Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Heparin binds to antithrombin III, inducing a conformational change that accelerates the inactivation of thrombin (factor IIa) and factor Xa, thereby inhibiting coagulation.
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.
Intravenous: Initial bolus of 80 units/kg (or 5000 units) followed by continuous infusion of 18 units/kg/h (or 1300 units/h), adjusted to maintain aPTT 1.5-2.5 times control. Subcutaneous: 5000 units every 8-12 hours for prophylaxis.

30–150 minutes (intravenous), dose-dependent; at therapeutic doses ~60 minutes; prolonged in hepatic disease.
0.5–2 hours (dose-dependent; at therapeutic doses, ~1–2 h; with higher doses, up to 2.5 h). Clinical context: shorter half-life in pulmonary embolism; prolonged in hepatic or renal impairment.
Renal: negligible; biliary/fecal: negligible; primarily cleared by hepatic depolymerization and reticuloendothelial system uptake.
Primarily cleared via reticuloendothelial system and metabolism; renal excretion of unchanged drug is minimal (<5%).
