High-performance liquid chromatographic and UV spectrophotometric methods were developed and validated for the quantitative determination of pirfenidone, a novel antifibrotic agent used in idiopathic pulmonary fibrosis. Chromatography was carried out by isocratic technique on a reversed-phase C18 Zorbax Eclipse plus column with mobile phase consisting of acetonitrile:water (35:65 %v/v) at flow rate of 0.7 ml/min. The UV spectrophotometric determinations were performed at 317 nm using methanol as a solvent. The proposed methods were validated according to International Conference on Harmonization ICH Q2 (R1) guidelines. The linearity range for pirfenidone was 0.2-5.0 and 3-25 μg/ml for HPLC and UV method, respectively. Both the methods were accurate and precise with recoveries in the range of 98 and 102 % and relative standard deviation <2 %. The developed methods were successfully applied for determination of pirfenidone in tablets.
已开发并验证了高效液相色谱法和紫外分光光度法,用于定量测定吡非尼酮,一种用于特发性肺纤维化的新型抗纤维化药物。色谱分析采用等度洗脱技术,在反相C18 Zorbax Eclipse plus柱上进行,流动相为乙腈:水(35:65 %v/v),流速为0.7 ml/min。紫外分光光度法测定在317 nm波长下进行,以甲醇为溶剂。所提出的方法根据国际协调会议ICH Q2 (R1)指南进行了验证。吡非尼酮的线性范围,HPLC法为0.2 - 5.0 μg/ml,紫外法为3 - 25 μg/ml。两种方法均准确、精密,回收率在98%至102%之间,相对标准偏差<2%。所开发的方法成功应用于片剂中吡非尼酮的测定。
