摘要
目的探讨人眼分别滴用0.5%左氧氟沙星、0.3%加替沙星及0.3%乳酸左氧氟沙星后房水中药物浓度差异。方法采用随机、双盲、平行研究方法。选取2006年8月至2007年2月在浙江大学医学院附属第二医院眼科中心预行白内障超声乳化术的老年白内障患者150例(150只单侧眼),使用随机数字表法分为3个大组:0.5%左氧氟沙星组(50只眼)、0.3%加替沙星组(50只眼)、0.3%乳酸左氧氟沙星组(50只眼),每个大组再使用随机排列表分为5个亚组,每个亚组10只眼。按不同大组,术前分别局部给予0.5%左氧氟沙星、0.3%加替沙星或0.3%乳酸左氧氟沙星滴眼,总共4次,每次间隔15min。手术时按不同亚组,分别于最后1次给药后15、30、60、120、180min时抽取房水多于100μl,然后用加样器准确定量至100μl置于带塞试管中。全部标本采用高效液相色谱法测定房水中药物浓度。采用单因素方差分析(ANOVA)对不同时间点的3种药物浓度进行统计学分析,两两之间差异比较采用t检验进行分析。结果给药后15、30、60、120、180min房水内0.5%左氧氟沙星浓度(1.61±0.48)、(2.41±0.80)、(2.93±0.50)、(2.56±0.63)、(1.87±0.88)mg/L分别高于对应时间点的0.3%加替沙星浓度(0.70±0.18)、(1.29±0.54)、(1.59±0.67)、(1.41±0.50)、(1.13±0.28)mg/L及0.3%乳酸左氧氟沙星浓度(0.55±0.39)、(1.15±0.42)、(1.38±0.49)、(1.02±0.33)、(0.55±0.31)mg/L,差异均有统计学意义(F=23.64,12.82,21.13,25.00,12.22;P均〈0.05)。0.3%加替沙星和0.3%乳酸左氧氟沙星的房水药物浓度经检验在15、30、60、120min无明显差异(t=1.09,0.68,0.83,2.00;均P〉0.05)。在180min时0.3%加替沙星的房水药物浓度高于0.3�
Objective To compare the aqueous humor concentration of levofloxacin 0. 5%, gatifloxacin 0. 3% and levofloxacin 0. 3% ophthalmic solution after topical dosing in human eyes. Methods A randomized, double-blind and parallel study was conducted. Senile cataract patients (150 eyes in 150 cases) receiving phacoemulsification in eye center affiliated second hospital of Zhejiang university were randomized into three groups: levofloxacin 0. 5%, 50 eyes; gatifloxacin 0. 3%, 50 eyes and levofloxacin 0. 3% ,50 eyes. Each group was randomized into five sub-groups ,with 10 eyes in each sub-group. Each group received either levofloxacin 0. 5% or topical gatifloxacin 0. 3% or levofloxacin 0. 3% preoperatively. One drop of antibiotic was administered every 15 minutes for 4 doses. More than 100 μl aqueous samples were obtained from different sub-groups during surgery,15.0,30. 0,60. 0, 120.0 and 180. 0 min after the last drop,respectively. Then 100 μl aqueous samples were put into test tube by sample injector accurately. Concentration of the antimicrobial agents was determined by the HPLC ( high pressure liquidchromatography). Variance analysis was performed to detect differences among the antibiotic treatment groups. The differences between two groups were assumed by t-test. Results Humor concentration of levofloxacin 0. 5% ( 1.61 ± 0. 48 ), ( 2.41 ±0. 80 ), ( 2. 93 ± 0. 50 ), ( 2. 56± 0. 63 ), ( 1.87±0. 88 ) mg/L was significantly higher than that of gatifloxacin 0. 3% ( 0. 70± 0. 18 ), ( 1.29 ± 0. 54 ), ( 1.59 ± 0. 67 ), (1.41±0.50),(1.13 ±0.28 )mg/L and levofloxacin0.3% (0.55±0.39),(1.15 ±0.42),(1.38 ± 0.49), ( 1.02 ± 0. 33 ), (0. 55 ± 0. 31 ) mg/L at the same period after the last drop ( F = 23.64,12. 82, 21.13,25.00,12. 22 ;P 〈 0. 05 ). Conclusion Topically applied levofloxacin 0. 5% had the higher aqueous humor drug level than gatifloxacin 0. 3% and levofloxacin 0. 3%.
