| Sumario: | Asimple, precise and sensitive reverse-phase high performance liquid chromatographic method was developed and validated for the simultaneous determination of ezetimibe and simvastatin in pharmaceutical formulations. Chromatographic separation was performed on a Merck Cl 8 columnata wavelength of 240 nm using a mixture of 0.1M ammonium acetate buffer pH 5.0 and acetonitrile in the ratio of (30:70, v/v). The method results in excellent separation with good resolution between the two analytes. The within day variation was between 0.28 and 1.10 % and between day variation was between 0.56 and 1.32 %. The recovery was greater than 99.12 % with RSD less than 1.38 %. The method was validated according to ICH guidelines by performing linearity, accuracy, precision, limits of quantitation and selectivity. The results show mat the method is suitable for its intended use |
