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.
Inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, preventing DNA replication and transcription.
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.
400 mg orally or intravenously every 12 hours for 7-14 days; for uncomplicated gonorrhea, 400 mg as a single oral dose.

12.5 hours (range 10-16 hours), supporting once-daily dosing.
Terminal elimination half-life is 4-8 hours in adults with normal renal function; prolonged to 20-50 hours in severe renal impairment (CrCl <20 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.
Approximately 70-90% of an oral dose is excreted unchanged in urine via glomerular filtration and tubular secretion; about 4-8% is excreted in feces as unchanged drug and metabolites.
