摘 要:目的:制备维生素C阴道缓释片,并全面考察其质量。方法:以羟丙甲纤维素为缓释材料制备维生素C阴道缓释片,采用紫外分光光度法测定其释放度,高效液相色谱法测定其有关物质和含量,并对其稳定性和局部刺激性进行考察。结果:样品在0.5,1,2 h的释放量分别为标示量的45%-75%,75%-90%,90%以上。高效液相色谱法测定维生素C的平均回收率为99.8%,RSD为0.78%。在各种试验条件下样品的性质稳定。局部无刺激性。结论:该处方工艺合理,质量可控,所得产品质量稳定,局部使用安全性良好。Objective:To prepare vitamin C vaginal sustained-release tablets and to investigatetheir quality overall. Methods:Vitamin C vaginal sustained-release tablets were prepared with hypromellose used as sustained-release material, and the release rate was determined by ultraviolet-visible spectroophotometry. The related materials and the content were determined by HPLC. Results:The release degrees of prepared tablets were 45% -75% ,75% -90% , and above 90% , respectively, during 0.5,1, 2 h. The average recovery and RSD of HPLC were 99.8% and 0.78%. The prepared tablets showed good stability under various experimental conditions. Conclusion :The design of formula and preparation technique are reasonable, and the quality is stable. It is safe for local use.
