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.
Amoxicillin (extended-release) inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin inhibitors, leading to cell lysis and death via activation of autolytic enzymes.
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.
775 mg orally once daily for 7 days.

12.5 hours (range 10-16 hours), supporting once-daily dosing.
The terminal elimination half-life is 1.0–1.5 hours in healthy adults; however, with the extended-release formulation (Moxatag), the effective half-life is prolonged to support once-daily dosing.
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 60% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion; about 20% is excreted in feces via biliary elimination.
