摘　　要：目的采用UV法测定枸橼酸西地那非口崩片的含量均匀度。方法以0.01 mol·L^(-1)盐酸为溶剂,在292 nm处用紫外分光光度计快速测定枸橼酸西地那非口崩片的含量均匀度。结果11.14~39.89μg·mL^(-1)枸橼酸西地那非对照品与吸光度呈良好的线性关系;平均回收率为101.42%,RSD为0.40%;配制的样品溶液在8 h内稳定;3批枸橼酸西地那非口崩片的含量均匀度均在合格范围内,A+2.2S分别为3.54、1.98、2.70,与HPLC法比较无明显差异。结论所用方法操作简便快速、经济、重复性良好,可用于枸橼酸西地那非口崩片含量均匀度的测定。OBJECTIVE To determine the content uniformity of sildenafil citrate orally disintegrating tablets using UV spectrometry.METHODS The homogeneity of the content of sildenafil citrate orally disintegrating tablets was rapidly determined by UV spectrophotometer at the detection wavelength of 292 nm,using 0.01 mol·L^(-1)hydrochloric acid as solvent.RESULTS A good linear relationship was shown between the concentration of sildenafil citrate control and the absorbance in the range of 11.14-39.89μg·mL^(-1).Its average recovery was 101.42%with RSD of 0.40%and the prepared sample solution was stable within 8 h.The content uniformity of the three batches of orally disintegrating tablets of sildenafil citrate was determined to be within the qualified range,with A+2.2S of 3.54,1.98,2.70,respectively.There was no significant difference compared with the HPLC method.CONCLUSION The method is simple,rapid,economical,reproducible and can be used for the determination of the uniformity of the content of sildenafil citrate orally disintegrating tablets.
