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), thereby preventing fibrin clot formation and extension.
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.
Loading dose: 5000 units IV bolus, then continuous IV infusion at 12,000-18,000 units/24h (10-15 units/kg/h). Adjust to target aPTT 60-80 seconds.
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.

The terminal elimination half-life of heparin is dose- and concentration-dependent, averaging 1-2 hours after intravenous administration. At therapeutic doses, the half-life is approximately 1.5 hours; with higher doses, it can extend to 2.5-3 hours. The half-life is prolonged in patients with hepatic or renal impairment.
1-2 hours (dose-dependent; prolonged with higher doses, renal impairment, or in elderly).
Heparin is eliminated primarily via the reticuloendothelial system and liver, with renal excretion of metabolites accounting for approximately 50-60% of the dose. A small fraction (up to 5%) is excreted unchanged in urine. No significant biliary or fecal elimination.
Renal (predominantly via reticuloendothelial system and liver metabolism; unchanged drug excreted in urine).
