从中药滥改剂型看中医的数典忘祖


现代药品为什么要制成某种剂型,这是有严格试验的,为什么做成片剂,为什么做成注射剂,都能找到原因(专利期内的盗版药、出专利期的仿造药不一定找得到原因-_-b),甚至某种成分原来是25mg一片每次口服两片,想改成50mg一片每次口服一片,都要重新进入临床试验,重新走一遍可能长达数年的审批路径,不是随意说改就改的。
而中药呢?
在败毒百科搜了下,中药的剂型有几十种,先摘几个传统的来:
  1. 汤剂:把药物混均,加水煎煮后,去渣留汁,注意是去渣后的汤水,不吃药渣的。据说汤汤水水的吸收快,便于加减使用,能全面、灵活地照顾到每个病人或各种病证的特殊性,但不便于携带。适用于一般疾病或急性病证。
  2. 丸剂:把药物碾研成细末,加蜂蜜或面糊之类的辅料固定成型,号称吸收缓慢,药力持久,便于携带和贮存,但奏效较慢。(可是武侠小说却喜欢用这玩意儿急救,搞毛?)
  3. 散剂:把药物研成均匀干燥粉末,直接使用。它的特点是制作简便,便于服用和携带,节约药材等,吸收率据说夹在汤剂和丸剂之间,看来这才是王道。
  4. 还有几十种,不摘了-_-b
现在市面上的中药之所以有特权免于任何安全性和有效性的检验,理由就是它们是按照古籍记载做出来的,古人都没事今人当然可以用。姑且不管这个理由有多荒谬,至少,按照古籍记载,这是底线吧?
但是看看今天的中药,有几个是按照古籍记载做出来的?先说中药材,什么什么不省人工的,现在的炮制手段有几个跟古籍记载的一致?要知道,炮制是理化过程,改变了原药材的理化性质,而理化性质是药物最基本也是最关键是因素你能不关心?别说实验室都做不到理化因素一致,哪个中药师能控制得准?就算有这个神人,全国有几个,全国的病人都找他?按照古籍标准,作为每名都可能生病的公民,为什么不监督一下?
再说到中成药,那就是彻彻底底的数典忘祖了——哪本中医典籍上记载过中成药了?
  1. 首先,冲剂,似乎是古代散剂的现代用法,区别是加了水。问题是,加水会不会影响散剂的药效,这个谁说都不算,得试验啊,怎么可以不经过试验就贸贸然改变祖宗的药物剂型,只为了申请一个新药的批号?
  2. 其次,片剂,这个似乎是古代散剂和丸剂的改造版,有的人说也可能是汤剂的改造版,问题是人家丸剂和散剂好歹是固体药渣做的,汤剂是汤汤水水片剂是固体,怎么改造?哦,我倒是想到一招,把汤汤水水的蒸干,留下汤剂里溶解的药物成分,这下可以做成片剂了,问题是蒸干过程的理化改变肯定非常严重,这些成分是否依然有效,凭什么不需检验?
  3. 还有,胶囊。现代药物之所以做成胶囊,要么为了缓释,要么为了肠溶,决不是没来由的多此一举。中药呢?中药也许有缓释一说,肠溶是绝对没有的。那么,缓释的效果和丸剂相比如何,是不是要重新检验一番,要不然太缓太急了都会影响疗效,对患者不利啊~至于肠溶嘛,如果有中成药宣称肠溶,那一定是为了变造新药买高价,连遮羞的借口都没有。
  4. 最后,竟然还有天杀的注射剂,杀人不见血!从古至今有哪一本中医书记载中药可以注射了?且不说摄入胃肠道的微小蛋白质或多肽都可能引起严重的反应,把成分不明的物质跳过胃肠的过滤直接注入血管,是怕人死得不够快么?对这种特殊的“中药”都不允许检验才是过分啊!连成分都不搞清楚,还不如打鸡血呢。。。
综合来看,中成药不是为了方便患者,而是为了方便厂商不断变换剂型申请新药批号卖新的更贵的价钱——如果真为患者着想应该是研究更真实体现中医典籍的药材,而不是与典籍无关的新兴剂型。

I comment each time I like a post on a site or if I have something to valuable
to contribute to the conversation. Usually it's a result of the fire displayed in the article I browsed. And on this article "从中药滥改剂型看中医的数典忘祖". I was actually excited enough to leave a thought :-P I do have a couple of questions for you if it's okay.

Is it simply me or do a few of these remarks look like they are coming from brain dead visitors?

:-P And, if you are posting at additional sites, I'd like to keep up with anything fresh you have to post. Would you list every one of all your social sites like your twitter feed, Facebook page or linkedin profile?
