FACTIVE vs GATIFLOXACIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Gemifloxacin inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, thereby interfering with DNA replication, transcription, repair, and recombination.
Gatifloxacin inhibits bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication, transcription, repair, and recombination.

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 excretion of unchanged drug accounts for approximately 61% of the administered dose; fecal elimination accounts for about 35%, with a minor biliary component.
Primarily renal excretion (70-87% unchanged in urine) via glomerular filtration and tubular secretion; ~10% biliary/fecal
