Goserelin

戈舍瑞林

Mechanism of action:

Goserelin 是一種促性腺激素釋放激素(gonadotropin-releasing hormone)的類似物,屬於合成胜肽類(synthetic peptide analogue)。在初期,goserelin 會持續刺激腦下垂體前葉的促性腺激素釋放激素受體(GnRH receptor),使黃體成長激素(LH)與濾泡刺激素(FSH)短暫上升,造成性荷爾蒙(睪酮或雌激素)暫時增加。隨著持續提供,促性腺激素釋放激素受體因長期刺激而發生去敏感化與數量下降,腦下垂體對促性腺激素釋放激素反應明顯減弱,使黃體成長激素和濾泡刺激素開始減少,進而降低性荷爾蒙產量。
