Objective: The aim of this study was to prepare solid lipid microparticles (SLM) with incorporated ofloxacin, suitable for oral delivery.
Methods: Ofloxacin-loaded SLM were prepared using stearic acid and chloroform as lipid matrix and Tween-80 as surfactant, by high shear homogenization technique and followed by lyophilization. The physiochemical characterization of SLMs were investigated by scanning electron microscopy, transmission electron microscopy, zeta potential, zone of inhibition, in-vitro study, ex-vivo study and stability study.
Results: The result demonstrated that the entrapment efficiency, particle size and zeta potential of microparticles were 86.02%, 203.7nm and -32.68mv, respectively. The in-vitro and ex-vivo studies showed sustained release of drug from formulation.
Conclusion: These results indicate that SLM might be a promising delivery system to enhance the pharmacological activity of ofloxacin.
