治療癲癇的另類思維:併用克拉維酸與丙戊酸

摘要


癲癇的病理原因包括興奮性麩胺酸(glutamate)神經系統活性過高及抑制性(γ-aminobutyric acid, GABA)神經系統活性不足所致。丙戊酸(valproic acid)是廣效性抗癲癇藥物,其藥理機制包括提升GABA之濃度,但是在治療劑量下仍有三分之一的患者對此藥物的反應不佳,甚至出現神經與精神副作用。克拉維酸(clavulanic acid)可以促進麩胺酸轉運蛋白-1(glutamate transporter-1)之表現,推論可以清除過多的麩胺酸,降低神經過度興奮,具有抑制癲癇發作之潛力。因此合併投予克拉維酸與丙戊酸,可能可以達到抑制癲癇發作的相乘效果。
