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.
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 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.
400 mg orally twice daily for 3-14 days depending on indication.

4 hours (3-5 hours) in normal renal function; prolonged to 8-12 hours in moderate renal impairment (CrCl 20-50 mL/min) and 12-24 hours in severe impairment (CrCl <20 mL/min)
Clinical Note
moderateCiprofloxacin + Digoxin
"Ciprofloxacin may decrease the cardiotoxic activities of Digoxin."

moderateCiprofloxacin + Digitoxin
"Ciprofloxacin may decrease the cardiotoxic activities of Digitoxin."
Clinical Note
moderateCiprofloxacin + Deslanoside
"Ciprofloxacin may decrease the cardiotoxic activities of Deslanoside."
Clinical Note
moderateCiprofloxacin + Acetyldigitoxin
"Ciprofloxacin may decrease the cardiotoxic activities of Acetyldigitoxin."
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.
Renal (50-70% unchanged via glomerular filtration and tubular secretion); fecal (15-25% via biliary and transintestinal elimination); <1% as metabolites
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.
