Abstract: Simple, inexpensive, rapid and sensitive determination of furosemide spectrofluorometrically was suggested using acriflavine as a new reagent. The method based on the quantitative quenching effect of furosemide on the native fluorescence of acriflavine in presence of Britton-Robinson buffer medium due to the reaction of furosemide with acriflavine to form an ion associated complex. The decrease of acriflavine fluorescence was observed at 505 nm after excitation at 265 nm. the florescence – concentration plot is rectilinear over the range of 2.0-10 µg/ml with correlation coefficient 0.9991 and detection limit 0.2 µg/ml. No interference was observed from the excipients that are commonly present in pharmaceutical formulations. The proposed method was determination of furosemide in some commercial tablets. The results were compared with that of HPLC method revealed with good agreements and no significant differences in the accuracy and precision.
