硫酸罗通定是一镇痛药。其注射液的产品使用说明中,只说明遮光、密闭保存,而在前面的说明中又指出遇光或受热颜色加深。查阅相关资料,未见对硫酸罗通定注射液的稳定性及室温贮存期报道。我们采用初均速法对硫酸罗通定注射液的稳定性进行了研究,并对其室温贮存期进行了预测。1 仪器与药品1.1 仪器 岛津uv-210紫外分光光度计(日本岛津公司);HHS212型双列双孔电热恒温水溶锅(山东医疗器械厂)。 Luo Tongding is an ancient painkiller. The injection of the product instructions, only to illustrate shading, airtight preservation, and in the preceding description also pointed out that the case of light or heat color deepen. Access to relevant information, no stability of the injection of Luo Tongding sulfate and room temperature storage period reported. We studied the stability of LuoTuoDing injection by using the average initial velocity method, and predicted its room temperature storage period. 1 Instruments and Pharmaceuticals 1.1 Instrument Shimadzu UV-210 UV spectrophotometer (Japan Shimadzu Corporation); HHS212 double-row double-hole electric heated water bath (Shandong Medical Devices Factory).
