A simple, accurate, precise and specific RP-HPLC method has been developed for the simultaneous estimation of Aceclofenac and Esomeprazole Sodium in bulk. Chromatographic analysis was carried out on C18 column ( 250mm × 4.6mm, 5µm). Mobile phase used is a homogenous mixture of ACN: Methanol in the ratio of 50:50 v/v. The detection was carried out at 285nm. The retention times were found to be 3.00 and 4.41 min for Aceclofenac and Esomeprazole Na respectively. Both the drugs showed linearity in the range of 30 – 70mcg/ml. The correlation coefficient was found to be 0.99 and 0.992 for Aceclofenac and Esomeprazole Na respectively. The developed method was validated as per ICH guidelines.
