Levonadifloxacin is a novel benzoquinolizine subclass of fluoroquinolone, active against quinolone-resistantStaphylococcus aureus . A phase 3 trial for levonadifloxacin and its oral prodrug was recently completed. The present study identified area under the concentration-time curve for the free, unbound fraction of a drug divided by the MIC (f AUC/MIC) as an efficacy determinant for levonadifloxacin in a neutropenic murine lung infection model.
