双氯灭痛为非甾体强效消炎镇痛药,在抗风湿药中居于领先地位,双氯灭痛含量测定方法,通常采用紫外分光光度法,所用的溶剂大部分是乙醇,但本制剂的辅料在乙醇中溶解,并在双氯灭痛最大吸收处有吸收,因此,我们改用水为溶剂,消除了辅料的干扰操作简便,回收率也高,结果满意。 Diclofenac is a non-steroidal potent anti-inflammatory analgesic and is leading in anti-rheumatic drugs. The determination of diclofenac content is usually done by UV spectrophotometry. Most of the solvents used are ethanol, but the excipients of this preparation are dissolved in ethanol , And absorption in the maximum absorption of diclofenac, therefore, we use water as the solvent, eliminating the interference of excipient easy to operate, the recovery rate is also high, the results are satisfactory.
