[摘要] 目的：通过选择合适辅料及适当的工艺方法，制备溶出度符合要求的头孢呋辛酯片。方法：考察包括淀粉、微晶纤维素、乳糖、羟丙纤维素钠、羧甲基淀粉钠、交联聚维酮、硬脂酸镁、滑石粉、十二烷基硫酸钠、聚维酮K30、微粉硅胶、2%HPMC水溶液、5%HPMC水溶液等辅料进行湿法制料压片、粉末直接压片对样品溶出的影响。结果：采用内外加法添加羧甲基淀粉钠，用微粉硅胶吸附原辅材料，湿法制粒压片，片芯迅速崩解为颗粒，然后再将其崩解为细粉，这样有利于颗粒继续崩解成细小颗粒，样品溶出度较为理想，符合质量标准要求。结论：该方法制备工艺简单，设备要求低，且成品合格率高，可用于头孢呋辛酯片的规模化生产。

[Abstract] Objective: To prepare the Cefuroxime Axetil Tablets with the dissolution rate meeting the requirements, by selecting the right auxiliary materials and appropriate processing methods. Methods: The impact of starch, microcrystalline cellulose, lactose, hydroxypropyl cellulose sodium, sodium carboxymethyl starch, cross-linked povidone, magnesium stearate, talc powder, lauryl sodium sulfate, povidone K30, aerosil, 2% HPMC aqueous solution, 5% HPMC aqueous solution and other auxiliary materials used in the wet process material tabletting and the powder direct tabletting on the sample dissolution were observed. Results: The internal and external addition method to add sodium carboxymethyl starch was used, the aerosil was used to absorb the raw auxiliary materials and the wet granulation to compress tablets, the tablet cores rapidly disintegrated into particles, then collapsed into fine powder, which was conducive to the disintegration of particles into fine particles. The sample dissolution rate was ideal and met the quality standards. Conclusion: The method has simple preparation process, low equipment requirements and high product qualification rate, and therefore can be used for the large-scale production of Cefuroxime Axetil Tablet.
