对环孢素Ａ 微乳浓缩液的处方和制备工艺进行了研究。采用ＨＰＬＣ法测定制剂中环孢素Ａ的含量，用毛细管柱ＧＣ法测定制剂中乙醇的含量，并进行了溶液颜色和澄清度的检查。结果表明，本研究研制的微乳浓缩液质量稳定，制备工艺简单，适于开发应用。
The formulation and preparation of cyclosporin A microemulsion concentrates were studied. The content of cyclosporin A in the preparation was determined by HPLC method. The content of ethanol in the preparation was determined by capillary column GC method. The color and clarity of the solution were also examined. The results showed that the microemulsion concentrates developed in this study are of stable quality, simple preparation process and suitable for development and application.
