Tirofiban is a selective platelet GPIIb/IIIa receptor antagonist with IC50 value of 9 nM, it inhibits platelet aggregation of gel-filtered platelets induced by 10 μM ADP.[1]
The GPIIb/IIIa receptor is a heterodimer composed of alpha and beta subunits. Each subunit consists of a larger extracellular region, a transmembrane domain, and a short intracellular cytoplasmic tail. There are over 80,000 GPIIb/IIIa receptors present on the plasma membrane of platelets. These receptors are relatively quiescent in the dormant platelet.[2]
In vitro, Tirofiban selectively inhibits the GP-IIb/IIIa receptor and have minimal effects on the ɑvβ3 vitronectin receptor. It inhibits platelet aggregation of gel-filtered platelets induced by 10 μM ADP with IC50 of 9 nM, but the IC50 for inhibition of human umbilical vein adhesion to vitronectin, which depends on ɑvβ3 vitronectin receptors, is 62 μmol/L. [1]
In vivo. Tirofiban inhibits platelet aggregation responses to ADP and collagen in canine models. When administered to humans at 0.15μg/kg/min for 4 h. Tirofiban produced a 2.5-fold increase in bleeding time and 97% inhibition of ADP-induced platelet aggregation. [3][4]
