摘要:本文主要目的是为了改善吲哚美辛普通口服制剂的释药过程,减少毒副作用,提高患者顺应性,将制成吲哚美辛缓释片。以亲水性羟丙***纤维素作为骨架材料,采用湿法制粒压片制得,然后通过紫外分光光度计在320nm波长下考察其体外释放度,进行释药机制的研究。最后通过平行试验测定各处方在2h、6h、12h的累积释药量以及对其释药曲线的考察,经过处方筛选,最终优选得到最佳处方。结果表明采用处方
5所制备的缓释片具有良好的缓释效果,而且制备过程操作简单。

Abstract:The main purpose of this paper is to improve oral mon preparation process of drug release, reduce toxicity, the patients pliance, and will be made into Indomethacin Sustained-release tables. The wather-soluble hydrophilic matrix HPMC(K4) was used to prepare sustaind-release tablets by the wet pression technique. The content of the major drug was determined by UV spectrophotometry at 320nm, the release mechanic was studied by dete
