A new simple, sensitive and precise visible spectrophotometric method has been developed for the determination of Secnidazole in bulk and in pharmaceutical formulation. This method is based on the reduction of secnidazole, in the presence of 4N Hydrochloric acid and ethanol to form yellow colored chromogen. Which was estimated at an absorption maximum of 477.5 nm. This method has the linearity in the concentration range of 100-500μg/ml. This method is statistically evaluated for efficacy.Keywords

Two simple, rapid, accurate and price spectrophotometric methods have been developed for simultaneous eatimation of cefixime and ofloxacin in bulk and in tablet dosage form. Method A involves simultaneous equations at 290.4 nm ((λmax of Cefixime) and 297.4nm (λmax of Ofloxacin). Method B involves Absorbance ratio method at 282.0 nm (iso-absorptive point) and 297.4 nm (λmax of Ofloxacin) using ethanol as a solvent.The linearity was observed in the concentration range of 5-25 μg/ml for Cefixime and 2-10 μg/ml for Ofloxacin.The results of analysis have been validated statically and by recover studies and were found satisfactory.Keywords
