摘要
将新疆膨润土纯化后研究了作为药用辅料的可行性。研究结果显示:该膨润土吸水膨胀性强(41.5±5.5倍于自身体积),粘度高(5%水分散液为70±30mPA·s),触变性良好,具一定的吸附性。无毒、无刺激性,铅、砷、汞合量低微(Pb:0.013%,As:0.002%,Hg:0.5μg/L),可望作为新型无机胶体药物辅料应用于各种药物制剂。通过在炉甘石洗剂、AI(OH)3;凝胶剂、阿司匹林片、不着色甲紫霜等剂型中的实际应用,充分证明其优异的助悬、崩解、载体性能,应用前景光明。
Abstract
We studied the feasibility of Xinjiang bentonite as a kind of pharmaceutical excipi-
ent after it was purified.The results showed thatthe bentonite had a higher swelling power in wa-ter(41.5±5.5ml).The viscosity of 5%water solution was 70±30mPa·s.It had good thixotropyand certain absorption.The bentonite was free from poison and stimulation,in which the content of Pb.As.Hg elements were tiny(Pb:0.013%.As:0.002%,Hg:2.5μg/L).Therefore.the ben-tonite can be applied into various pharmacies as a new kind of pharmaceutical excipient.Applied into calamin lotion,AI(HO)3 gel,asprin tablet,gentian violet cream etc,the bentonite can be used as an excellent suspending agent,disintgrant,and drug carrier.
