Abstract

The present study deals with a rapid, simple, accurate, and rugged UV spectrophotometric methods have been developed for the estimation of some water insoluble calcium channel blockers using hydrotropic solubilization phenomenon in pure and as well as in dosage forms. The calibration graphs were linear in the 2-20μg/ml concentration range (r>0.999) for Nimodipine. The detection was made on 346nm & 357nm in methanol or 1% urea. The method was validated according to ICH guidelines by performing linearity, accuracy, precision, limits of quantitation and selectivity. The results show the method is suitable for its intended use.

Keywords: Nimodipine, method validation, simultaneous spectrometric analysis.
