A simple, robust, precise, UV spectroscopic method has been developed for the simultaneous estimation of Nebivolol and Valsartan in bulk and tablet dosage forms. In this paper the estimation of those drugs was carried out by simultaneous equation method. This method is based on measurement of absorption at 281nm and 251nm i.e, λmax of Nebivolol and Valsartan respectively. The linearity observed for Nebivolol is in the range of 5-25 μg/ml and for Valsartan is in the range of 5-80 μg/ml. The accuracy of methods was assessed by recovery studies and was found to be within the range of 99.28%-99.26% for both Nebivolol and Valsartan. The developed methods were validated with respect to linearity, accuracy (recovery), and precision. The method can be employed for estimation of pharmaceutical formulations with no interference from any other excipients and diluents. The results were validated as per ICH guidelines.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
