J Psychopharmacol:恐慌或焦虑时吸点阿米洛利粉剂,可能瞬间就管用

阿米洛利是临床常用的心衰治疗药物,也可用来降血压。近期一项临床前实验发现了这种药物的新用途:恐慌或焦虑时吸入用可以明显缓解症状。

阿米洛利是临床常用的心衰治疗药物,也可用来降血压。近期一项临床前实验发现了这种药物的新用途:恐慌或焦虑时吸入用可以明显缓解症状。

据报道,美国有4000万人存在焦虑症,大约600万人有恐慌症。治疗这些疾病的抗精神病药物不能立即缓解症状。

研究者指出,恐慌症的危险因素有很多,既有先天遗传因素,也可能是儿童期受到伤害,比如亲人亡故或分离,不仅可造成很深的心理阴影,也会改变儿童的基因。

他们将幼鼠从母代身边分离后,发现他们的表观遗传学发生了变化,即某些基因被关闭或打开。进一步研究发现,小鼠幼年时遭受的伤害会导致酸敏感离子通道1基因发生变化,这样它们会更容易感受到痛苦,对空气中的一氧化碳也呈现超敏反应。

研究者指出,这种生理变化会导致出现难以呼吸或过度通气的症状,即出现恐慌症。

基于这一发现,他们设想用一种酸敏感离子通道拮抗剂来缓解这种症状,于是阿米洛利成为实验品。

为了避免血脑屏障对药物吸收的影响,研究者选择以吸入的方式对小鼠给药,这样药物就会迅速进入大脑。很快小鼠的呼吸道症状就得到缓解。

研究者指出,该实验结果非常有前景,因此他们会尽快在临床环境中验证阿米洛利是否能缓解人的焦虑症状。
