Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Direct thrombin inhibitor that reversibly binds to the active site of thrombin, blocking its interaction with substrates, thereby inhibiting fibrin formation and activation of coagulation factors V, VIII, and XIII.
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.
1 mg/kg intravenous bolus followed by 0.1 mg/kg/hour continuous intravenous infusion for duration of procedure; alternatively, 0.75 mg/kg intravenous bolus followed by 1.75 mg/kg/hour continuous intravenous infusion for up to 4 hours during percutaneous coronary intervention.
80 units/kg IV bolus followed by 18 units/kg/hour continuous IV infusion; adjust to maintain aPTT 1.5-2.5 times control.

Terminal elimination half-life: 25-30 minutes in patients with normal renal function; increased to 2-3 hours in dialysis-dependent patients
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.
Renal: ~90% unchanged; biliary/fecal: negligible (<1%)
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%.
