ABSTRACT
OBJECTIVE:
To develop a HPLC method for simultaneous determinatio n of ofloxacin and dexamethasone ac?etate in compound ofloxacin ear drops.METHODS:
The analysis was carried on a XDB-C 8 ,the mobile phase was composed of methanol-potassium dihydrogen phosphate(0.02mol/L)by gradient elution,the flow rate was1.0ml/min,the column tem?perature was30℃and the detection wavelength was at240nm.RESULTS:
The detectable concentrations of ofloxacin and dexamethasone acetate showed good linear correlation in the ranges of100~500?g/ml and10~30?g/ml respectively,the av?erage recoveries of ofloxacin and dexamethasone acetate were100.6%(RSD=0.46%,n=9)and101.3%(RSD=0.72%,n=9)respectively.CONCLUSION:
The method is accurate and reproducible and can be used for determination of ofloxacin and dexamethasone acetate in compound ofloxacin ear drops.
