Simultaneous Determination of Valsartan and Hydrochlorothiazide in Tablets by High-Performance Liquid Chromatography

Pages 2491-2500 | Published online: 27 Feb 2008
 

ABSTRACT

A method for the simultaneous determination of valsartan and hydrochlorothiazide in tablets is described. The procedure, based on the use of reversed-phase high-performance liquid chromatography, is linear in the concentration range 5.0-10.0 μg ml−1 for valsartan and 0.5-2.0 μg ml−1 for hydrochlorothiazide, is simple and rapid and allows accurate and precise results. The limit of detection was 1.0 μg ml−1 for valsartan and 0.05 μg ml−1 for hydrochlorothiazide.
