Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, preventing DNA replication and transcription.
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 orally or intravenously every 12 hours for 7-14 days; for uncomplicated gonorrhea, 400 mg as a single oral dose.
One to two drops in affected eye(s) every 2 hours while awake, up to 8 times daily for 7-14 days.

Terminal elimination half-life: 6–8 hours in adults with normal renal function; prolonged in renal impairment (up to 20 hours if CrCl <30 mL/min).
Approximately 70-90% of an oral dose is excreted unchanged in urine via glomerular filtration and tubular secretion; about 4-8% is excreted in feces as unchanged drug and metabolites.
Renal (approximately 70% unchanged in urine); biliary/fecal (~30%, partly as metabolites and unchanged drug).
