RP-HPLC Method Development and Validation of Indapamide And Perindopril In Pharmaceutical Dosage Forms

A simple, precise and rapid HPLC method has been developed for the simultaneous determination of Indapamide and Perindopril in pharmaceutical dosage form. The method was carried out using Hypersil BDS C18 column (250 mm x 4.6 mm, 5µm) and mobile phase of phosphate buffer pH 3.5±0.05 and methanol in the ratio of 65:35 v/v and degassed under ultrasonication. The flow rate was 1.0 mL/min and the effluent was monitored at 215 nm. The retention times of Perindopril and Indapamide were 3.53 min and 4.09 min respectively. The method was validated. Linearity was in the range of 160 to 480 µg/mL for Perindopril and 50 to 150 µg/mL for Indapamide respectively. The percentage recoveries of both the drugs were ranging from 97.8 to 101.7 for Perindopril and 98.7 to 101.8 for Indapamide respectively from the tablet formulation. The proposed method is suitable for the routine quality control analysis of simultaneous determination of Perindopril and Indapamide in pharmaceutical dosage form.
