ABT-492 exhibited excellent in vitro activities against all 326 aerobic and anaerobic antral puncture sinus isolates tested with MICs (in micrograms per milliliter) at which 90% of the isolates tested were inhibited as follows: Haemophilus influenzae, 0.001; Moraxella catarrhalis, 0.008; and Streptococcus pneumoniae, 0.015. It was four- to sixfold more active than other fluoroquinolones, including against levofloxacin-resistant strains of S. pneumoniae, methicillin-resistant Staphylococcus aureus, and Prevotella species.
