Efficacy and safety of topical ciprofloxacin/dexamethasone versus neomycin/polymyxin B/hydrocortisone for otitis externa.

OBJECTIVES: To compare the efficacy and safety of ciprofloxacin 0.3%/dexamethasone 0.1% (CIP/DEX) otic suspension with that of neomycin 0.35%/polymyxin B 10,000 IU/mL/hydrocortisone 1.0% (N/P/H) otic suspension in patients with acute otitis externa (AOE). STUDY DESIGN: Randomized, observer-masked, parallel-group, multicenter study. Patients were randomized to 7 days treatment with either CIP/DEX 3-4 drops twice daily or N/P/H 3-4 drops three times daily. POPULATION: Patients of either sex and older than 1 year, with a clinical diagnosis of mild, moderate, or severe AOE and intact tympanic membranes were recruited to participate. OUTCOMES MEASURED: Signs and symptoms of AOE, including ear inflammation, tenderness, edema and discharge (assessed on Days 3, 8 [End-of-Therapy] and 18 [Test-of-Cure]); microbiologic eradication (presumed or documented); and frequency of adverse events. RESULTS: Patients enrolled numbered 468. In culture-positive patients who met the inclusion criteria (N = 396), clinical cure rates at Day 18 were significantly higher with CIP/DEX than with N/P/H (90.9% vs. 83.9%; p = 0.0375), as were microbiologic eradication rates (94.7% vs. 86.0%; p = 0.0057). In addition, the clinical response was significantly better with CIP/DEX than with N/P/H at Days 3 and 18 (p = 0.0279 and p = 0.0321, respectively), as was the reduction in ear inflammation at Day 18 (p = 0.0268). Both preparations were well tolerated in pediatric and adult patients. CONCLUSIONS: 7 days treatment with CIP/DEX otic suspension administered twice daily is clinically and microbiologically superior to N/P/H otic suspension administered 3 times daily in the treatment of mild to severe AOE, and is equally well tolerated.

Topical ciprofloxacin/dexamethasone otic suspension is superior to ofloxacin otic solution in the treatment of granulation tissue in children with acute otitis media with otorrhea through tympanostomy tubes.

OBJECTIVE: Comparison of topical ciprofloxacin/dexamethasone otic suspension (CIP/DEX) to ofloxacin otic solution (OFL) for treatment of granulation tissue in children with AOMT. STUDY DESIGN: 599 children aged >/=6 months to 12 years with AOMT of up to 3 weeks' duration were enrolled. Patients received either CIP/DEX 4 drops twice daily for 7 days or OFL 5 drops twice daily for 10 days. Granulation tissue severity was graded at clinic visits on days 1, 3, 11, and 18. RESULTS: Granulation tissue was present in 90 of 599 AOMT patients (15.0%) at baseline. CIP/DEX treatment was superior to OFL for reduction of granulation tissue at the day 11 visit (81.3% compared with 56.1%, P = 0.0067) and the day 18 visit (91.7% compared with 73.2%, P = 0.0223). Both topical otic preparations are safe and well tolerated in pediatric patients. CONCLUSION: CIP/DEX was superior to OFL in the treatment of granulation tissue in children with AOMT.

Topical ciprofloxacin/dexamethasone otic suspension is superior to ofloxacin otic solution in the treatment of children with acute otitis media with otorrhea through tympanostomy tubes.

OBJECTIVE: To determine the efficacy and safety of topical ciprofloxacin/dexamethasone otic suspension compared with ofloxacin otic solution in the treatment of acute otitis media with otorrhea through tympanostomy tubes (AOMT) in pediatric patients. METHODS: This multicenter, prospective, randomized, observer-masked, parallel-group study was conducted at 39 sites in 599 children aged >or=6 months to 12 years with an AOMT episode of

Topical ciprofloxacin/dexamethasone is superior to ciprofloxacin alone in pediatric patients with acute otitis media and otorrhea through tympanostomy tubes.

OBJECTIVE: To determine whether topical administration of a corticosteroid improves resolution of acute tympanostomy tube otorrhea when combined with topical antibiotic drops. STUDY DESIGN: Randomized, patient-masked, parallel-group, multicenter trial of topical otic ciprofloxacin/dexamethasone versus topical ciprofloxacin alone in 201 children aged 6 months to 12 years with acute otitis media with tympanostomy tubes (AOMT) of less than or equal to 3 weeks' duration and visible otorrhea. METHODS: Eligible patients were randomized to receive three drops of either ciprofloxacin 0.3%/dexamethasone 0.1% or ciprofloxacin 0.3% into the affected ear or ears twice daily for 7 days. Clinical signs and symptoms of AOMT were evaluated on days 1 (baseline), 3, 8 (end-of-therapy), and 14 (test-of-cure), and twice-daily assessments of otorrhea were recorded in patient diaries. RESULTS: The mean time to cessation of otorrhea in the microbiologically culture-positive patient population (n = 167) was significantly shorter with topical ciprofloxacin/dexamethasone than with ciprofloxacin alone (4.22 vs. 5.31 days; P =.004). This resulted in significantly better clinical responses on days 3 and 8 (P <.0001 and P =.0499, respectively). However, there were no significant differences between the two treatment groups in either the clinical response or the microbial eradication rate by day 14. CONCLUSIONS: Topical otic treatment with ciprofloxacin/dexamethasone is superior to treatment with ciprofloxacin alone and results in a faster clinical resolution in children with AOMT. The contribution of the corticosteroid in achieving a 20% reduction (1.1 day) in time to cessation of otorrhea is clinically meaningful and represents an important advance over single-agent antibiotic therapy.
