The purpose of this study is to assess the Safety and Efficacy of Foam Otic Cipro, a novel medication developed to treat Acute Diffuse Otitis Externa of bacterial origin.

The working hypothesis is that Foam Otic Cipro is as effective as registered ear drops.

Detailed Description:
Acute otitis externa (AOE) is defined as a diffuse inflammation of the external ear canal, which may also involve the pinna and/or the tympanic membrane. AOE is one of the most common infections encountered by otolaryngologists, pediatricians and family physicians. The reported annual incidence of AOE is between 1:100 and 1:250 in the general population with large seasonal and regional variations. Diagnosis of AOE requires rapid onset (generally within 48 hours) of symptoms and signs of ear canal inflammation which includes: A) otalgia (often severe), itching or fullness, sometimes accompanied by reduced hearing or jaw pain; B) tenderness of the tragus and/or pinna; and C) diffuse ear canal edema with or without erythema, sometimes accompanied by ear discharge.

  • Intact tympanic membrane
  • Unilateral Acute Otitis Externa

Exclusion Criteria:

  • Known allergy or sensitivity to Ciprofloxacin or other quinolones.
