Clinical efficacy of moxifloxacin in the treatment of bacterial keratitis: a randomized clinical trial
Abstract
PURPOSE
To determine the clinical efficacy and safety of moxifloxacin (1.0%) in patients with bacterial keratitis compared with patients treated with ofloxacin (0.3%) or fortified tobramycin (1.33%)/cephazolin (5%).
DESIGN
Prospective randomized trial.
PARTICIPANTS
A total of 229 patients diagnosed with bacterial keratitis were enrolled in the study; 78 patients were randomized to the fortified tobramycin/cephazolin group, 77 patients to the moxifloxacin group, and 74 patients to the ofloxacin group. A total of 225 patients were evaluable for safety and 198 patients were included in the efficacy analysis.
INTERVENTION
After corneal specimens were obtained, the assigned study medication was instilled every hour, day and night, for 48 hours and on the third day, every hour by day and every 2 hours at night. For days 4 and 5, 1 drop every 2 hours by day and every 4 hours at night, and for days 6 and 7, 1 drop every 4 hours. After day 7, the antibiotic was tapered to every 6 hours and stopped when appropriate.
MAIN OUTCOME MEASURES
Resolution of keratitis and healing of ulcer, time to cure, mean time to discharge, clinical sign score, adverse reactions to study medication, and treatment failures.
RESULTS
Of the 186 nonexiting patients, resolution of the keratitis and healing of the ulcer occurred in 175 (94%) nonexiting patients. In the 175 patients in whom the corneal ulcer was cured, there were no statistically significant differences between the treatment groups for the mean…
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. Reported size: 229 participants or records.
