Abstract

A simple, efficient and reproducible reversed phase high performance liquid chromatographic (RP-HPLC) method was developed and validated for the simultaneous estimation of valsartan and hydrochlorothiazide in bulk and in tablets. A column having 250 x 4.6 mm i.d. (Kromasil C18) in isocratic mode with mobile phase containing 50 mM potassium dihydrogen o-phosphate buffer (triethylamine 0.2%), (pH 3.7 adjusted with o-phosphoric acid): acetonitrile (56:44 v/v) was used. The flow rate was 1.0 ml/min and effluent was monitored at 232 nm.  The retention time of valsartan and hydrochlorothiazide was 10.15 and 3.78 min respectively. All calibration curves showed good linear correlation coefficients within the tested limits (r2 > 0.9995). The linearity dynamic range was found to be 20-150 µg/ml and 5-45 µg/ml for valsartan and hydrochlorothiazide respectively. Percentage recoveries for valsartan and Hydrochlorothiazide were 100.45 % and 98.75 % respectively. All the analytical validation parameters were determined and found in the limit as per the International Conference on Harmonization (ICH) guidelines which indicates the validity of the method. The developed method was found to be accurate, precise and robust for the simultaneous estimation of valsartan and hydrochlorothiazide in bulk and in tablets.
