A reverse phase high performance liquid chromatographic method was developed for the simultaneous estimation of Ampicillin sodium and Sulbactam sodium in injectable formulation.  The separation was achieved by Inertsil C18 column (250mm × 4.6mm i.d 5µm particle size) and Acetonitrile: Ammonium acetate buffer pH = 6.0 (17 : 83) as mobile phase at a flow rate of 1.0mL/min. The retention times of Ampicillin sodium and Sulbactam sodium were found to be 5.86mins & 4.33mins respectively. The proposed method was validated for linearity, accuracy and precision. The calibration curve was linear over the range of 50-150 µg/mL for Sulbactam sodium and 100 - 300 µg/mL for Ampicillin sodium. The proposed method can be applied successfully in routine analysis.
