Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Heparin binds to antithrombin III (ATIII) and accelerates its inhibition of thrombin (factor IIa) and other serine proteases (factors Xa, IXa, XIa, XIIa) in the coagulation cascade, thereby preventing fibrin clot formation.
Heparin binds to antithrombin III, accelerating its inhibition of coagulation factors IIa (thrombin) and Xa, thereby preventing thrombus formation and extension.
Continuous IV infusion: Initial bolus 80 units/kg, then 18 units/kg/hour; subsequent dose adjusted based on aPTT. Typical infusion rate: 20,000–40,000 units/24 hours.
Intravenous: Initial bolus of 80 units/kg followed by continuous infusion at 18 units/kg/hour; subcutaneous: 5000 units every 8-12 hours.

Terminal elimination half-life is 1-2 hours at therapeutic doses, dose-dependent: 30-60 min after IV bolus of 25 U/kg, increasing to 1.5-2.5 hours after 400 U/kg. Prolonged in hepatic/renal impairment and pulmonary embolism. Clinical context: continuous infusion achieves steady-state after ~4-6 hours.
Terminal elimination half-life: 1-2 hours (0.5-1.5 h at therapeutic doses, dose-dependent due to saturable clearance). Context: shorter half-life in pulmonary embolism, prolonged in hepatic/renal impairment. Protamine reversal used for rapid offset.
Heparin is eliminated primarily via hepatic metabolism and renal excretion. Approximately 50% of a dose undergoes hepatic desulfation and depolymerization to form uroheparin, which is excreted in urine. Unchanged heparin is cleared renally via saturable, dose-dependent mechanisms. Biliary/fecal elimination is negligible (<5%).
Renal: 50-70% as unchanged heparin and metabolites via saturable clearance; biliary/fecal: <5% as metabolites.
