Research on Preparation Technology of Xiaoer Qingfei Dispersible Tablets / 中国中医药信息杂志

ABSTRACT

Objective To optimize the prescription of preparation technology of Xiaoer Qingfei Dispersible Tablets. Methods The filler, disintegrant, adhesive, lubricant, and drug loading were screened by single factor tests. The combined application proportion of three disintegrating agents, PVPP, CMS-Na, and L-HPC, were optimized by orthogonal test. Results The best prescription of preparation technology of dispersible tabletsmicrocrystalline cellulose as filler;silica gel powder as lubricant;75%alcohol as the adhesive;PVPP, L-HPC, and CMS-Na as combined disintegrants (L-HPC∶PVPP∶CMS-Na=4∶3∶6). The disintegration time of prepared dispersible tablets was less than 3 minutes, and all through the No.2 sieve. Dispersible uniformity was in accordance with the provisions. Conclusion Xiaoer Qingfei Dispersible Tablets prepared by the optimized preparation process are stable and feasible, and suitable for clinical application.
