Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Heparin binds to antithrombin III, inducing a conformational change that accelerates the inhibition of thrombin (factor IIa) and activated factor X (Xa). This prevents the conversion of fibrinogen to fibrin and inhibits clot formation.
Heparin binds to antithrombin III, inducing a conformational change that accelerates the inactivation of thrombin (factor IIa) and factor Xa, thereby inhibiting coagulation.
Continuous intravenous infusion: initial bolus 80 units/kg (max 10,000 units) followed by infusion at 18 units/kg/hour (usual adult dose 1,000-2,000 units/hour). For prophylactic use: subcutaneous 5,000 units every 8-12 hours.
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.

Dose-dependent: 30–60 min after 25 U/kg IV, 60–90 min after 100 U/kg IV, 150 min after 400 U/kg IV. Terminal half-life: ~1.5 h (low dose) to ~5 h (high dose). Context: nonlinear due to saturable clearance mechanisms.
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 (minimal, saturable) and reticuloendothelial system (heparinase). Unchanged heparin: negligible urinary excretion. Metabolites: desulfated heparin via hepatic and extrahepatic heparinase; inactive fragments cleared renally.
Primarily cleared via reticuloendothelial system and metabolism; renal excretion of unchanged drug is minimal (<5%).
