ABSTRACT
A new sensitive, simple, rapid and precise spectrophotometric method has been developed for simultaneous estimation of perindopril and indapamide in pharmaceutical dosage form. This method was based on UV-spectrophotometric determination of two drugs, using simultaneous equation method. It involves measurement of absorbances at two wavelengths 210.4nm (λmax of perindopril) and 241.2nm (λmax of indapamide) in methanol. The linearity was observed in the concentration range of 24 – 56 μg mL-1 for perindopril and 7.5 – 17.5 μg mL-1 for indapamide. The accuracy and precision of the method was determined and validated stastically. The method showed good reproducibility and recovery with % RSD less than 2. Method was found to be rapid, specific, precise and accurate, can be successfully applied for the routine analysis of perindopril and indapamide in bulk, and combined dosage form without any interference by the excipients. The method was validated according to ICH guidelines.
