Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits DNA gyrase (topoisomerase II) and topoisomerase IV, preventing bacterial DNA replication, transcription, and repair.
Quixin (levofloxacin) is a fluoroquinolone antibiotic that inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, thereby interfering with DNA replication, transcription, repair, and recombination.
400 mg IV every 12 hours or 500 mg orally every 12 hours for uncomplicated infections; 400 mg IV every 8 hours or 750 mg orally every 12 hours for severe/complicated infections.
