【藥事知多D】一物兩用:Amantadine
一種藥往往可以有很多種不同的用途。
不過這些用途偶爾可能會風馬牛不相及。
例如Amantadine。
那Amantadine到底有什麼用途呢?
至於常用的用途主要一般有以下兩個:
一、帕金遜症(Parkinson's Disease)
雖然暫時還是不太清楚具體的作用原理,不過一般相信Amantadine能夠抑制NMDA受體(NMDA Receptors),主要適用於紓緩一些帕金遜症的症狀,例如運動徐緩(Bradykinesia)、僵硬(Rigidity)、震顫(Tremor)。
二、甲型流感病毒(Influenza A)
在藥理上,Amantadine主要透過阻斷甲型流感病毒的M2離子通道(M2 Ion Channel)和抑制病毒脫殼(Viral Uncoating),達到抗病毒的效果。
不過Amantadine較容易會出現抗藥性(Drug Resistance)。
實際上,只要一丁點兒的基因突變,例如點突變(Point Mutation),即僅僅改寫一個核苷酸(Nucleotide),便已經足以誘發交叉抗藥性(Cross-resistance)。[1]
在美國,隨著抗藥性愈來愈嚴重,現在Amantadine一般不再建議用來治療、預防流感。[1]
當然同一種藥,用途或許不同,不過副作用總會相同吧?
在副作用上,主要是頭暈、口乾、幻覺(Hallucination),偶爾還可能會誘發網狀青斑(Livedo Reticularis)。
看!Amantadine既是帕金遜藥,又是抗流感藥。這兩種用途是否有點牛頭不對馬嘴呢?
