Amantadine

金剛烷胺

Mechanism of action:

一、Amantadine 能抑制 A 型流感病毒的 M2 蛋白離子通道(M2 proton channel),阻止病毒脫殼作用,使病毒 RNA 釋放進入細胞質的步驟受阻。但由於 A 型流感病毒已普遍出現對 amantadine 的抗藥性。 二、Amantadine 對於抗帕金森氏症的機制尚未完全清楚。Amantadine 可能促進多巴胺(dopamine)釋放並抑制其回收,提高基底核區域的多巴胺濃度。此藥物也能拮抗 NMDA(N-methyl-D-aspartate)受體,減少麩胺酸(glutamate)引起的興奮毒性(excitotoxicity)。
