Objective To establish a method for the determination of the glibenclamide content in Glibenclamide Sustained Release Pellets CaPsules. Methods HPLC was Performed on the Waters Xterra RP18 column(250 mm × 4. 6 mm, 5μm) with methanol-0. 05 mol/L sodium dihydrogen PhosPhate ( 30:70 ) as the mobile Phase and the flow rate of 1 mL/min. The detection wavelength was at 300 nm. The column temPerature was 35 ℃ and the samPle size was 20 μL. Results The linear range of glibenclamide was 0. 5-3. 0 μg ( r=0. 999 9 ) , the average recovery rate was 99. 95% ,RSD=0. 80% ( n=6 ) . Conclusion This method is simPle, accurate, highly sPecific and can be used for the quality control of this PreParation.
