Area of Science:

  • Microbiology
  • Pharmacology
  • Infectious Diseases

Background:

  • Lomefloxacin is a new difluorinated quinolone antibiotic.
  • Quinolones are a class of synthetic broad-spectrum antibacterial drugs.

Purpose of the Study:

  • To evaluate the in vitro antibacterial activity of lomefloxacin.
  • To compare lomefloxacin's activity with other quinolones.
  • To assess the development of bacterial resistance to lomefloxacin.

Main Methods:

  • In vitro comparative antibacterial studies.
  • Testing against a wide range of aerobic gram-negative and gram-positive bacteria, including resistant strains.
  • Assessment of spontaneous single-step resistance development.

Main Results:

  • Lomefloxacin exhibited broad in vitro antibacterial activity, comparable or superior to other quinolones (except ciprofloxacin).
  • It was effective against Neisseria gonorrhoeae, Moraxella catarrhalis, Haemophilus influenzae, Pseudomonas aeruginosa, and Staphylococcus aureus.
  • Susceptible activity was observed against organisms resistant to methicillin, penicillin, or aminoglycosides.
  • Low frequency of spontaneous single-step resistance development was noted globally, with minimal exceptions.

Conclusions:

  • Lomefloxacin possesses significant in vitro antibacterial activity against a broad spectrum of pathogens.
  • It demonstrates efficacy against multidrug-resistant organisms.
  • The low rate of resistance development suggests clinical utility.
