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 sodium binds to antithrombin III (ATIII), inducing a conformational change that accelerates ATIII-mediated inactivation of factor Xa and thrombin (factor IIa), thereby inhibiting 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.
Initial IV bolus of 5000 units, followed by continuous IV infusion at 1300 units/hour (typically 25,000 units in 500 mL D5W at 26 mL/hour) for therapeutic anticoagulation; dose titrated to 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 approximately 1.5 hours (range 1–2 hours) after intravenous administration; dose-dependent: at therapeutic doses, half-life is about 1 hour; at higher doses, up to 2.5 hours. Clinical context: shorter half-life in pulmonary embolism, longer in renal impairment.
Renal: ~90% unchanged; biliary/fecal: negligible (<1%)
Renal: negligible; primarily metabolized by the liver and reticuloendothelial system; small amount excreted unchanged in urine (<5%). Biliary/fecal: minimal.
