CIPRO vs FACTIVE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ciprofloxacin inhibits bacterial DNA gyrase and topoisomerase IV, preventing DNA replication and transcription, leading to bacterial cell death.
Gemifloxacin inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, thereby interfering with DNA replication, transcription, repair, and recombination.
Ciprofloxacin 500 mg PO q12h or 400 mg IV q12h for uncomplicated infections; 750 mg PO q12h or 400 mg IV q8h for severe/complicated infections.
400 mg orally once daily for 5 days for acute exacerbation of chronic bronchitis; 400 mg orally once daily for 7 days for community-acquired pneumonia; 400 mg orally once daily for 5 days for acute bacterial sinusitis.

Terminal elimination half-life: 3-5 hours (normal renal function), extended to 8-10 hours in mild-to-moderate renal impairment (CrCl 30-50 mL/min) and up to >10 hours in severe impairment (CrCl <30 mL/min); half-life in elderly may be 5-8 hours due to reduced clearance.
12.5 hours (range 10-16 hours), supporting once-daily dosing.
Renal (50-70% unchanged via glomerular filtration and tubular secretion); biliary/fecal (15-20%, primarily as metabolites); small amount metabolized to 4 metabolites (oxo-, sulfo-, and desethylene-ciprofloxacin).
Renal excretion of unchanged drug accounts for approximately 61% of the administered dose; fecal elimination accounts for about 35%, with a minor biliary component.
