ABSTRACT Objective: To prepare ciclopirox olamine film and determine the content by HPLC.Method: Hypersil ODS C18column(250 mm×4.6 mm,5 μm)was used,the mobile phase consisted of 0.02 mol•L-1 sodium dihydrogen phosphate solutionmethanol(40∶60),the flow rate was 1.0 ml•min-1,the detection wavelength was at 304 nm,and the column temperature was 30 ℃.Result: The method can completely separate Ciclopirox Olamine and its related substances in Ciclopirox Olamine film,and showed good linearity for Ciclopirox Olamine whthin the range of 32-192 μg•ml-1(r=0.999 6),and the average recovery was 100.5%(RSD=0.9%).Conclusion: The preparation is simple, and the method is accurate and reliable.
