Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Heparin binds to antithrombin III, accelerating its inhibition of thrombin (factor IIa) and factor Xa, thereby preventing fibrin clot formation.
Direct factor Xa inhibitor that selectively blocks the active site of factor Xa, inhibiting thrombin generation and thrombus formation.
Initial IV bolus of 80 units/kg, followed by continuous IV infusion at 18 units/kg/hour; subsequent dosing based on aPTT. For DVT/PE: initial bolus of 5,000 units or 80 units/kg, then 1,000-2,000 units/hour continuously.
15 mg orally twice daily for 21 days, then 20 mg orally once daily; for atrial fibrillation: 20 mg orally once daily with food; for VTE prophylaxis in hip or knee replacement: 10 mg orally once daily.

30–90 minutes (mean 1.5 h) for therapeutic doses; dose-dependent and saturable elimination: increases with dose (e.g., 100 U/kg: ~56 min; 400 U/kg: ~152 min). At lower doses, half-life may be shorter due to rapid clearance.
Terminal elimination half-life: 5–9 hours in young adults, 11–13 hours in elderly (≥65 years). Clinical context: Twice-daily dosing due to relatively short half-life; renal impairment prolongs half-life (up to 15 hours in severe impairment).
Renal: minimal intact heparin; primarily hepatic degradation via desulfation and depolymerization into inactive metabolites (uroheparin) excreted renally. Biliary/fecal: negligible (<1%).
Renal (36% as unchanged drug, 30% as inactive metabolites), fecal/biliary (33% as unchanged drug via hepatobiliary route). Total clearance is 10 L/h.
