Haloperidol

氟哌啶醇
Mechanism of action:
Haloperidol 是一種丁醯苯類(butyrophenone)衍生物。Haloperidol 能阻斷中腦邊緣通路(mesolimbic pathway)中的 D₂ 受體,減少多巴胺過度活化,從而減少幻覺、妄想、思考混亂。Haloperidol 亦會影響其他多巴胺通路,比如黑質紋狀體通路(nigrostriatal pathway),易產生錐體外症狀(extrapyramidal symptoms,EPS);結節漏斗通路(tuberoinfundibular pathway),抑制多巴胺對泌乳素的抑制作用,導致高泌乳素血症(hyperprolactinemia)。
