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 coagulation factors IIa (thrombin) and Xa, thereby preventing thrombus formation and extension.
5000 IU subcutaneously twice daily for prophylaxis; 5000 IU intravenous bolus followed by 800-1000 IU/hour continuous intravenous infusion for treatment.
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 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.
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.
Primarily renal, with 40-60% of the dose excreted unchanged in urine. Minor biliary/fecal elimination (<10%).
Renal: 50-70% as unchanged heparin and metabolites via saturable clearance; biliary/fecal: <5% as metabolites.
