Comparison of efficacy and safety of ciprofloxacin otic solution 0.2% versus polymyxin B-neomycin-hydrocortisone in the treatment of acute diffuse otitis externa
2008
ABSTRACTObjective: To compare the efficacy and safety of ciprofloxacin otic solution 0.2% to polymyxin B-neomycin-hydrocortisone (PNH) otic solution in the treatment of acute diffuse otitis externa in children, adolescents, and adults.Methods: This was a randomized, parallel-group, evaluator-blind, active-controlled, multicenter, noninferiority study. The primary efficacy endpoint was clinical cure of otitis symptoms at the test-of-cure (TOC) visit. Clinical cure at the end-of-treatment (EOT) visit and percentages of patients with clinical improvement and resolution and/or improvement of otalgia at EOT and TOC visits were secondary efficacy endpoints.Results: A total of 630 patients were randomized to ciprofloxacin twice daily (n = 318) or PNH 3 times daily (n = 312) for 7 days. Ciprofloxacin was shown to be noninferior to PNH. The percentage of patients with clinical cure at the TOC visit was 86.6% with ciprofloxacin and 81.1% with PNH; the treatment difference was 5.6% in favor of ciprofloxacin (95% CI:...
