Analytical Performance of an HPLC and CZE Methods for the Analysis and Separation of Perindopril Erbumine and Indapamide

DOI: 10.1515/amma-2015-0073

Introduction: Perindopril, as an angiotensin converting enzyme inhibitor and indapamide, as a thiazide like diuretic, can be administrated together for the treatment of high blood preasure and other cardiovascular diseases. The aim of this study was to develop two simple and reliable separation methods for perindopril and indapamide by high performance liquid chromatography and capillary zone electrophoresis in order to evaluate their behaviour under separation conditions, for simultaneous separation.
Materials and methods: Standard solutions of perindopril erbumine and indapamide in proper solvents were analized. An Agilent 1100 series HPLC system was used for the separation of the two analytes on a C18 stationary phase (Zorbax Stable Bond 3.5 µm), under an isocratic elution. As a comparative method, an Agilent 7100 series capillary electrophoresis system was used for the development of the electrophoretic method.
Results: Both developed methods turned to comply to the separation performance parameters such as resolution and selectivity, with low limits of detection, wide range of liniarity. No statistical difference concerning precision of the qualitative parameters was observed. Time analysis less than 5 minutes both for chromatographic and electrophoretic separations proved to generate cost and time effective analysis methods.
Conclusions: Two analytical methods, HPLC and CZE respectively, for the separation of perindoprile erbumine and indapamide have been successfully developed, both recording satisfactory analytical parameters.
