Comparison of once-daily extended-release ciprofloxacin and conventional twice-daily ciprofloxacin for the treatment of uncomplicated urinary tract infection in women.

Background: Trimethoprim/sulfamethoxazole (TMP/SMX) is currently the first choice for empiric therapy of acute uncomplicated urinary tract infection (UTI) in women. In areas where resistance to TMP/SMX is known to be high, ciprofloxacin and other fluoroquinolones are recommended as first-line choices for the empiric therapy of UTI.

Objective: This study compared the efficacy and safety profile of once-daily extended-release ciprofloxacin 500 mg (referred to hereafter as ciprofloxacin QD) with those of conventional ciprofloxacin 250 mg BID, each administered orally for 3 days, in the treatment of uncomplicated UTI in women.

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.
