Yang Shu qun 1, He Hai xia 2 and Zhou Yuan da 2 (1 The Second Affiliated Hopsital, Chongqing Medical University, Chongqing 400010; 2 The First Affiliated Hopsital, Chongqing Medical University, Chongqing 400016)  
To study the blood or intraocular distribution and pharmacokinetics of intravenously administered ciprofloxacin in rabbits′ eyes. The blood or intraocular concentrations of ciprofloxacin were measured by high performance liquid chromatography (HPLC). The peak concentrations ( C max ) of ciprofloxacin in lachrymal fluid, cornea, aqueous humor, iris ciliary body, lens, vitreous body were (8.92±2.88), (142.84±25.02), (11.06±2.80), (99.32±10.60), (30.28±1.91) and (8.10±1.71)μg/ml(μg/g) respectively. The half life ( T 1/2β ) of various concentration in blood, lachrymal fluid, cornea, aqueous humor, iris ciliary body, lens and vitreous body was (1.21±0.23), (1.48±0.97), (1.66±0.13), (2.01±0.51), (1.52±0.92), and (1.21±0.66)h, respectively. Results indicate that ciprofloxacin can penetrate various intraocular tissues.
