药品质量保证是安全用药的前提[1],药品的质量稳定与否,除取决于药物理化性质和包装材料等因素外,贮藏环境是决定性的因素[2]。药品在贮藏过程中的质量稳定与否,除取决于药品本身的结构、理化和生物特性以及工艺技术、包装容器等条件外,在很大程度上还受到贮藏条件的影响,如温度、湿度、光线等,受热或温度过低等不良情况往往会使药品发生分解、挥发、沉淀、酸败、生霉、冻结、冻裂、分层、结晶等变化[3]。
Drug quality assurance is the premise of safe medication [1], the quality of the drug is stable or not, except depending on the physical and chemical properties of the drug and packaging materials and other factors, the storage environment is the decisive factor [2]. In addition to depending on the structure, physicochemical and biological properties of the drug itself, as well as the process technology and the packaging container, the quality of the drug during storage is largely affected by the storage conditions such as temperature, humidity, Light, heat and temperature is too low and other adverse conditions often make the drug decomposition, volatilization, precipitation, rancidity, mold, freezing, cracking, delamination, crystallization and other changes [3].
