%X Omeprazole is a potent proton pump inhibitor for the treatment of various acid-related gastrointestinal disorders. simple, selective and rapid reversed phase high performance liquid chromatographic (RP-HPLC) method for the analysis of Omeprazole has been developed and validated. The separation was achieved from HPLC column (ZORBAX, XDB, C-18 (150กม4.6 mm, 5 micron) with a mobile phase consisting of HPLC grade acetonitrile and phosphate buffer solution (pH 7.4) in the ratio of (60:40 v/v) at a flow rate of 0.5 ml/min and runtime 10 min with UV detector at 302nm. The method was specific and it was observed that no interference with diluents. The proposed method was accurate with 100.95% recovery omeprazole and precise (% RSD of area of system precision, % RSD of assay of method precision were found to be 0.14% and 0.37% respectively). From the linearity study the correlation coefficient is found to be 0.9988, which indicated that the method was linear over 25% to 175% range. The method was found robust for possible changes. Therefore, this method can be used as a more convenient and efficient option for the analysis of Omeprazole to establish the quality of the drug substance during routine analysis with consistent and reproducible results
