Objective:To establish an RP-HPLC method for determining the dissolution of roflumilast tablets. Methods:Stationary phase was C18 (150mm×4.6mm,5.0μm),with water-acetonitrile (35:65) as the mobile phase. The detection wavelength was 215nm, column temperature was 25℃, and flow rate was 1.0ml/min. Results:The regression equation of roflumilast was A=425705C-273.88,r=0.9999, which was linear over the range of 0.0506~0.9104μg/ml. The average recovery of Dual acylate was 99.77%, and RSD was 0.25%. Conclusion:This method is simple, accurate , repeatable and can be used for the dissolution of roflumilast tablets.
