Efficacy and safety of sequential moxifloxacin for treatment of community-acquired pneumonia associated with atypical pathogens.

In two prospective, randomized studies intravenous (IV)/oral (PO) moxifloxacin (400 mg q.i.d.) was compared to IV/PO antimicrobial comparator agents for the treatment of hospitalized patients with community-acquired pneumonia. Reported here are the pooled data for the sub-population with atypical pathogens. Of 101 intent-to-treat patients with atypical pathogens, a total of 39 moxifloxacin-treated and 47 comparator-treated subjects were microbiologically valid and included in the analysis. Clinical and bacteriological success rates were 95% for the moxifloxacin-treated and 94% for the comparator-treated subjects at the test-of-cure visit. The results indicate IV/PO moxifloxacin (400 mg q.i.d.) is an effective monotherapy for patients with CAP due to atypical pathogens.
