Objective To establish an RE-HPLC method for the determination of ezetimibe and its related substances in ezetimibe tablets. Methods The analysis was performed on a Cl8 column(150mm×4.6mm, 5μm). The mobile phase consisted of potassium dihydrogen phosphate 0.05mol/L:acetonitrile:tetrahydrof uran=65∶25∶10. The flow rate was 1.0mL?min-1 and the column temperature maintained at 30℃. The detective wavelength was 232 nm. Results Ezetimibe and its related substances were well-separated by this method, and the linear range of ezetimibe was 98.6~295.9μg/ml, r=0.9999. The average recovery of ezetimibe was 100.3% with the RSD was 0.72% (n=9). Conclusion This method is simple, sensitive and accurate,which can be used for the quality control in ezetimbie tablets.
