Synonyms:

  • lomeflon
  • lomefloxacin hydrochloride
  • lomefloxacin
  • lomefloxacin HCl
A synthetic broad-spectrum fluoroquinolone with antibacterial activity. Lomefloxacin inhibits DNA gyrase, a type II topoisomerase involved in the induction or relaxation of supercoiling during DNA replication. This inhibition leads to a decrease in DNA synthesis during bacterial replication, resulting in cell growth inhibition and eventually cell lysis.
