Delafloxacin: a novel fluoroquinolone with activity against methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa.

INTRODUCTION: The resistance to current antimicrobial agents, including fluoroquinolones, has continued to grow among various pathogens indicating a need for new antimicrobials to combat multi-drug resistant (MDR) organisms. In June 2017, delafloxacin received approval by the US Food and Drug Administration for the treatment of acute bacterial skin and skin-structure infections (ABSSSIs) in adults caused by designated susceptible bacteria. Areas covered: This review describes the pharmacology, pharmacodynamics, pharmacokinetics, product information, efficacy, and safety of delafloxacin. Expert commentary: Delafloxacin is a novel oral and intravenous fluoroquinolone with activity against methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa, offering a new option for the treatment of ABSSSI and potentially for complicated urinary tract infections and severe community-acquired bacterial pneumonia.
