FERROUS FUMARATE vs PROFERDEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iron is an essential component of hemoglobin, myoglobin, and various enzymes; ferrous fumarate provides elemental iron for erythropoiesis and oxygen transport.
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.
Oral: 200 mg (equivalent to 65 mg elemental iron) three times daily. Adults: 325 mg (106 mg elemental iron) one to three times daily.
100 mg intramuscular or intravenous every 3 to 7 days; may increase to 200 mg per dose.

5-7 hours for iron in serum after absorption; terminal half-life of storage iron (ferritin) is approximately 6 days; clinical context: follows first-order kinetics with iron recycling.
Terminal half-life approximately 20-30 hours in patients with normal hepatic function; prolonged in hepatic impairment. Clinical context: supports every-3-week dosing.
Primarily fecal (about 90%) as unabsorbed iron; minor renal excretion (<1%) via sloughed intestinal cells and bile; negligible urinary elimination.
Primarily fecal (biliary excretion of iron from degraded RBCs, about 80-90%); renal excretion negligible (<5% unchanged).
