Comparative research of the efficacy of the gatifloxacin and levofloxacin for bacterial conjunctivitis in human eyes
Abstract
OBJECTIVE: To evaluate the different efficacy and safety to the treatment of bacterial conjunctivitis between the fluoroquinolone antibiotics gatifloxacin and levofloxacin.
METHODS: A multi-centre, random, double-blind and control trial was performed in six centers including Eye Ear Nose and Throat Hospital of Fudan University, Henan Eye Institute, Eye Hospital Affiliated to Wenzhou Medical College, the First Affiliated Hospital Of Nanjing Medical University, Xijing Hospital Affiliated to the Fourth Military Medical University, the Second Affiliated Hospital of Xi'an Jiaotong University between August 2006 and October 2007. The levofloxacin was set as the efficient control. Two hundred and thirty-five patients (235 eyes) that diagnosed as bacterial conjunctivitis were randomly divided into two groups by the method of randomized blocks, the test group (gatifloxacin) had 118 eyes and the control (levofloxacin) group had 117 eyes. The drug delivery into conjunctival sac was performed at a 7-day period (two drops per time, eight times per day at the first two days and two drops per time, four times per day at the following 5 days). All participants were given the conjunctival sac germ culture and drug sensitive test before and after the study. The combination score of signs and symptoms and evaluation of safety were conducted at the pre-delivery day, the (4 ± 1) and (7 ± 1) delivery day. The statistic analysis was conducted by CMH χ(2) test, Pearson χ(2) test and Fisher's exact…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
