The emergence of Streptococcus pneumoniae that is resistantto the -lactam and macrolide antimicrobial drugs has arousedconcern about the use of these agents for the empirical treatmentof community-acquired pneumonia.1 Fluoroquinolones with increasedactivity against S. pneumoniae, such as levofloxacin, moxifloxacin,and gatifloxacin, are now being recommended for the treatmentof patients with community-acquired pneumonia whose infectionis likely to have been caused by multidrug-resistant strains.1,2,3,4,5,6However, there has been relatively little experience with theuse of these agents, as compared with the -lactam and macrolideantimicrobial agents, as monotherapy for community-acquiredpneumonia.
