CIPRO vs GATIFLOXACIN
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.
Gatifloxacin inhibits bacterial DNA gyrase and topoisomerase IV, enzymes essential for 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 or intravenously once daily

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.

Terminal elimination half-life 7-14 hours (mean ~10 hours in healthy adults); prolonged in renal impairment (up to 40 hours with CrCl <30 mL/min)
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).
Primarily renal excretion (70-87% unchanged in urine) via glomerular filtration and tubular secretion; ~10% biliary/fecal
