Ziconotide

齊考諾肽
Mechanism of action:
Ziconotide 是一種 ω-型鈣離子通道抑制劑(N-type calcium channel blocker),屬於合成胜肽類,其結構源自僧袍芋螺(Conus magus)毒素。Ziconotide 會選擇性結合於脊髓背角(dorsal horn)初級感覺神經元突觸前膜上的 ω-型鈣離子通道(N-type calcium channel),阻止動作電位引發的鈣離子內流。鈣離子內流被抑制後,與疼痛傳導相關的神經傳遞物質釋放減少,包括麩胺酸(glutamate)、P 物質(substance P)、降鈣素基因相關肽(calcitonin gene-related peptide)等。
