ABSTRACT
A simple, accurate and precise spectroscopic method was developed for simultaneous estimation of Itopride Hydrochloride and Lansoprazole in synthetic mixture using first order derivative zero-crossing method. Itopride Hydrochlorideshowed zero crossing point at 278.12nmwhile Lansoprazole showed zero crossing point at 244.58nm. The dA/dλ was measured at 244.12 nm for Itopride Hydrochloride and 278.12nmfor Lansoprazole and calibration curves were plotted as dA/dλ versus concentration, respectively. The method was found to be linear (r2>0.999) in the range of 5-25μg/ml for Itopride Hydrochloride at 244.58nm. The linear correlation was obtained (r2>0.996) in the range of 5-25 μg/ml for Lansoprazole at 278.12 nm. The limit of determination was 0.155μg/ml and 0.059μg/ml forItopride Hydrochloride and Lansoprazole, respectively. The limit of quantification was 0.472μg/ml and 0.179μg/ml for Itopride Hydrochloride and Lansoprazolerespectively. The accuracy of these method were evaluated by recovery studies and good recovery result were obtained greater than 99% shows first order derivation zero crossing. The method was successfully applied for simultaneous determination of Itopride Hydrochloride and Lansoprazolein binary mixture.
