理由是完全不成立的
学过化学的人都应该知道
化学反应的程度与温度是呈正相关的
换句话说
低温只能使样品更稳定
除非是有相变发生不好说
国内没有相关的贮存说明
但这是常识问题
另外做过稳定性试验的人都知道
样品在取出后不能即时检验的都应该放到低温下保存
再给你找一下USP的要求
在USP凡例中关于受控室温是这样规定的
10.30.60. Controlled Room Temperature
“Controlled room temperature” indicates a temperature maintained thermostatically that encompasses the usual and customary working environment of 20 to 25 (68 to 77F); that results in a mean kinetic temperature calculated to be not more than 25; and that allows for excursions between 15 and 30 (59 and 86F) that are experienced in pharmacies, hospitals, and warehouses. Provided the mean kinetic temperature remains in the allowed range, transient spikes up to 40 are permitted as long as they do not exceed 24 hours. Spikes above 40 may be permitted if the manufacturer so instructs. Articles may be labeled for storage at “controlled room temperature” or at “up to 25”, or other wording based on the same mean kinetic temperature. The mean kinetic temperature is a calculated value that may be used as an isothermal storage temperature that simulates the nonisothermal effects of storage temperature variations. (See also Pharmaceutical Stability 1150.)
An article for which storage at controlled room temperature is directed may, alternatively, be stored and distributed in a cool place, unless otherwise specified in the individual monograph or on the label.
基本意识是对超过温度上限是有明确要求的
即不超过40度且连续24小时平均动力学温度不超过25度
甚至受控室温也可以描述成不超过25度
最后一段最关键
就是明确说明
如果没有特殊规定
规定受控室温的产品在贮存和发运中也可以在COOL条件下
而COOL在USP中规定为8-15度
也可以在冰箱中 |
