Abstract
Aim: The present work focused on the development of sustained-release microsphere formulation of cefixime to provide reduction in dosing frequency, improved antibacterial activity and patient compliance. Methodology & results: Microspheres were prepared by modified emulsion solvent evaporation method and evaluated by in vitro and in vivo studies. Optimized formulation (FK-07) was found to have entrapment efficiency of 81.12 ± 0.93% and particle size of 166.82 ± 0.86 μm. FK-07 sustained release up to 24 h as demonstrated by in vitro drug release and in vivo pharmacokinetic study in rats. FK-07 showed approximately twofold increase in bioavailability and twofold decrease in MIC90 value against Escherichia coli, Klebsiella pneumoniae and Salmonella typhi in comparison to marketed formulation. Conclusion: Sustaining the release of cefixime using microspheres enhanced its bioavailability, antibacterial efficacy and will help in reducing its dosing frequency.
