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 thrombus formation and propagation.
5000 IU subcutaneously twice daily for prophylaxis; 5000 IU intravenous bolus followed by 800-1000 IU/hour continuous intravenous infusion for treatment.
IV: Initial bolus of 5000 units followed by continuous infusion at 1300 units/hour, adjusted based on aPTT. Typical infusion range 1000-2000 units/hour.

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.
30-60 minutes at therapeutic doses, dose-dependent (e.g., 100 U/kg yields t½ ~56 min; 400 U/kg yields ~152 min). At lower doses (e.g., 25 U/kg), t½ is ~30 min. Prolonged in hepatic or renal impairment.
Primarily renal, with 40-60% of the dose excreted unchanged in urine. Minor biliary/fecal elimination (<10%).
Primarily renal; metabolism by hepatic and reticuloendothelial system desulfation yields uroheparin, which is excreted in urine. Unchanged heparin is also excreted renally, with elimination proportional to dose and molecular weight. Biliary/fecal excretion is negligible (<5%).
