[Multicenter study comparing the efficacy and tolerance of topical ciprofloxacin (0.3%) versus topical gentamicin (0.3%) in the treatment of simple, non-cholesteatomaous chronic otitis media in the suppurative phase].

A multicentre double-blind randomized study was carried out to compare topical ciprofloxacin and topical gentamicin in the treatment of simple non-cholesteatomatous purulent chronic otitis media. Three hundred and eight patients were included in the study, 159 treated with ciprofloxacin and 149 treated with gentamicin. The percentage of clinical success (elimination of otorrhoea) was 95% with ciprofloxacin and 94% with gentamicin (ns). Likewise, the percentage of bacteriological erradication was 96% with ciprofloxacin and 93% with gentamicin. Both drugs were well tolerated, without changes in the audiometric values. In these patients, topical ciprofloxacin shows the same efficacy as topical gentamicin without any potential ototoxic effect.
