Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibition of bacterial DNA gyrase and topoisomerase IV, preventing DNA replication, transcription, repair, and recombination.
Noroxin (norfloxacin) is a fluoroquinolone antibacterial agent that inhibits DNA gyrase (topoisomerase II) and topoisomerase IV, enzymes required for bacterial DNA replication, transcription, repair, and recombination.
400 mg orally every 12 hours for 10-14 days; ophthalmic solution: 1-2 drops in affected eye(s) every 2-4 hours for 2 days, then 1-2 drops 4 times daily for 10 days; otic solution: 5-10 drops in affected ear(s) twice daily for 10-14 days.
400 mg orally twice daily for 3-14 days depending on indication.

Terminal elimination half-life of 10-14 hours in patients with normal renal function; prolonged in renal impairment (up to 40-50 hours in severe cases).
Terminal elimination half-life is 6-7 hours in patients with normal renal function. Prolonged to 21-28 hours in severe renal impairment (CrCl <30 mL/min), requiring dose adjustment.
Approximately 70-90% excreted unchanged in urine via glomerular filtration and tubular secretion; about 10-30% eliminated in feces via biliary excretion.
Renal excretion accounts for approximately 30% of the dose as unchanged drug. Biliary/fecal elimination is a major route, with about 60-70% recovered in feces as unchanged drug and metabolites.
