Objective To establish the method for the determination of gatifloxacin in eye gel . Methods The condition of RP‐HPLC was Diamonsil C18 column (250 mm × 4.6 mm ,5 μm) ,mobile phase of acetonitrile‐0.3%phspphoric acid solution adjusted to pH 3 with triethylamine(23∶77) and UV detector at 290 nm . Results The method proved to be linear in the range at 4.0~40.0 μg/ml of gatifloxain with correlation coefficient of 0.9998 . The average recovery and recision were 99.5% ,RSD=1.23% .The precision RSD=2.54% (n=6) . Conclusion The method is simple ,accurate ,specific and can be used to the quality control of the preparation .
