Online published on 13 March, 2013. Abstract Simple, accurate, economical and reproducible spectrophotometric methods for simultaneous estimation of Rabeprazole and Ondansetron in combined tablet dosage form have been developed. The developed method employs formation and solving of simultaneous equation using two wavelengths 284.4 nm and 302.0 nm for formation of simultaneous equation. This method obeys Beer's law in the employed concentration ranges. Results of analysis were validated statistically and by recovery studies.
