IRON DEXTRAN vs PROFERDEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iron dextran is a colloidal solution of ferric oxyhydroxide complexed with dextran, which provides a source of iron for hemoglobin synthesis. After intramuscular or intravenous administration, the iron-dextran complex is taken up by the reticuloendothelial system, where iron is released and bound to transferrin for erythropoiesis.
PROFERDEX (iron dextran) is a colloidal solution of ferric hydroxide in complex with dextran, providing a source of iron for hemoglobin synthesis and erythropoiesis. Iron is incorporated into heme, which is essential for oxygen transport in red blood cells.
IM or IV: Calculate total iron deficit using formula: Body weight (kg) × (target Hb - actual Hb) × 0.24 + 500 mg (for iron stores). Administer as single IV infusion or daily IM doses up to 2 mL (100 mg) per day. IV infusion: Dilute in 0.9% NaCl and infuse over 1-6 hours; test dose of 25 mg recommended.
100 mg intramuscular or intravenous every 3 to 7 days; may increase to 200 mg per dose.

The terminal elimination half-life is approximately 5-6 hours for the iron-dextran complex, but the iron released from the complex has a half-life of 2-3 days due to incorporation into erythrocytes and storage pools.
Terminal half-life approximately 20-30 hours in patients with normal hepatic function; prolonged in hepatic impairment. Clinical context: supports every-3-week dosing.
Iron dextran is primarily excreted via the reticuloendothelial system; iron is incorporated into hemoglobin and stored as ferritin/ hemosiderin. Renal excretion of intact complexes is minimal (<1%). Fecal excretion accounts for less than 1% of the dose.
Primarily fecal (biliary excretion of iron from degraded RBCs, about 80-90%); renal excretion negligible (<5% unchanged).
