GATIFLOXACIN vs MAXAQUIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Gatifloxacin inhibits bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication, transcription, repair, and recombination.
Fluoroquinolone antibiotic that inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, thereby interfering with DNA replication, transcription, repair, and recombination.
400 mg orally or intravenously once daily
400 mg orally once daily for 5-10 days; for complicated urinary tract infections, 400 mg orally once daily for 10-14 days.

Terminal elimination half-life is approximately 12 hours (range 10-14 hours), supporting twice-daily dosing for systemic infections.
Primarily renal excretion (70-87% unchanged in urine) via glomerular filtration and tubular secretion; ~10% biliary/fecal
Renal excretion of unchanged drug accounts for 70-80%; biliary/fecal elimination accounts for 20-30%.
