ANGIOMAX RTU vs HEDULIN
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 (fibrinogen, factor V, VIII, XIII, and protein C).
HEDULIN (phenindione) is an anticoagulant that inhibits vitamin K-dependent synthesis of coagulation factors II, VII, IX, and X in the liver, thereby reducing thrombus formation.
1 mg/kg intravenous bolus, followed by 0.15 mg/kg/min continuous intravenous infusion for up to 4 hours during percutaneous coronary intervention (PCI). For patients with heparin-induced thrombocytopenia (HIT) undergoing PCI, bolus 0.75 mg/kg, then 1.75 mg/kg/hour infusion for 4 hours.
Oral, 200-400 mg initially, then 100-200 mg every 6-12 hours; maximum daily dose 1200 mg.

The terminal elimination half-life of bivalirudin is approximately 25 minutes in patients with normal renal function. In patients with moderate to severe renal impairment, the half-life is prolonged (e.g., up to 1 hour in patients with creatinine clearance <30 mL/min, and up to 3-4 hours in dialysis-dependent patients). This is clinically relevant for dosing adjustments and monitoring of anticoagulation.
Terminal elimination half-life is 18-24 hours in patients with normal renal function; may be prolonged to 30-40 hours in renal impairment, necessitating dose adjustment.
Bivalirudin is cleared by a combination of renal elimination (approximately 20% unchanged in urine) and proteolytic cleavage (hepatic metabolism and other proteases). Renal clearance accounts for about 20% of total clearance. Fecal excretion is negligible (<1%).
Renal excretion of unchanged drug accounts for approximately 70% of elimination; the remainder is metabolized hepatically and excreted in feces via bile.
