ABSTRACT

Objective:To compare the ocular tissue concentrations and pharmacokinetic parameters in rabbit's eyes after topically and subconjunctivally administrated with levofloxacin (LVFX).Methods:The concentrations of LVFX in the cornea,aqueous humor,iris-ciliary body,lens and vitreous at different times were measured by high performance liquid chromatography after 0.3% LVFX were topically and subconjunctivally administrated into rabbits.Results:The penetration of LVFX into the cornea,iris-ciliary body,lens and vitreous after subconjunctival injection was significantly higher than that of topically applied one( P
