Assigned to Shenyang Xingqi Pharmaceutical Co Ltd · Expires 2023-09-05 · 3y expired

What this patent protects

本发明涉及提高妥布霉素滴眼液稳定性的包装容器。由于现有妥布霉素滴眼液在稳定性考察期间容易发生氧化降解,以及药液颜色发生变化,存在质量不稳定的缺陷,因而提供了一种新的稳定妥布霉素滴眼液的方法,即通过在妥布霉素滴眼液的包装容器的容器材料中添加特定抗氧剂以及含有特定钛白粉的色母,使得妥布霉素滴眼液在稳定性考察期间通过氧化途径降解的杂质减少,且药液颜色未发生变化,提高了产品质量,从而确保了其临床疗效。
