杜笙药用辅料入驻北京华豫清源贸易有限公司，为公司的经营范围又扩大了许多。

      杜笙树脂 有４种关于制药业配方的应用。
TULSION® resins find a number of applications as Excipients in Pharmaceutical Formulations .

应用 / Applications

杜笙树脂于药品的应用大致可以分为以下４大类别 :
The use in pharmaceutical formulations can be classified under one of the following four categories

<味道包覆剂> – 一些药物含有苦味 ,可用杜笙交换树脂来吸收此苦味而相对比较没苦味。人的口中及胃的酸碱值 （pH）大约是在相同的范围 ,因此药品不会在口中溶解而只在胃里溶解。因此,当药经过口中时 ,药品的结构仍处于错化物 ，没有任何的味道被释出。不同的树脂选择来包含苦味,取决于药品特性 （请连络我们以取得更详细资料）。
<Taste Masking Agent> – Certain drugs that have a very bitter taste can be made relatively tasess by adsorbing the drugs on Tulsion Exchange Resins . The pH in the mouth being on the basic side compared to the pH in the stomach , the complex drug will not be released in the mouth but only in the stomach. Since while passing through the mouth the drug remains in the complex form , none or very little taste is imparted. The nature of resin used is dependent upon the type of drug being masked （please contact us for more details）.

<药片溶解剂> - 为了确保一旦药片摄入，能提供所需的药物。一样的药片剂 ，一样的迅速溶解是可以达到的。外用试剂添加到药片配方，以确保药片溶解。TULSION®树脂可被当成是药剂溶解剂。这是由于树脂会比树脂处于氢﹑钾的 “Polacrilin钾” 树脂的形式容易膨胀，因而成为在这个应用程序的形式树脂。
<Tablet Disintegrant> – In order to ensure that once a tablet is ingested , the desired drug is delivered . It is desirable that the tablet disintegrates uniformly and quickly. External agents are added to a tablet formulation to ensure the disintegration. TULSION® resins ca be used as a disintegrating agent. This is due to the fact that the resin will swell than the resin in hydrogen form , Potassium form of the resin “Polacrilin Potassium” is preferred in this applications.


<药效持续释放> -缓释剂是要确保药物不断的 ,慢慢的，但稳定的速度被释放到身体。药剂从离子交换树脂释放是 取决于身体内不同液体与药品及树脂错化物之间的反应来决定。对药物的释放速度可通过改变控制粒子的大小，树脂交联的程度及树脂的化学性质。此种持续性的释放药效配方是可以依照不同的应用而量身订作的。
<Sustained Release> – Sustained release formulations ensure that the drug is released continuously into the body at a slower , but steady rate. The release of durgs from ion exchange resins depends upon a series of ionic reactions between various body fluids and drug – resin complex . The rate of release of drugs can be controlled by varying the particle size , degree of cross-linking and the chemistry of resin. The release profile can almost be tailor made to suit a particular application.

<药效稳定药物> - 例如药物，* – 12的存储时，经过一段时间会慢慢分解。此类药物的稳定可藉由使用TULSION®树脂来达成。
<Drug Stabilization> – Drugs for instance, Vitamin B-12 when stored , degenerate after some time. The stabilization of such drugs can be brought about using Tulsion resins.

TULSION®杜笙树脂 是经过美国药品管理局认证通过 ，并具有 ISO 9001 及ISO 14001 的品质认证。
