發(fā)布時間:2019-04-23 22:45
【摘要】:目的:確定拉科酰胺骨架緩釋片的制備工藝,并進行體外釋放度評價。方法:以拉科酰胺為模型藥物,建立了拉科酰胺釋放度的測量方法,以羥丙基甲基纖維素(hydroxypropyl methyl cellulose,HPMC)為骨架材料加入各種輔料以濕法制粒壓片制備緩釋片。單因素試驗考察處方因素和工藝因素對藥物釋放的影響,星點實驗設(shè)計對處方進行優(yōu)化。結(jié)果:所制備的拉科酰胺骨架片體外釋放性能良好,可持續(xù)釋藥達12 h,符合實驗設(shè)計要求。結(jié)論:拉科酰胺骨架片的制備及體外釋放檢測方法簡便,結(jié)果可靠。
[Abstract]:Objective: to determine the preparation process of laconamide matrix sustained-release tablets and evaluate the release rate in vitro. Methods: a method for measuring the release of laconamide was established by using lakamide as a model drug. Hydroxypropyl methyl cellulose (hydroxypropyl methyl cellulose,HPMC) was used as a skeleton material to prepare sustained-release tablets by wet granulation with various excipients. The effects of prescription factors and technological factors on drug release were investigated by single-factor test, and the prescription was optimized by star-spot experiment. Results: the in vitro release of laconamide matrix tablets was good, and the sustained release was up to 12 h, which met the requirements of the experimental design. Conclusion: the method of preparation and in vitro release detection of laconamide scaffold tablets is simple and reliable.
