A multicenter, randomized, investigator-blinded study of 5- and 10-day gatifloxacin versus 10-day amoxicillin/clavulanate in patients with acute bacterial sinusitis.

Background: Treatment guidelines for acute bacterial sinusitis recommend 10 to 14 days of therapy with amoxicillin/clavulanate, high-dose amoxicillin, cefpodoxime, cefuroxime, or a newer fluoroquinolone.

Objective: This study compared the clinical efficacy of short-course (5-day) gatifloxacin with standard 10-day regimens of amoxicillin/clavulanate or gatifloxacin in patients with a diagnosis of acute, uncomplicated maxillary sinusitis.

Methods: This was a multicenter, investigator-blinded study in adult patients (age >18 years) with physical findings, signs and symptoms (for at least 7 days), and radiographic findings indicating acute, uncomplicated maxillary sinusitis.

A comparison of a five-day regimen of cefdinir with a seven-day regimen of loracarbef for the treatment of acute exacerbations of chronic bronchitis.

To compare the efficacy and safety of five-day cefdinir treatment with seven-day loracarbef treatment in patients with acute exacerbations of chronic bronchitis, 586 patients were enrolled in a multicentre, randomised, double-blind trial. Patients received either five days of treatment with cefdinir (n = 291) at 300 mg twice daily or seven days of treatment with loracarbef (n = 295) at 400 mg twice daily. Microbiological assessments were done on sputum specimens obtained at admission and at the two post-therapy visits, if available.

Comparison of ceftibuten once daily and amoxicillin-clavulanate three times daily in the treatment of acute exacerbations of chronic bronchitis.

In medical practice, antibiotics are generally given empirically for the treatment of acute exacerbations of chronic bronchitis (AECB). To be effective, antibiotic therapy should be broad in spectrum, and it should also cover the common beta-lactamase-producing pathogens. In this multicenter, randomized, investigator-masked study, 469 patients with AECB were randomized (in a ratio of 2:1) to receive 400-mg oral ceftibuten capsules once daily or 500-mg amoxicillin-clavulanate tablets three times daily for 5 to 15 days.
