摘 要:目的:优选甲磺酸培氟沙星分散片处方并考察其体外溶出度。方法:对处方中选用的微晶纤维素、交联聚乙烯吡咯烷酮、羧甲基淀粉钠和聚乙烯吡咯烷酮用量进行正交试验;采用紫外分光光度法考察甲磺酸培氟沙星分散片与普通片的溶出度。结果:优选的最佳处方为微晶纤维素20%、交联聚乙烯吡咯烷酮6%、羧甲基淀粉钠5.5%和聚乙烯吡咯烷酮8%。所制分散片在30s内完全崩解,15min时溶出度明显高于普通片。结论:采用本处方及工艺制得的甲磺酸培氟沙星分散片质量可靠,崩解时限短,体外释放度优于普通片。OBJECTIVE: To optimize the formulation of pefloxacin mesylate dispersible tablets by orthogonal design, and to evaluate its dissolution characteristics in vitro.METHODS: An orthogonal experiment was conducted to identify the amounts of microcrystalline cellulose, cross-link polyvinyl pyrrolidone, sodium carboxymethyl starch and polyvinyl pyrrolidone se- lected for the formulation of pefloxacin mesylate dispersible tablets. UV spectrophotometric method was used to examine the dissolutions of pefloxacin mesylate dispersible tablets and common tablets. RESULTS: The optimized formulation was composed of microcrystalline cellulose 20%, crosslink polyvinyl pyrrolidone 6%, sodium carboxymethyl starch 5.5% and polyvinyl pyrrolidone 8%. The dispersible tablets was completely disintegrated in 30 seconds, with its dissolution obviously higher than that of common tablets at 15min. CONCLUSIONS: Pefloxaein mesylate dispersible tablets prepared with this formulation process has controllable quality, shorter disintegration duration and better in vitro release rate than the common tablets.
