A simple, rapid and precise Reverse Phase High Performance Liquid Chromatography (RP-HPLC) method was developed for simultaneous estimation of paracetamol and pamabrom in bulk and combined pharmaceutical dosage form by using BDS hypersil C18 column. The sample was analysed using phosphate buffer (pH-4): methanol (65:35v/v) as a mobile phase at a flow rate of 1.0 ml/min and detected at 270 nm. The retention time for paracetamol and pamabrom was found to be 4.04 min and 7.36 min respectively. The linearity of developed method was achieved in the range of 32.5-97.5μg/ml for paracetamol and 2.5-7.5μg/ml for pamabrom. The method was validated in terms of accuracy, precision, linearity, limit of detection, limit of quantitation and robustness as per International Conference Harmonization (ICH) guidelines.
