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, inducing a conformational change that accelerates the inactivation of thrombin (factor IIa) and factor Xa, 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.
Intravenous: Initial bolus of 80 units/kg (or 5000 units) followed by continuous infusion of 18 units/kg/h (or 1300 units/h), adjusted to maintain aPTT 1.5-2.5 times control. Subcutaneous: 5000 units every 8-12 hours for prophylaxis.

Terminal elimination half-life: 25-30 minutes in patients with normal renal function; increased to 2-3 hours in dialysis-dependent patients
0.5–2 hours (dose-dependent; at therapeutic doses, ~1–2 h; with higher doses, up to 2.5 h). Clinical context: shorter half-life in pulmonary embolism; prolonged in hepatic or renal impairment.
Renal: ~90% unchanged; biliary/fecal: negligible (<1%)
Primarily cleared via reticuloendothelial system and metabolism; renal excretion of unchanged drug is minimal (<5%).
