Brand Names

  • Ava-levofloxacin
  • Dom-levofloxacin
Affected OrganismEnteric bacteria and other eubacteria
IndicationFor the treatment of bacterial conjunctivitis caused by susceptible strains of the following organisms: <i>Corynebacterium</i> species, <i>Staphylococus aureus</i>, <i>Staphylococcus epidermidis</i>, <i>Streptococcus pneumoniae</i>, <i>Streptococcus</i> (Groups C/F/G), Viridans group streptococci, <i>Acinetobacter lwoffii</i>, <i>Haemophilus influenzae</i>, <i>Serratia marcescens</i>.
PharmacologyLevofloxacin, a fluoroquinolone antiinfective, is the optically active L-isomer of ofloxacin. Levofloxacin is used to treat bacterial conjunctivitis, sinusitis, chronic bronchitis, community-acquired pneumonia and pneumonia caused by penicillin-resistant strains of <i>Streptococcus pneumoniae</i>, skin and skin structure infections, complicated urinary tract infections and acute pyelonephritis.
Mechanism of actionLevofloxacin inhibits bacterial type II topoisomerases, topoisomerase IV and DNA gyrase. Levofloxacin, like other fluoroquinolones, inhibits the A subunits of DNA gyrase, two subunits encoded by the gyrA gene. This results in strand breakage on a bacterial chromosome, supercoiling, and resealing; DNA replication and transcription is inhibited.
