A simple isocratic HPLC method has been developed and subsequently validated for simultaneous determination of Perindopril and Indapamide in pharmaceutical dosage forms. The method employs an Inertsil ODS C18 column, 5 ì, 250 mm x 4.60mm id with flow rate of 1.5 ml/min using UV detection at 215nm. The separation was carried out using a mobile phase consisting of potassium di hydrogen phosphate buffer having pH 5 and acetonitrile in the ratio of 60:40 respectively. The retention time for Perindopril and Indapamide was found to be 2.85 min and 3.85 min respectively. A linear response was observed over the concentration range of 5.0-40.0 µg / ml and 2.5 - 15.0 µg / ml for the assay of Perindopril and Indapamide with correlation coefficient of 0.9992 and 0.9994, respectively. The results of analysis were validated stastically and by recovery studies. Hence the proposed method was found to be accurate, precise, reproducible and specific and can be used for simultaneous analysis of these drugs in tablet formulations.
