杜笙樹(shù)脂 有4種關(guān)于制藥業(yè)配方的應(yīng)用。 TULSION? resins find a number of applications as Excipients in Pharmaceutical Formulations .
應(yīng)用 / Applications
杜笙樹(shù)脂于藥品的應(yīng)用大致可以分為以下4大類(lèi)別 : The use in pharmaceutical formulations can be classified under one of the following four categories
<味道包覆劑> – 一些藥物含有苦味 ,可用杜笙交換樹(shù)脂來(lái)吸收此苦味而相對(duì)比較沒(méi)苦味。人的口中及胃的酸堿值 (pH)大約是在相同的范圍 ,因此藥品不會(huì)在口中溶解而只在胃里溶解。因此,當(dāng)藥經(jīng)過(guò)口中時(shí) ,藥品的結(jié)構(gòu)仍處于錯(cuò)化物,沒(méi)有任何的味道被釋出。不同的樹(shù)脂選擇來(lái)包含苦味,取決于藥品特性 (請(qǐng)連絡(luò)我們以取得更詳細(xì)資料)。 – Certain drugs that have a very bitter taste can be made relatively tastele y 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).
<藥片溶解劑> - 為了確保一旦藥片攝入,能提供所需的藥物。一樣的藥片劑,一樣的迅速溶解是可以達(dá)到的。外用試劑添加到藥片配方,以確保藥片溶解。TULSION?樹(shù)脂可 被當(dāng)成是藥劑溶解劑。這是由于樹(shù)脂會(huì)比樹(shù)脂處于氫﹑鉀的 “Polacrilin鉀” 樹(shù)脂的形式容易膨脹,因而成為在這個(gè)應(yīng)用程序的首選形式樹(shù)脂。 – 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? resin
