ACCRUFER vs VENOFER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ACCRUFER (ferric maltol) is an oral iron replacement therapy. Ferric iron is complexed with maltol, which enhances absorption. Once absorbed, iron is utilized for hemoglobin synthesis and erythropoiesis.
Iron replacement therapy; iron is essential for hemoglobin synthesis and oxygen transport. VENOFER (iron sucrose) provides elemental iron that binds to transferrin for transport to erythroid precursor cells.
170 mg (1 tablet) orally twice daily (340 mg total daily dose) for adults with iron deficiency anemia, taken on an empty stomach at least 1 hour before or 2 hours after meals.
Adult: 5 mL (100 mg elemental iron) IV push at 1 mL/min or IV infusion over 15-30 minutes, given 1-3 times per week to a total cumulative dose based on iron deficit calculation using Ganzoni formula.

20 hours (prolonged in hepatic impairment)
5-6 hours (initial phase, redistribution); terminal half-life ~14 hours (iron clearance from plasma). Clinical context: reflects iron utilization and storage, not elimination of drug.
Renal 65% (as unchanged drug), fecal 35%
Primarily reticuloendothelial system; iron is incorporated into hemoglobin and stored as ferritin/hemosiderin. Minimal renal excretion (<1% unchanged). Fecal elimination negligible. Small amounts lost via desquamation, blood loss, and menstruation.
