摘 要: 目的:采用新型崩解剂和稀释剂作为辅料,探讨猪苓多糖(polyporus polysaccharide,PPS)分散片处方的最佳配比,缩短其崩解时限,提高其生物利用度。方法:针对低取代羟丙基纤维素(low-substituted hydroxypropyl cellulose,L-HPC)、交联聚乙烯吡咯烷酮(polyvinylpolypyrrolidone,PVPP)、羧甲基淀粉钠(sodium carboxymethyl starch,CMS-Na)、微晶纤维素(microcrystalline cellulose,MCC)4种辅料设计正交试验,按照湿法制粒压片并做质量检查(崩解时限、外观、片重差异、脆碎度、溶出度),分析数据,总结最佳配比。结果:分散片的最佳处方工艺为以L-HPC、CMS-Na、PVPP、MCC作为联合崩解剂,L-HPC:CMS-Na:PVPP:MCC=11:8:5:5(质量比). 制得的分散片崩解时间<10 min. 结论:按该处方制备的PPS分散片工艺稳定可行,适于临床需要。

Abstract: Objective: We use new type of disintegrating agent and diluent to optimize the prescription of polyporus polysaccharide (PPS) dispersible tablet, in order to shorten its disintegration time and improve its bioavailability. Methods: According to the low-substituted hydroxypropyl cellulose (L-HPC), polyvinylpolypyrrolidone (PVPP), sodium carboxymethyl starch (CMS-Na), microcrystalline cellulose (MCC), we design the orthogonal test, use wet granulation, and check the quality of PPS dispersible tablet (appearance, tablet weight difference, disintegration time, brittle broken degree, dissolution). Then we analyze data and get the optimal proportion. Results: The best prescription of the dispersible tablets is as follows: L-HPC:CMS-Na:PVPP:MCC=11:8:5:5 (mass ratio). The disintegration time of the obtained dispersible tablets is less than 10 min. Conclusion: We obtain the best prescription of PPS dispersible tablets, which is stable and suitable for clinical use.
