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 potentiates the activity of antithrombin III, inactivating thrombin and activated factor X (FXa), thereby preventing fibrin formation and thrombus propagation.
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.
10-100 units/mL solution, 1-2 mL flush intravascularly after each catheter use or daily when catheter is not in use; typical adult dose: 10-100 units per flush.

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 approximately 1-2 hours (mean 1.5 hours) at therapeutic doses; increases with dose; in renal failure, half-life prolonged up to 3-5 hours; clinical note: duration of effect short due to rapid clearance, requiring continuous infusion or frequent dosing.
Renal: ~90% unchanged; biliary/fecal: negligible (<1%)
Primarily renal via glomerular filtration and tubular secretion; about 50% excreted unchanged in urine; remainder metabolized in the liver and reticuloendothelial system (heparinase); fecal elimination negligible (<5%).
