A simple, accurate and precise stability-indicating RP-HPLC method was developed and subsequently validated for simultaneous determination of ilaprazole and domperidone in bulk and pharmaceutical dosage form. The proposed HPLC method utilizes  C18  (250 mm × 4.6 mm × 5 µm) column with mobile phase comprising of 0.5 % glacial acetic acid in water pH 5.5 adjusted with ammonia solution: methanol in the ratio 45:55 v/v at a flow rate of 1.0 ml/min. Quantitation was achieved with UV detection at 286 nm based on peak area with linear calibration curves at concentration  ranges 80-120µg/ml for ilaprazole and 240-360 µg/ml for domperidone  with correlation coefficient of 0.999.The retention times of ilaprazole and domperidone  were found to be 3.0 min, 5.4 min respectively. The mean recoveries obtained for ilaprazole and domperidone were found to be 99.76 ± 0.6463 % and 100.7 ± 0.2424 % respectively. Stress testing which covered acid, alkali hydrolysis, and peroxide, photolytic, thermal degradation was performed to prove the specificity of the proposed method and degradation was achieved. The proposed method was successfully applied for the stability indicating simultaneous estimation of ilaprazole and domperidone in routine quality control analysis in bulk and pharmaceutical formulation.
