| In vitro study | Tirofiban (MK-383, Aggrastat) is a non-peptide derivative of tyrosine that selectively inhibits the GP-IIb/IIIa receptor and has the lowest effect on the vβ3 Vitronectin receptor. Tirofiban inhibited gel-filtered platelet aggregation induced by 10 μm ADP with an IC50 of 9 nM, but inhibited human umbilical vein adhesion to Vitronectin with an IC50 of 62 μmol/L, this is dependent on the vβ3 receptor. |
| In vivo study | Tirofiban(10 to 500 mg/kg or 10 micrograms/kg/min continuous intravenous infusion for 360 minutes) inhibits platelet aggregation with ADP and collagen in the canine model. Treatment of humans with Tirofiban at 0.15 μg/kg/min for 4 hours increased bleeding time 2.5-fold and inhibited 97% of ADP-induced platelet aggregation. |
