RESUMEN
The efficacy and safety of a once-daily oral regimen of 400 mg ceftibuten was compared with oral co-amoxiclav 500 mg three times daily in a multicentre, single-blind study. In patients with a bacteriologically confirmed infection, a successful clinical outcome was reported in 25 of 25 patients treated with ceftibuten and 10 of 10 patients treated with co-amoxiclav. In a further group of 88 patients, most of whom had been excluded from the primary efficacy evaluation because no pathogen was isolated pretreatment, overall successful clinical outcomes of 87% and 88% were reported for ceftibuten and co-amoxiclav, respectively. The duration of treatment and the time to resolution of the signs and symptoms of sinusitis were not significantly different in the two treatment groups. The incidence of adverse events was higher in the co-amoxiclav-treated patients (31% versus 15% in the ceftibuten group) as was the incidence of severe events (10% for co-amoxiclav-treated patients versus < 1% in the ceftibuten group). In summary, once-daily ceftibuten can be considered a safe and effective treatment for acute bacterial sinusitis.
