CHIBROXIN vs QUIXIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chibroxin (norfloxacin) is a fluoroquinolone antibiotic that inhibits bacterial DNA gyrase 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.
1-2 drops of 0.3% ophthalmic solution into affected eye(s) every 2 hours while awake for the first 2 days, then every 4 hours for 5-7 days.
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 to 12-24 hours in moderate renal impairment (CrCl 30-50 mL/min) and >24 hours in severe impairment (CrCl <30 mL/min).
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).
Renal: 98% as unchanged drug; hepatic: 2% as minor metabolites. Biliary/fecal excretion negligible.
Renal (approximately 70% unchanged in urine); biliary/fecal (~30%, partly as metabolites and unchanged drug).
