Abstract

 A simple, sensitive and rapid spectrofluorimetric method was developed and validated for the determination of Gemifloxacin mesylate (GFX), in bulk powder, pharmaceutical preparations and biological fluids. The proposed method was based on complexation of GFX with AlCl3 as complexing agent then measuring the fluorescence of the resulted complex after enhancement with sodium dodecyl sulphate (SDS) in borate buffer (pH 8) at emission wavelength of 401 nm after excitation at 264 nm. Different experimental parameters affecting the fluorescence intensity were carefully studied and optimized to obtain the maximum fluorescence intensity. The developed method was validated according to International Conference on Harmonisation guidelines in terms of specificity, linearity, lower limit of quantification (LOQ) 0.54 ng.ml-1, lower limit of detection (LOD) 0.18 ng.ml-1, accuracy and precision. The proposed method was found to be rectilinear over the concentration range of 1-20 ng.ml-1with recovery percentage of 99.85±0.84. The proposed method was applied successfully for the determination of GFX in pharmaceutical preparations and spiked human plasma with recovery percentage of 99.97±0.79 and 99.96±1.73 respectively. The results were statistically analyzed and compared with a reference method and no significance difference was found between both methods.
