The present work describes a simple reverse phase HPLC method for the determination of omeprazole and domperidone from tablet formulations. The determination was carried out on a Hypersil, ODS, C-18 (150×4.6 mm, 5 micron) column using a mobile phase of methanol:0.1 M ammonium acetate (pH 4.9) (60:40). The flow rate and runtime were 1 ml/min and 10 min, respectively. The eluent was monitored at 280 nm. The method was reproducible, with good resolution between omeprazole and domperidone. The detector response was found to be linear in the concentration range of 10-60 µg/ml for omeprazole and 5-30 µg/ml for domperidone.
