发布时间:2019-01-28 22:23
【摘要】:目的通过考察国内不同药品生产企业头孢氨苄甲氧苄啶胶囊的溶出情况,评价其药品质量,并对溶出度检查方法的合理性进行探讨。方法采用桨法(转速为50r/min),分别以pH1.2盐酸溶液、pH4.0醋酸盐缓冲液、pH6.8磷酸盐缓冲液和水为溶出介质,绘制各企业头孢氨苄甲氧苄啶胶囊中主成分头孢氨苄的溶出曲线。结果 12家企业中仅有5家企业的产品在4种介质中的溶出曲线是相似的,并且与日本橙皮书中收载的头孢氨苄胶囊参比制剂的溶出曲线相似;各企业产品以水为溶出介质的区分度明显好于0.1mol/L盐酸溶液。结论国产头孢氨苄甲氧苄啶胶囊溶出度不同企业间有显著差异;产品质量有待提高;溶出度方法亟待改进。
[Abstract]:Objective to investigate the dissolution of Cefalexin trimethoprim capsules and evaluate the quality of Cefalexyl trimethoprim capsules in different drug manufacturers in China and discuss the reasonableness of dissolution test method. Methods using paddle method (rotational speed 50r/min), pH1.2 hydrochloric acid solution, pH4.0 acetate buffer solution, pH6.8 phosphate buffer solution and water as dissolution medium, respectively. The dissolution curves of cefalexin in cefalexin capsules were drawn. Results the dissolution curves of the products of only 5 out of 12 enterprises were similar to those of the cefalexin capsule reference preparation in Japanese orange peel book. The degree of differentiation of the product with water as dissolution medium is better than that of 0.1mol/L hydrochloric acid solution. Conclusion there are significant differences in dissolution of cefalexin trimethoprim capsules between different enterprises, the product quality needs to be improved, and the dissolution method needs to be improved.
