Development and Validation of Spectrophotometric and Chromatographic Analytical Methods of Triamterene and Hydrochlorothiazide in Dosage Form
Authors
Abstract
The UV and RP-HPLC method describes developed simple, rapid, specific, selective, accurate and precise method for the simultaneous estimation of triamterene and hydrochlorothiazide in dosage form. Hydrochlorothiazide diuretic agents whereas triamterene RP-HPLC method for triamterene and hydrochlorothiazide were developed using mobile phase Phosphate Buffer: Acetonitrile (70:30), flow rate 1 ml/min, injection volume 20μL, temperature 25ºC detection wavelength 222nm. Linearity range was found to be 0.66-29.8μg/ml for triamterene and 0.60-18.2μg/ml for triamterene. LOD and LOQ values were found to be 0.127 and 0.390 μg/ml for triamterene and 0.144 and 0.434 μg/ml for hydrochlorothiazide respectively. The assay result found to be 99.75% and 99.97% for triamterene and hydrochlorothiazide respectively. The developed method was validated according to ICH guidelines.
