Amoxapine

阿莫沙平

Mechanism of action:

Amoxapine 是一種三環抗憂鬱藥(tricyclic antidepressant),屬於二苯並氧氮䓬類(dibenzoxazepine)衍生物。Amoxapine 主要抑制正腎上腺素轉運蛋白(norepinephrine transporter)對正腎上腺素(norepinephrine)的回收,使突觸間隙中正腎上腺素濃度上升;對血清素轉運體(serotonin transporter) 的抑制作用相對較弱。Amoxapine 及其活性代謝物(特別是 8-hydroxyamoxapine)可拮抗多巴胺 D₂ 受體。Amoxapine 亦會拮抗 H₁ 組織胺受體、毒蕈鹼型乙醯膽鹼受體(muscarinic acetylcholine receptor)、α₁-腎上腺素受體,是引發副作用的來源。
