Tirofiban is a synthetic, nonpeptide inhibitor acting at glycoprotein-(GP)-receptors, type IIb/IIIa, in human thrombocytes. It therefore constitutes an anticoagulant, specifically an inhibitor of thrombocyte aggregation.
The drug is marketed in many countries under the brand name Aggrastat® by either MSD Sharp & Dohme or Guilford.
