麦角流浸膏为产科常用的药物,但因性质很不稳定,易于失效变质,制备后贮放不久含量即显著降低。为了解决这一问题,作者等对麦角流浸膏的稳定剂进行了研究。据文献记载,麦角生物硷很不稳定,光綫、氧、湿气及稍高的温度都能使其变质。为了使其制剂稳定,通常加入各种抗氧剂、防腐剂及充填氮气或二氧化碳等作为稳定剂。考虑到麦角流浸膏的包装名为500毫升. Ergot flow extract for the obstetrics and gynecology commonly used drugs, but because of the nature of instability, easy to degenerate, shortly after storage content is significantly reduced. In order to solve this problem, the authors studied the stabilizer of ergot extract. According to the literature, ergot alkaloids are very unstable, light, oxygen, moisture and slightly higher temperature can make it metamorphic. In order to stabilize the formulation, various antioxidants, preservatives, and nitrogen or carbon dioxide are usually added as stabilizers. Taking into account the ergot flow extract packaging name is 500 ml.
