OBJECTIVE To establish a HPLC method for the determination of Azithromycin and related sub-stances in Azithromycin in situ gelatin for ophthalmic.METHODS The analysis was carried out with Kromasil C8 column (250mm ×4.6mm,5μm),using acetonitrile-phosphate buffer (50:50).The flow rate was 1.0mL? min -1, and detection wavelength was set at 210nm.RESULTS The data showed that this method can clearly separate Az-ithromycin from its nearby impurity,the linear range of Azithromycin was 0.4~1.6mg? mL-1 ,the correlation coeffi-cient was 0.9998 and the average recoveries( n=9) was 99.3%.CONCLUSION The method is simple,specific and accurate,so it can be used for the quality control of this preparation.
