Description
A synthetic fluoroquinolone (fluoroquinolones) antibacterial agent that inhibits the supercoiling activity of bacterial DNA gyrase, halting DNA replication.
Indication
For the treatment of bacterial conjunctivitis caused by susceptible strains of the following organisms: Corynebacterium species, Staphylococus aureus, Staphylococcus epidermidis, Streptococcus pneumoniae, Streptococcus (Groups C/F/G), Viridans group streptococci, Acinetobacter lwoffii, Haemophilus influenzae, Serratia marcescens.
Mechanism of Action
Levofloxacin 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.
