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.
Fluoroquinolone antibiotic that inhibits bacterial DNA gyrase and topoisomerase IV, preventing DNA replication and transcription.
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.
500 mg orally once daily with food.

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."

"Ciprofloxacin may decrease the cardiotoxic activities of Acetyldigitoxin."
Terminal elimination half-life is approximately 10-14 hours in patients with normal renal function (CrCl >80 mL/min). Extended half-life may occur in renal impairment, necessitating dose adjustment.
Renal (50-70% unchanged via glomerular filtration and tubular secretion); fecal (15-25% via biliary and transintestinal elimination); <1% as metabolites
Primarily renal excretion of unchanged drug (~60-80%) via glomerular filtration and tubular secretion. Biliary/fecal excretion accounts for approximately 20-35%, with a small portion as metabolites.
