克拉霉素分散片的处方工艺改进

Improvement of the Formulation of Clarithromycin Dispersible Tablets

目的 :研究制备克拉霉素分散片的最佳处方工艺 ,以解决原处方生产的片剂易缺角、烂边的问题。方法 :内加低取代羟丙基纤维素 (LS -HPC) ,通过处方筛选以确定制备处方工艺。结果 :用LS -HPC取代原处方的淀粉较为理想 ,增加了片剂的硬度 ,改善了脆碎度 ,解决了原片剂的缺角、烂边问题。结论

OBJECTIVE:To obtain an optimum formulation of clarithromycin dispersible tablets METHODS:The preparation process was set by way of screening formulation and a formula with substitution of LS-HPC for starch was adopted RESULTS:The results showed that the substitution of LS-HPC for starch was the most preferable formulation The hardness and the friability of the tablets were improved The external apperance of unfilled corner and torn edge of the unimproved tablets was resolved CONCLUSION:Modified formulation is favorable for improving the quality of the product
