The clinical efficacy of gatifloxacin eye drops for bacterial conjunctivitis

Objective To study the clinical efficacy of gatifloxacin eye drops for bacterial conjunctivitis.Methods A total of 240 cases that diagnosed as bacterial conjunctivitis were randomly divided into test group (gatifloxacin) and control group (floxacin).A random double-blind and paralled study was conducted on 120 cases with gatifloxacin and floxacin eye drops for bacterial conjunctivitis.The drug delivery into conjunctival sac was performed at 7-14 days (one-two drops per time, five times per day).Results Sixty-seven clinical common pathogenic bacteria were separated from the study.The antibacterial activity of gatifloxacin,floxacin, levofloxacin, ciprofloxacin was 98.51%, 85.07%, 95.52%, and 78.79% respectively.The antibacterial activity of gatifloxacin was the highest, and the statistic difference between gatifloxacin and floxacin was found.The effect of gatifloxacin eye drops was not worse than floxacin eye drops.Conclusions The gatifloxacin eye drops has characteristics with broad spectrum, powerfull antibacterial activity.The linical effect of gatifloxacin eye drops is the same with floxacin eye drops.Gatifloxacin eye drops are safe and can be used to treat bacterial conjunctivitis.It has comparatively theropic value of ocular surface disease with Gram-positive bacterial and Gram-negetive bacterial.
