OBJECTIVE:To modify the HPLC method for determining the contents of cefpodoxime proxetil and cefpodoxime proxetil capsules or suspension,and to compare it with the method of UV determination.METHODS:Column:ODS-C18,mobile phase:methanol-water(50∶50),flow rate :1.5mL?min-1,column temperature:40℃,detection wavelength:235nm.RESULTS:The standard curve was rectilinear when cefpodoxime proxetil was within the range of 25～150?g?mL-1(r=0.999 9).The average recovery rate was 98.56%(RSD=1.79%)and the average content of the samples was 101.54%.CONCLUSIONS:The method is simple,rapid,accurate and sensitive for determination of cefpodoxime proxetil and cefpodoxime proxetil capsules or suspension.
