摘要
目的:制备丹参酚酸速释微丸,并对制备工艺进行研究。方法:考察了处方中润湿剂、载药量、辅料、乳糖用量、崩解剂、羧甲基淀粉钠用量以及润湿剂用量等因素对丹参酚酸微丸收率、圆整度、溶出度的影响;采用正交试验设计,筛选出丹参酚酸速释微丸的最佳制备工艺。结果:丹参酚酸速释微丸处方以总量50 g计算,主药22.5g,乳糖5 g,羧甲基淀粉钠2 g,微晶纤维素20.5 g,润湿剂为30%的乙醇27 mL。采用挤出滚圆法制备,最佳工艺条件为挤出频率25 Hz,滚圆频率50 Hz,滚圆时间4 min。结论:丹参酚酸速释微丸制备工艺科学合理,制剂稳定,为通脉复方微丸多元释药系统的制备奠定了基础。
Objective:To prepare Danshen phenolic acid fast release micro-pellets and study its preparation craft.Methods: The factors which could impact yield,extrude shaping,dissolution of Danshen phenolic acid micro-pellets such as wetting agent,drug loading dose,adjuvant,lactose dose,disintegrant,CMS-Na dose and wetting agent dose was investigated.The optimum preparation craft of Danshen phenolic acid fast release micro-pellets was screened out by orhogonal design.Results: Formula of Danshen phenolic acid fast release micro-pellets was calculated as volume dose 50 g.The formula was as follows: principal agent 22.5 g,lactose 5 g,CMS-Na 2 g,MCC 20.5 g,27 mL 30%ethanol as wetting agent.Extrusion-spheronization was applied.The optimum conditions were screened out as follows:extrusion frequency(25 Hz),spheronization machine frequency(50 Hz),spheronization time(4 min).Conclusion: The process was scientific and rational.The preparation is stable settles basis for multi-drug delivery system of Tongmai micro-pellets.
