摘要
目的:制备注射用甲泼尼龙琥珀酸钠,对其进行质量研究,并考察其稳定性。方法:通过溶液稳定性考察、辅料筛选及不同p H值的考察,确定注射用甲泼尼龙琥珀酸钠的处方组成和制备工艺;采用高效液相色谱法测定其含量及有关物质,并对制剂进行了加速和长期条件稳定性考察。结果:制备条件以15℃为宜,处方中选用乳糖为赋形剂,其与主药用量比为25∶40,中间体溶液的p H以7~8为宜;甲泼尼龙琥珀酸钠进样量线性范围为0.01002~5.00800 mg·m L-1(r=0.9999,n=7);低、中、高浓度平均回收率为99.26%、99.24%、99.15%,RSD分别为0.30%、0.20%、0.34%。稳定性考察期内各指标未见明显变化。结论:该制剂处方工艺可行,质量可控,稳定性较好。
Objective: To prepare methylprednisolone sodium succinate for injection, study the quality and investigate its stability. Methods: The preparation technology and formulation of methylprednisolone sodium succinate for injection were confirmed by solution stability study, excipients and p H value selection. The contents and related substance of methylprednisolone sodium succinate were determined by HPLC. Meanwhile, the stability of accelerated test and long-term sample observation test were investigated. Results: The preparation temperature was maintained within 15℃, and lactose was used as excipient, ratio of which to main component was 25 : 40. p H value of intermediate solution was 7~8. The linear range of methylprednisolone sodium succinate was 0.01002~5.008μg(r=0.9999,n=7). The average recovery rates of low,medium,high concentration were 99.26%, 99.24% and 99.15%, RSD were 0.30%, 0.20% and 0.34%, respectively. No obvious changes were observed in each index of stability test. Conclusion: The preparation is feasible in technology, controllable and stable in quality.
