很多药物及制剂,经过长期贮存,仍很安定;但也有一些比较不安定的药物,经贮存后会起一些不同程度的变北。这些变化包括变色、生霉、腐败、变质、潮解、风化、产生沉淀等等。改善贮存的条件或把药物加以适当的处理(如加入防腐剂),往往可以使这些变化减少或完全不致产生。下面介绍较合理的贮存方法。 Many drugs and preparations are still stable after long-term storage; however, there are also some more unstable drugs that will change to some extent after being stored. These changes include discoloration, mildew, spoilage, deterioration, deliquescence, weathering, precipitation, and the like. Improving storage conditions or appropriate treatment of the drug (eg adding preservatives) can often reduce these changes or not at all. The following describes a more reasonable storage method.
