FERROUS FUMARATE vs TRIFERIC
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.
Triferic (ferric pyrophosphate citrate) is an iron replacement agent that delivers iron directly to transferrin via the sodium-dependent phosphate transporter, bypassing the reticuloendothelial system, thereby increasing iron availability for erythropoiesis without increasing ferritin levels.
Oral: 200 mg (equivalent to 65 mg elemental iron) three times daily. Adults: 325 mg (106 mg elemental iron) one to three times daily.
For iron deficiency anemia: 1 tablet (30 mg elemental iron as ferric pyrophosphate citrate) twice daily, 30 minutes before meals, administered orally.

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.
The terminal elimination half-life of ferric carboxymaltose is approximately 7-12 hours for the iron-carbohydrate complex. However, the clinical context involves redistribution of iron to stores and erythron, with a functional half-life of about 14-21 days for iron utilization.
Primarily fecal (about 90%) as unabsorbed iron; minor renal excretion (<1%) via sloughed intestinal cells and bile; negligible urinary elimination.
Ferric carboxymaltose is eliminated primarily via renal excretion of the iron-carbohydrate complex, with approximately 60-70% of the administered iron dose excreted in urine within 24 hours. The remaining 30-40% is retained in the body, incorporated into hemoglobin and iron stores, with minimal biliary or fecal excretion.
