Management of fluoroquinolone use to avoid microbial resistance in clinical practice

Area of Science:

• Microbiology
• Pharmacology
• Infectious Diseases

Background:

• Fluoroquinolones are critical antimicrobial agents widely used in medicine.
• Increasing bacterial resistance to fluoroquinolones threatens their clinical efficacy.
• Pathogens like *Pseudomonas aeruginosa*, *Escherichia coli*, *Streptococcus pneumoniae*, *Neisseria gonorrhoeae*, and *Staphylococcus aureus* exhibit significant fluoroquinolone resistance.

Purpose of the Study:

• To address the challenge of rising antimicrobial resistance to fluoroquinolones.
• To explore strategies for preserving the effectiveness of existing fluoroquinolone antimicrobials.
• To ensure the prolonged utility of this important drug class.

Main Methods:

• Review of existing literature and clinical experience regarding fluoroquinolone use and resistance.
• Analysis of potential strategies to mitigate resistance development.
• Evaluation of antimicrobial stewardship principles for fluoroquinolone prescribing.

Main Results:

• Bacterial resistance has compromised the effectiveness of many fluoroquinolones.
• Several key bacterial pathogens have developed resistance to this drug class.
• Newer, more potent fluoroquinolones may offer improved activity.

Conclusions:

• Judicious prescribing of fluoroquinolones, reserving them for necessary cases, is crucial.
• Utilizing newer, more potent fluoroquinolones over older ones can enhance treatment outcomes.
• Employing combination antimicrobial therapy may increase coverage and achieve synergistic effects, prolonging the useful life of fluoroquinolones.
