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 (ATIII) via a unique pentasaccharide sequence, inducing a conformational change that accelerates ATIII-mediated inactivation of factor Xa and thrombin (factor IIa). This prevents fibrin formation and clot propagation. It also inhibits factors IXa, XIa, and XIIa.
5000 IU subcutaneously twice daily for prophylaxis; 5000 IU intravenous bolus followed by 800-1000 IU/hour continuous intravenous infusion for treatment.
Continuous IV infusion: Initial bolus of 5,000 units, then 1,000 units/hour (25,000 units/24h) adjusted based on aPTT. Typical infusion rate 10-20 units/kg/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.
30–150 minutes (intravenous), dose-dependent; at therapeutic doses ~60 minutes; prolonged in hepatic disease.
Primarily renal, with 40-60% of the dose excreted unchanged in urine. Minor biliary/fecal elimination (<10%).
Renal: negligible; biliary/fecal: negligible; primarily cleared by hepatic depolymerization and reticuloendothelial system uptake.
