Description
Besifloxacin is a fourth generation fluoroquinolone-type opthalmic antibiotic for the treatment of bacterial conjunctivitis. FDA approved on May 28, 2009.
Indication
Treatment of bacterial conjunctivitis. Bacterial isolates that are susceptible to besifloxacin include: CDC coryneform group G; Corynebacterium pseudodiphtheriticum; Corynebacterium striatum; Haemophilus influenzae; Moraxella lacunata; Staphylococcus aureus; Staphylococcus epidermidis; Staphylococcus hominis; Staphylococcus lugdunensis; Streptococcus mitis group; Streptococcus oralis; Streptococcus pneumoniae; Streptococcus salivarius*
Mechanism of Action
Besifloxacin is a bactericidal fluroquinolone-type antibiotic that inhibits bacterial enzymes, DNA gyrase and topoisomerase IV. By inhibiting DNA gyrase, DNA replication, transcription, and repair is impaired. By inhibiting topoisomerase IV, decatenation during cell devision is impaired. Inhibiting these two targets also slows down development of resistance.
Pharmacokinetics
