IRON DEXTRAN vs TRILITRON
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.
TRILITRON is a non-steroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis and thereby alleviating pain and inflammation.
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.
10 mg orally once daily, with or without food.

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 elimination half-life is 12-15 hours, allowing twice-daily dosing. Steady-state reached in 2-3 days.
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 renal excretion of unchanged drug (60-70%) and glucuronide conjugate (15-20%). Biliary/fecal elimination accounts for 10-15%.
