硝酸舍他康唑泡腾胶囊的制备工艺和含量测定

Preparation and assaying of sertaconazole nitrate effervescent capsules

目的研究硝酸舍他康唑泡腾胶囊的制备工艺及含量测定。方法确定处方的组成，制备泡腾胶囊，并用紫外分光光度法测定硝酸舍他康唑的含量。结果紫外分光光度法测定硝酸舍他康唑含量的标准曲线为A=0．0075p＋0．0096（r=0．9997），在质量浓度10～90mg·L^-1内吸光度与质量浓度之间的线性关系良好。结论该泡腾胶囊的制备方法简单，用紫外分光光度法测定含量，方法可靠。

AIM To study the preparation and assaying method of sertaconazole nitrate effervescent capsules. METHODS The sertaconazole nitrate effervescent capsules were prepared and the assaying method with ultraviolet spectrophotometry was established after the formulation was eonfimed. RESULTS The standard curve of sertaconazole nitrate was A = 0.007 5p ＋ 0.009 6,with a good linearity（ r = 0.999 7） in the range of 10 - 90 mg·L^-1. CONCLUSION The preparation method is simple and the assaying method with ultraviolent spectrophotometry is reliable.
