Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Heparin binds to antithrombin III, accelerating the inactivation of thrombin (factor IIa) and factor Xa, thereby inhibiting coagulation.
Heparin binds to antithrombin III, causing a conformational change that accelerates the inactivation of thrombin (factor IIa) and activated factor X (factor Xa), thereby inhibiting blood coagulation.
For therapeutic anticoagulation, administer intravenous bolus of 80 units/kg followed by continuous infusion at 18 units/kg/hour, adjusted to maintain aPTT 1.5-2.5 times control. For prophylaxis, 5,000 units subcutaneously every 8-12 hours.
80 units/kg IV bolus followed by 18 units/kg/hour continuous IV infusion; adjust to maintain aPTT 1.5-2.5 times control.

Mean terminal half-life 1.5 hours (range 1-2 hours) at therapeutic doses; dose-dependent (nonlinear) due to saturable clearance; prolonged in renal impairment (up to 3-6 hours) and hepatic disease.
Terminal elimination half-life is dose-dependent: at standard IV doses (100 U/kg), mean t½ = 60 min (range 40–90 min); at high doses (400 U/kg), t½ increases to 150 min due to saturable clearance mechanisms. Clinical context: Short t½ necessitates continuous infusion or frequent subcutaneous dosing for sustained anticoagulation.
Primarily hepatic and reticuloendothelial system metabolism; renal excretion of metabolites accounts for <50% of clearance; minimal biliary/fecal elimination.
Primarily renal excretion of metabolites (desulfated heparin) with a minor biliary/fecal component. Unchanged heparin is not excreted renally; clearance occurs via saturable hepatic metabolism and reticuloendothelial system uptake. Renal excretion accounts for approximately 50% of total clearance at therapeutic doses, while biliary/fecal elimination is <10%.
