目的:制备司帕沙星眼用凝胶。方法:以卡波姆-940为基质制备司帕沙星眼用凝胶。采用正交设计试验,以样品的黏稠度、透明度及pH为考察指标,优化处方配比。结果:所制制剂为淡黄色胶体,凝胶质量符合《中国药典》2010年版眼用凝胶的质量要求。司帕沙星眼用凝胶中卡波姆-940、甘油和1,2-丙二醇的最佳用量分别为0.4%、10%和6%。结论:司帕沙星眼用凝胶的制备工艺简单、可行。
Objective: To prepare sparfloxacin ophthalmic gel. Methods: Sparfloxacin ophthalmic gel was prepared with carbomer-940 as matrix. Orthogonal design test was used to test the viscosity, transparency and pH of the sample to optimize the prescription ratio. Results: The preparation was light yellow colloid, gel quality in line with the “Chinese Pharmacopoeia” 2010 edition of the quality requirements of eye gel. Sparfar star ophthalmic gel carbomers -940, glycerin and 1,2-propanediol best dosage were 0.4%, 10% and 6%. Conclusion: Sparfloxacin eye gel preparation process is simple and feasible.
