Mechanism of Action



Aggrastat is a reversible antagonist of fibrinogen that binds to the glycoprotein IIb/IIIa receptor, thereby blocking the final common pathway to platelet aggregation.












Aggrastat HDB achieves >90% platelet aggregation inhibition
within 10 minutes.1,2


  • Platelet inhibition is reversible following cessation of infusion
  • The half-life of the HDB regimen is 2 hours and platelet aggregation returns to normal within 4 – 8 hours in approximately 90% of patients
