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 the inactivation of thrombin and factor Xa, thereby inhibiting coagulation cascade.
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.
Initial adult dose: 5,000 units IV bolus, followed by continuous IV infusion at 1,000–2,000 units/hour; or 10,000–20,000 units subcutaneously every 12 hours. Dose adjusted based on aPTT.

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.
Mean 1.5 hours (range 1-2 hours) after IV administration; increases with dose (e.g., 25,000 U IV: ~2.5 h). Clinical context: nonlinear pharmacokinetics; half-life prolonged in hepatic or renal impairment.
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%).
Primarily renal (heparin is metabolized and excreted as uroheparin and other metabolites; up to 50% of administered dose appears in urine as unchanged heparin, but clearance is dose-dependent and nonlinear).
