FRAGMIN vs HEPARIN SODIUM 10,000 UNITS AND DEXTROSE 5% IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fragmin (dalteparin) is a low molecular weight heparin that binds to antithrombin III, potentiating its inhibition of factor Xa and, to a lesser extent, thrombin, thereby preventing thrombus formation.
Heparin binds to antithrombin III, accelerating its inhibition of thrombin (factor IIa) and factor Xa, thereby preventing thrombus formation and propagation.
Deep vein thrombosis prophylaxis: 2500 IU subcutaneously once daily, starting 1-2 hours before surgery and continuing postoperatively for 5-10 days or until ambulatory. Treatment of acute DVT: 200 IU/kg subcutaneously once daily, or 100 IU/kg twice daily. Unstable angina/NSTEMI: 120 IU/kg subcutaneously every 12 hours (max 10,000 IU per dose) with aspirin.
IV: Initial bolus of 5000 units followed by continuous infusion at 1300 units/hour, adjusted based on aPTT. Typical infusion range 1000-2000 units/hour.

2-4 hours (anti-Xa activity) after subcutaneous administration; prolonged in renal impairment (creatinine clearance <30 mL/min: up to 6-12 hours)
30-60 minutes at therapeutic doses, dose-dependent (e.g., 100 U/kg yields t½ ~56 min; 400 U/kg yields ~152 min). At lower doses (e.g., 25 U/kg), t½ is ~30 min. Prolonged in hepatic or renal impairment.
Primarily renal excretion (up to 70% as unchanged drug via glomerular filtration); minor biliary/fecal elimination (<15%)
Primarily renal; metabolism by hepatic and reticuloendothelial system desulfation yields uroheparin, which is excreted in urine. Unchanged heparin is also excreted renally, with elimination proportional to dose and molecular weight. Biliary/fecal excretion is negligible (<5%).
