Abstract

Literature survey reveals that few spectrophotometric, high performance liquid chromatographic (HPLC)and High performance thin layer chromatographic (HPTLC)methods were reported for the estimation of Amlodipine and perindopril in bulk and combined pharmaceutical dosage forms. But there is no any stability indicating high performance liquid chromatography study is reported for amlodipine. So the present study was aimed to development of simple, accurate, rapid and economical HPLC stability indicating assay method were established for the determination of Amlodipine and Peridopril in bulk and tablet dosage form. A High-performance liquid chromatograph WATERS, software: Empower 2,2695 separation module, 996 PDA detector, using Phenomenex Luna C18 (4.6mm×250mm) 5µm or equivalent column, with mobile phase composition of Methanol: Phosphate Buffer pH3.0 (70:30v/v) was used. The flow rate of 1.0ml min-1 and effluent was detected at 230nm. The retention time of Amlodipine and Perindopril was found to be 1.870min and 2.499minutes respectively. Linearity was observed over concentration range of 10-50µg ml-1 for Amlodipine and 16-80µg ml-1 for Perindopril respectively. The accuracy of the proposed method was determined by recovery studies and the Amlodipine was found to be 99.1% and Perindopril was found to be 98.8% respectively. The proposed method is applicable to routine analysis of Amlodipine and Perindopril in bulk and pharmaceutical formulations. The proposed method was validated for various ICH parameters like linearity, limit of detection, limits of quantification, accuracy, precision, range and specificity.
