Two simple, sensitive and accurate methods have been developed for the quantitative analysis of cinitapride in its pure and pharmaceutical formulations. The proposed methods were based on formation of a violet coloured complex that has resulted from the reaction of diazotized cinitapride and N-(1-naphthyl)ethylenediamne dihydrochloride (method-I) and the formation of yellow coloured molecular salt complex resulting from the reaction of cinitapride with 2,4,6-trinitrophenol (Method-II). These methods have showed the absorption maximum at 525nm and 410 nm and linearity in the concentration range of 4-24 µg/ml and 8-40 µg/ml for method-I and method-II respectively. The results of analysis for the proposed methods were validated statistically by recovery studies.
