biliary excretion is minor (<10%).
Primarily fecal (84% of absorbed dose); renal excretion accounts for approximately 8% of total clearance.
