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), thereby preventing clot formation and extension.
Heparin binds to antithrombin III, accelerating its inhibition of coagulation factors IIa (thrombin) and Xa, thereby preventing thrombus formation and extension.
IV continuous infusion: initial bolus 80 units/kg, then maintenance 18 units/kg/hour; titrate to aPTT 1.5-2.5 times control. The solution HEPARIN SODIUM 10,000 UNITS IN DEXTROSE 5% is typically used for continuous infusion; dose should be adjusted based on patient weight and aPTT.
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 1.5-2 hours (mean 1.6 h) at therapeutic doses, but is dose-dependent: 30-60 min after 25 U/kg, 1-2 h after 100-200 U/kg, and 2.5-5 h after 400-800 U/kg. Half-life is prolonged in hepatic or renal impairment.
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.
Heparin is eliminated primarily via the reticuloendothelial system and renal excretion. Approximately 50% is excreted unchanged in urine via saturable zero-order kinetics, with the remainder metabolized to uroheparin and other inactive metabolites. Biliary/fecal excretion is negligible (<5%).
Renal: 50-70% as unchanged heparin and metabolites via saturable clearance; biliary/fecal: <5% as metabolites.
