Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Unfractionated heparin (UFH) potentiates antithrombin III (ATIII) activity, leading to inhibition of factor Xa and thrombin (factor IIa). It also binds to heparin cofactor II, inhibits platelet aggregation, and increases vascular permeability.
Heparin binds to antithrombin III, accelerating its inhibition of thrombin (factor IIa) and factor Xa, thereby preventing fibrin clot formation.
5000 IU subcutaneously twice daily for prophylaxis; 5000 IU intravenous bolus followed by 800-1000 IU/hour continuous intravenous infusion for treatment.
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.

Terminal elimination half-life is approximately 1.5 hours (subcutaneous) after a 5000 IU dose. With therapeutic doses (e.g., 15,000 IU/24h), half-life may prolong to 2-3 hours. Clinical context: Half-life is dose-dependent and increases with heparin clearance saturation.
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.
Primarily renal, with 40-60% of the dose excreted unchanged in urine. Minor biliary/fecal elimination (<10%).
Renal: minimal intact heparin; primarily hepatic degradation via desulfation and depolymerization into inactive metabolites (uroheparin) excreted renally. Biliary/fecal: negligible (<1%).
