FERRLECIT vs PROFERDEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ferric carboxymaltose, a polynuclear iron(III)-hydroxide carbohydrate complex, provides a source of iron for hemoglobin synthesis and erythropoiesis. The iron is released to endogenous iron transport proteins, such as transferrin, and stored as ferritin or hemosiderin.
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.
125 mg elemental iron (5 mL) intravenously over 1-5 minutes or as infusion over 15-30 minutes, repeated as needed based on iron deficiency.
100 mg intramuscular or intravenous every 3 to 7 days; may increase to 200 mg per dose.

Sodium ferric gluconate has a terminal half-life of approximately 1 hour for the intact complex. However, after dissociation, iron is rapidly cleared from plasma with a half-life of about 6 hours. The clinical context: the short half-life minimizes free iron toxicity but requires frequent dosing for iron replacement.
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 is not excreted renally; elimination is primarily through fecal loss of unabsorbed iron (approximately 80-90% of orally administered iron) and minor desquamation of mucosal cells. After IV administration, iron is incorporated into hemoglobin and storage pools; minimal urinary excretion (<1%). Biliary excretion of iron is negligible.
Primarily fecal (biliary excretion of iron from degraded RBCs, about 80-90%); renal excretion negligible (<5% unchanged).
