Three simple, accurate, sensitive, precise and economical spectrophotometric methods have been developed for the determination of prulifloxacin in tablet formulation. The developed methods were based on the formation of a blue coloured chromogen due to the reaction of prulifloxacin with Folin-ciocalteu reagent in presence of sodium carbonate (Method-I), formation of a blood-red coloured complex resulting from the reaction of prulifloxacin in acetonitrile with ortho-phenanthroline (Method-II) and formation of blood-red coloured complex resulting from the reaction of prulifloxacin in acetonitrile with 2, 2’- bipyridyl (Method-III). The proposed methods showed the absorption maxima at 650 nm, 510 nm and 520nm and have good linearity in the concentration range of 50-250 µg/mL, 5-25 µg/mL and 4-20 µg/mL for method-I, method-II and method-III, respectively. The results of analysis for the proposed methods were validated statistically by recovery studies.
