ANGIOMAX vs PANWARFIN
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.
Anticoagulant that inhibits vitamin K epoxide reductase, thereby decreasing hepatic synthesis of vitamin K-dependent coagulation factors II, VII, IX, and X.
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.
5 mg orally once daily, adjusted to maintain INR 2-3.

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 20-60 hours (mean ~40 hours). Clinically, the longer half-life allows for once-daily dosing and steady-state is achieved in 5-7 days; anticoagulant effect may persist for 2-5 days after discontinuation due to depletion of vitamin K-dependent clotting factors.
Renal: ~90% unchanged; biliary/fecal: negligible (<1%)
Primarily renal as inactive metabolites; 60-92% of a dose is excreted in urine, with about 50% as the 7-hydroxywarfarin metabolite and the remainder as other metabolites. Biliary/fecal elimination accounts for approximately 10-20%.
