Upon administration, tirofiban antagonizes fibrinogen binding to the platelet cell surface receptor, glycoprotein (GP) IIb/IIIA complex, one of the two purinergic receptors activated by ADP. This prevents the GP IIb/IIIa receptor complex-mediated activation of adenylyl cyclase. This results in decreased levels of cAMP, interferes with the platelet membrane function and subsequent platelet-platelet interaction, prevents the release of platelet granule constituents and prolongs bleeding time."}]
