Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Heparin binds to antithrombin III, inducing a conformational change that accelerates the inhibition of thrombin (factor IIa) and activated factor X (Xa). This prevents the conversion of fibrinogen to fibrin and inhibits clot formation.
Heparin potentiates the activity of antithrombin III, thereby inactivating thrombin (factor IIa) and activated factor X (Xa), and preventing fibrin clot formation. It also inhibits factors IXa, XIa, and XIIa.
Continuous intravenous infusion: initial bolus 80 units/kg (max 10,000 units) followed by infusion at 18 units/kg/hour (usual adult dose 1,000-2,000 units/hour). For prophylactic use: subcutaneous 5,000 units every 8-12 hours.
10-100 units/mL solution; flush intermittent intravenous catheters after each use with 1-5 mL; for central venous catheters, use 2-3 mL of 10 units/mL solution; for peripheral catheters, use 1-2 mL of 10 units/mL solution.

Dose-dependent: 30–60 min after 25 U/kg IV, 60–90 min after 100 U/kg IV, 150 min after 400 U/kg IV. Terminal half-life: ~1.5 h (low dose) to ~5 h (high dose). Context: nonlinear due to saturable clearance mechanisms.
1-2 hours (dose-dependent; prolonged with higher doses, renal impairment, or in elderly).
Renal (minimal, saturable) and reticuloendothelial system (heparinase). Unchanged heparin: negligible urinary excretion. Metabolites: desulfated heparin via hepatic and extrahepatic heparinase; inactive fragments cleared renally.
Renal (predominantly via reticuloendothelial system and liver metabolism; unchanged drug excreted in urine).
