Skin and skin structure infections: treatment with newer generation fluoroquinolones
Abstract:
Skin and skin structure infections (SSSI) are an emerging issue in healthcare. They are responsible for increasing heathcare utilization, both in hospitalizations and intravenous antibiotic use. SSSI are caused by an evolving variety of pathogens, including Gram-positive, Gram-negative, and anaerobic bacteria. In combination with mounting resistance patterns, this diverse range of bacteria mandate empiric broad-spectrum antibiotic coverage. Historically, cephalosporins and penicillins have been the mainstay of treatment, but recent data suggest newer generation fluoroquinolones are being used with increasing frequency. In 2005, moxifloxacin joined gatifloxacin and levofloxacin as newer generation fluoroquionolones with Food and Drug Administration indications for SSSIs. Even within this group there exist subtle differences that impact optimal management. This paper offers the clinician a comparative review of the antimicrobial spectrum, pharmacodynamics, pharmacokinetics, and clinical efficacy data to support the appropriate use of fluoroquinolones in SSSIs.
Insights
Skin and skin structure infections (SSSI) are increasing, necessitating broad-spectrum antibiotics. This review compares newer fluoroquinolones for optimal SSSI management, aiding clinical decision-making.
Area of Science:
- Infectious Diseases
- Pharmacology
- Clinical Medicine
Background:
- Skin and skin structure infections (SSSI) represent a growing healthcare challenge, leading to increased hospitalizations and antibiotic use.
- The diverse and evolving pathogens causing SSSI, including Gram-positive, Gram-negative, and anaerobic bacteria, coupled with rising resistance, demand broad-spectrum empiric antibiotic therapy.
- While historically treated with cephalosporins and penicillins, newer generation fluoroquinolones are increasingly utilized for SSSI management.
Purpose of the Study:
- To provide a comparative review of newer generation fluoroquinolones used for SSSI treatment.
- To analyze antimicrobial spectrum, pharmacodynamics, pharmacokinetics, and clinical efficacy of relevant fluoroquinolones.
- To support clinicians in making informed decisions regarding the appropriate use of fluoroquinolones in SSSI.
Main Methods:
- Comparative review of existing literature.
- Analysis of antimicrobial data.
- Evaluation of pharmacokinetic and pharmacodynamic properties.
- Assessment of clinical efficacy studies.
Main Results:
- Newer generation fluoroquinolones, including moxifloxacin, gatifloxacin, and levofloxacin, have FDA indications for SSSI.
- Subtle differences exist within this class of fluoroquinolones, impacting their optimal clinical application.
- Data on antimicrobial spectrum, pharmacodynamics, pharmacokinetics, and clinical efficacy are crucial for guiding treatment choices.
Conclusions:
- Appropriate selection of fluoroquinolones for SSSI requires careful consideration of their specific properties.
- This review aims to equip clinicians with the necessary data for effective fluoroquinolone utilization in SSSI.
- Optimizing fluoroquinolone use can lead to improved patient outcomes in managing skin and skin structure infections.
