Ezetimide belongs to a class of lipid lowering    compounds    that    selectively    inhibits intestinal   absorption   of   cholesterol   and   related phytosterols. The purpose of this study is to establish a reliable and quick method for the assignment of ezetimibe in tablets form by high performance liquid chromatography with ultraviolet detection (HPLC-UV). A rapid  and  sensitive  HPLC  method  has  been developed  for  determination  of  ezetimibe in tablets formulation.  Mobile phase was composed of acetonitrile-ammonium acetate (10 mM, pH 3.0), 75:25 (v/v) with a flow rate of 1 ml/min. The eluted peaks were detected by a UV detector was set at wavelength of 240 nm. The method results in excellent separation with good resolution of analyte. Standard curves were linear (r = 0.996) over the wide ezetimibe concentration range of 10-60.0 µg mL-1 with acceptable accuracy and precision. The limits of detection (LOD) and quantitation (LOQ) of the method were 5 and 10 µg/ml, respectively. The average drug recovery was 95.3% throughout the linear concentration range. Statistical  assessment  of  various  in  vitro  dissolution  parameters  and  assay  results was  also  conducted  to  establish  if  there were  any significant difference among them. The validated HPLC method has been used successfully to study ezetimibe. Due to simplicity, rapidity and accuracy of the method, we believe that the method will be useful for routine quality control analysis.
