About

The study was performed to see if a single, 2.0-g oral dose of azithromycin sustained release (SR) was at least as effective as a 7-day regimen of levofloxacin (500 mg once daily) for the treatment of mild to moderate community-acquired pneumonia, and to assess the efficacy and safety of both treatment regimens.
