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 (ATIII) and accelerates its inhibition of thrombin (factor IIa) and other serine proteases (factors Xa, IXa, XIa, XIIa) in the coagulation cascade, thereby preventing fibrin clot formation.
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.
Continuous IV infusion: Initial bolus 80 units/kg, then 18 units/kg/hour; subsequent dose adjusted based on aPTT. Typical infusion rate: 20,000–40,000 units/24 hours.

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 1-2 hours at therapeutic doses, dose-dependent: 30-60 min after IV bolus of 25 U/kg, increasing to 1.5-2.5 hours after 400 U/kg. Prolonged in hepatic/renal impairment and pulmonary embolism. Clinical context: continuous infusion achieves steady-state after ~4-6 hours.
Renal: ~90% unchanged; biliary/fecal: negligible (<1%)
Heparin is eliminated primarily via hepatic metabolism and renal excretion. Approximately 50% of a dose undergoes hepatic desulfation and depolymerization to form uroheparin, which is excreted in urine. Unchanged heparin is cleared renally via saturable, dose-dependent mechanisms. Biliary/fecal elimination is negligible (<5%).
