Eptifibatide

依替菲巴肽

Mechanism of action:

Eptifibatide 是一種血小板 GPIIb/IIIa 受體拮抗劑(glycoprotein IIb/IIIa inhibitor),為環狀七胜肽(cyclic heptapeptide)。GPIIb/IIIa(αIIbβ3)受體是血小板活化後表現於表面的關鍵受體,負責與纖維蛋白原(fibrinogen)或溫韋伯氏因子(von Willebrand factor)結合,形成血小板之間的橋接結構。Eptifibatide 能與 GPIIb/IIIa 受體結合,阻止纖維蛋白原與該受體結合並形成血小板橋接。
