Two simple, accurate, sensitive, precise and economical spectrophotometric methods have been developed for the determination of amisulpride (AMS) in tablet formulation. The developed methods were based on the formation of a yellow coloured chromogen due to the reaction of amisulpride with methyl orange (method-I) and formation of a blood-red coloured complex resulted from the reaction of amisulpride with 2, 5-dihydroxy, 3, 6-dichloro-1, 4-benzoquinone (method-II). The proposed methods showed the absorption maxima at 420 nm, 545 nm and have good linearity in the concentration range of 5- 25 μg/mL and 50-250 μg/mL for method-I and method-II respectively. The results of analysis for the proposed methods were validated statistically by recovery studies.
