Brief Summary

Roxithromycin is used for the treatment of pharyngitis and tonsillitis caused by Streptococcus pyogenes, sinusitis, otitis media, acute bronchitis, acute exacerbations of chronic bronchitis, and pneumonia caused by Mycoplasma pneumoniae or Chlamydia pneumoniae; urethritis and cervicitis caused by Chlamydia trachomatis; and skin and soft tissue infections caused by susceptible bacteria.

The purpose of this study was to evaluate the bioequivalence of roxithromycin tablets from two different manufacturers after fasting administration in healthy subjects and to observe the safety of the test and reference preparations in healthy subjects.
