Glycoprotein IIb/IIIa inhibitors

In medicine, a glycoprotein IIb/IIIa inhibitors, also GpIIb/IIIa inhibitors, is class of antiplatelet agents.

Several GpIIb/IIIa inhibitors exist:

  • abciximab (ReoPro)
  • eptifibatide (Integrilin)
  • tirofiban (Aggrastat)


Glycoprotein IIb/IIIa inhibitors are frequently used during percutaneous coronary interventions (angioplasty with or without intracoronary stent placement).

They work by preventing platelet aggregation and thrombus formation. They do so by inhibition of the GpIIb/IIIa receptor on the surface of the platelets.


Their development arose from the understanding of Glanzmann's thrombasthenia, a condition in which the GpIIb/IIIa is lacking.[1]
