Development and Validation of Spectrophotometric Methods for Simultaneous Estimation of Naproxen and Esomeprazole Magnesiumtrihydrate in Combined Pharmaceutical Formulation

Abstract

Four simple, rapid, precise and accurate spectrophotometric methods have been developed for simultaneous analysis of Naproxen (NAP) and Esomeprazole Magnesiumtrihydrate (ESO) in their combined dosage form. Method A, zero crossing first derivative spectrophotometry involves measurement of amplitudes at 276.4 nm (for NAP) and 322.2 nm (for ESO) in first… (More)
