Abstract: A rapid high performance liquid chromatographic method has been developed and validated for the estimation of atenolol and Hydrochlorothiazide simultaneously in combined dosage form. A RP stainless steel ODS C-18 column having dimensions of 4.6×250 mm and particle size of 5 μm in isocratic mode, with mobile phase containing a mixture of phosphate buffer (0.03 M), pH 3.5 adjusted with orthophosphoric acid and acetonitrile: in the proportion (50:50 v/v) .The mobile phase was pumped at a flow rate of 1.0 ml/min and the eluent were monitored at 226 nm. The developed method was validated with respect to linearity, accuracy, recovery, precision and solution stability studies prove the stability indicating stability of the method.
