A simple and reproducible method was developed for Paroxetine by Reverse Phase High Performance Liquid Chromatography (RP-HPLC). Paroxetine was separated on ODS column (150 x 4.6 mm, 5μm), using Phosphate buffer: ACN (70:30, v/v), pH-2.6 at the UV detection of 211 nm. Isocratic elution of acetonitrile (ACN) and buffer was used as a mobile phase with various ratios and flow rates, eventually Phosphate buffer: ACN (70:30, v/v), pH-2.6 was being set with the flow rate of 1 mL/min. The statistical validation parameters such as linearity, accuracy, precision, inter-day and intra-day variation were checked, further the limit of detection and limit of quantification of Paroxetine concentrations were found to be 0.006 and 0.19 µg/mL. Recovery and assay studies of Paroxetine were within 98.66 to 99.0 % indicating that the proposed method can be adoptable for quality control analysis of Paroxetine.
