Abstract

A reverse phase liquid chromatography method (RP-HPLC) was developed to estimate the amount of Piribedil and Indapamide in bulk and its pharmaceutical formulations. Agilent HPLC system equipped with auto sampler, UV-Visible detector Nucleosil 5 C18, 15 cm X 4.6 mm, 5 µm was used for chromatographic separation by using at a detection wavelength of 233 nm was used. Keeping the flow rate of 1.3 mL/min the composition of mobile phase water: acetonitrile: methanol: trifluro acetic acid (80:18:02:0.2) mL/v: v: v: v in given amount were used for the quantification of the drugs. The objective of this study was to developed and validated for the routine analysis of Piribedil and Indapamide in API and tablet dosage forms. The developed method was validated according to the ICH guidelines. The linearity, precision, range, and robustness were within the limits as specified by the ICH guidelines. Hence, the method was found to be simple, accurate, precise, economic, and reproducible
