A new RP-HPLC method has been developed for the simultaneous estimation of nebivolol hydrochloride and hydrochlorothiazide in pharmaceutical dosage forms, using ultra violet (UV) detector. Elution was carried out using a mobile phase consisting of acetonitrile and potassium dihydrogen phosphate buffer (pH 3.2 ± 0.1) in the ratio of 50:50 v/v and flow rate was set on 1.2 ml/min at 282 nm. The retention time for hydrochlorothiazide and nebivolol hydrochloride was found 3.57 and 6.66 mins, respectively. The method was found to be linear in the range of 8-32 mg/ml and 20-80 mg/ml for nebivolol hydrochloride and hydrochlorothiazide, respectively. In the linearity study, regression equation and coefficient of correlation for nebivolol hydrochloride and hydrochlorothiazide were found to be: y = 284761x + 215452, r = 0.9995; and y = 698395+105272, r = 0.9998, respectively. |
