Comparative Analysis of Nemonoxacin and Other Anti-methicillin Resistant Staphylococcus Aureus (Anti-MRSA) Antimicrobial Therapy in Patients With Complicated Skin and Soft Tissue Infections (cSSTI): a Retrospective Chart Review Study

Increasing rates of antimicrobial resistant bacterial infections and antimicrobial therapy at home in elderly are great concern for medical care. The availability of new antibacterial agents that are effective against bacteria with resistance to other antibacterials is therefore critical to continued successful management of bacterial illnesses in the future. Nemonoxacin is a C-8 methoxy, non-fluorinated quinolone that retains potent broad-spectrum activities against Gram-positive and Gram-negative bacteria by selective inhibition of bacterial DNA topoisomerase. Nemonoxacin had greater in-vitro activity against many Gram-positive bacteria, including methicillin-susceptible S. aureus (MSSA), and ciprofloxacin-susceptible and ciprofloxacin-resistant MRSA, levofloxacin-susceptible and levofloxacin-resistant S. pneumoniae, Streptococcus pyogenes, Streptococcus agalactiae, enterococci, and Enterobacterieacea species except Pseudomonas aeruginosa. Lowe selected mutation of Nemonoxacin, compared with other fluoroquinolones against antimicrobial resistant gram-positive bacteria had been reported.\[5\] Nemonoxacin could be used once-daily oral and intravenous formulations for the treatment of community-acquired pneumonia, including methicillin resistant Staphylococcus aureus (MRSA). However, nemonoxacin has less evidence of efficacy for complicated skin and soft tissue infection. In this retrospective study, we will investigate the treatment outcomes of nemonoxacin and compared with other anti-methicillin resistant Staphylococcus aureus (anti-MRSA) antimicrobial therapy in patients with complicated skin and soft tissue infections (cSSTI) by chart review.
