Abstract

Simple, easy, and economical UV spectrophotometric methods have been developed using simulated tear fluid (STF) solvent to determine levofloxacin hemihydrate (LEVH) levels in ocular nanoparticles, as indicated by the % entrapment efficiency. A maximum wavelength of levofloxacin at 288nm, with a 4.0-12.0µg/mL concentration, shows linear results with a correlation coefficient (r) of 0.9997 and an average % recovery of 99.920 –100.804%. The developed method is able to use for the analysis of levofloxacin hemihydrate in nanoparticle preparations.
