Topical ciprofloxacin/dexamethasone superior to oral amoxicillin/clavulanic acid in acute otitis media with otorrhea through tympanostomy tubes.

OBJECTIVE: This study was a comparison of topical ciprofloxacin/dexamethasone otic suspension to oral amoxicillin/clavulanic acid suspension in children with acute otitis media with otorrhea through tympanostomy tubes. METHODS: This was a randomized, observer-masked, parallel-group, multicenter trial of topical ciprofloxacin/dexamethasone otic suspension versus amoxicillin/clavulanic acid suspension in 80 children aged 6 months to 12 years with acute otitis media with otorrhea through tympanostomy tubes of < or = 3 weeks' duration and visible otorrhea. Patients were randomly assigned to receive either 4 drops of topical ciprofloxacin 0.3%/dexamethasone 0.1% (Ciprodex Sterile Otic Suspension) into the affected ear(s) twice daily for 7 days or 600 mg of amoxicillin/42.9 mg of clavulanic acid oral suspension (Augmentin ES-600 Oral Suspension) every 12 hours for 10 days. Clinical signs and symptoms of acute otitis media with otorrhea through tympanostomy tubes were evaluated on days 1 (baseline), 3, 11 (end-of-therapy), and 18 (test-of-cure), and twice-daily assessments of otorrhea were recorded in patient diaries. RESULTS: The median time to cessation of otorrhea was significantly shorter with ciprofloxacin/dexamethasone otic suspension than with amoxicillin/clavulanic acid suspension (4.0 vs 7.0 days; n = 79). This resulted in significantly more clinical cures at the test-of-cure visit (85% vs 59%, respectively). Frequent adverse events (> 3%) related to ciprofloxacin/dexamethasone otic suspension included ear pain (5.1%) and related to amoxicillin/clavulanic acid suspension included diarrhea (19.5%), dermatitis (7.3%), and gastroenteritis (4.9%). CONCLUSIONS: Topical otic treatment with ciprofloxacin/dexamethasone otic suspension is superior to treatment with oral amoxicillin/clavulanic acid suspension and results in more clinical cures and earlier cessation of otorrhea with fewer adverse effects in children with acute otitis media with otorrhea through tympanostomy tubes.

Controlling contagious bacterial conjunctivitis.

BACKGROUND: Recent outbreaks (epidemics) of Streptococcus pneumoniae conjunctivitis, involving hundreds of patients, underscore the importance of following recommended guidelines to minimize disease transmission. These include the use of antimicrobial agents capable of minimizing patients' symptoms and the duration of the infectious period when disease can be transmitted to others. PURPOSE: To compare the amount of time required forvarious antibiotic solutions to kill S. pneumoniae, a common cause of bacterial conjunctivitis. MATERIALS AND METHODS: Isolates of S. pneumoniae from three patients were exposed to selected ophthalmic antibiotic products: moxifloxacin 0.5%, tobramycin 0.3%, gentamicin 0.3%, and polymyxin B 10,000 IU-trimethoprim 1.0%. The products were diluted 1:100 and 1:1000 for testing. At 15, 30, 60, 120, and 180 minutes after exposure, aliquots of broth were withdrawn, the cells were separated and cultured, and the viable cell count was determined. RESULTS: Moxifloxacin killed actively growing S. pneumoniae faster and to a greater extent than did the other three antibiotic products when tested at concentrations corresponding to tear film concentrations 5 to 10 minutes and 30 to 60 minutes after instillation of the products. CONCLUSIONS: Moxifloxacin killed S. pneumoniae in vitro faster than did the other antibiotics. Consequently, its use should complement other generally accepted measures for minimizing patients' symptoms and limiting the contagiousness of bacterial conjunctivitis. Also, this is consistent with the recommendations of other investigators to prescribe the most recent generation of fluoroquinolone antibiotics for the specific purpose of limiting the spread of bacterial resistance.
