Nature COMMUN:解决多病者吃药的痛苦,新技术可以把一堆药打印到一张“糖果纸”上

2017-09-29 佚名 36 氪

吃药是一个痛苦的事情。最痛苦的事情还不在于药片的苦,而在于,一下子吃很多种药(比如说七八种)的话,拿这个药片那个胶囊的,很麻烦,如果上班的话,带着一堆药瓶子去公司,就更麻烦,时间一久,光吃药的麻烦劲儿就会让人厌倦,所以病没全好,有时候就把药停了。从小体弱多病的我,在这一点上深有感触。基于这种多病属性,密歇根大学研究人员开发的一种新技术,引起了我的兴趣。这种技术可以将多种药物打印在一次性的条装带或者



吃药是一个痛苦的事情。

最痛苦的事情还不在于药片的苦,而在于,一下子吃很多种药(比如说七八种)的话,拿这个药片那个胶囊的,很麻烦,如果上班的话,带着一堆药瓶子去公司,就更麻烦,时间一久,光吃药的麻烦劲儿就会让人厌倦,所以病没全好,有时候就把药停了。

从小体弱多病的我,在这一点上深有感触。

基于这种多病属性,密歇根大学研究人员开发的一种新技术,引起了我的兴趣。这种技术可以将多种药物打印在一次性的条装带或者贴片上,就像糖果纸那样。这项成果已经发表在《自然》的子刊《自然—通信》上。

在测试中,这些药物和传统的药物一样有效,可以破坏培养的癌细胞。关键的是,这种技术同时打印多种药物,对于每天服用很多处方药的患者来说,这要方便得多。

把需要吃的药打印到一张贴片上,一饮而尽,确实比来回开药瓶子要简洁很多,而且,去公司的话,不用带一堆药瓶子随身,这一点对上班族来说有更大的实用性。

这种技术的初衷本身也是如此:希望提高患者的依从性,老老实实地遵医嘱把该吃的药按时按量吃了。对于小孩来说,有了这种技术,给他们喂药的麻烦也要减少很多。

此外,它可以让药品更容易被运送到困难的地区,比如战区或农村地区,因为有些药品按照常规保存方法,在运输过程中很难让它们保持稳定。

而大肆宣传的个性化医疗也要求有一种简单、低成本、本地化的方式,来生产针对个人的少量物质。

因此,理论上说,这种技术也拥有个性化医疗的应用前景。

研究人员使用了“蒸汽喷射打印”(vapor jet printing)技术,来开发他们的新药物制造技术。这使得高分辨率的打印,能够被精确地打印到一个精细的晶体结构上。

具体来说,在这种技术中,活性成分被蒸发掉,然后再与一股像氮气这样样的惰性气体混合在一起。随后,药物会随气体一起传播,然后在冷却的表面凝结成一层薄薄的结晶膜。

这种排列会使得药物的溶解变得更加容易。

当然,这项技术还需要数年时间,才能打印出面向大众的药物。

不过,短期内,它可能会开始在制药公司内部使用,这些公司可以利用这种贴片技术,快速药物生产来加速临床试验。

制药公司面临的主要挑战之一是对人类临床测试的速度,这项技术为加快新药的评估提供了一种新的方法。

但是研究人员希望,有一天,这项技术可以在像糖果纸一样的卷纸上打印大量的药物。

听起来很美好的样子哦。

不过,还是祝愿大家、也祝愿我自己远离疾病吧。就我个人经验来说,生病这种事,只能是病好了之后给别人提供段子,让大家开心一下,可是这种生产段子的方式效率太低了,费时费力折磨身体还花钱,实在犯不上。看别人倒霉也一样可以创造段子嘛,为什么非要自己倒霉呢,对吧?

所以,还是健健康康地活着吧,身体倍儿棒,呼吸吐纳之间,感觉风清月朗、碧海长空,挺好。
