Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
DNA gyrase inhibitor; topoisomerase IV inhibitor; bactericidal against Gram-positive and Gram-negative bacteria by blocking DNA replication.
Moxifloxacin is a fluoroquinolone antibiotic that inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, thereby interfering with DNA replication, transcription, repair, and recombination.
1-2 drops of 0.5% solution in affected eye(s) every 2 hours while awake for 2 days, then 1-2 drops every 4 hours while awake for up to 5 days total.
400 mg orally every 24 hours for 7-14 days.

Terminal elimination half-life is approximately 4-6 hours. This short half-life supports twice-daily dosing in clinical practice (for ophthalmic suspension).
Terminal elimination half-life: 6-8 hours; prolonged in renal impairment (up to 20 hours with CrCl <30 mL/min).
Primarily renal excretion of unchanged drug (approximately 70-80%). A smaller fraction is excreted as metabolites via the kidneys. Biliary/fecal elimination accounts for less than 10% of the dose.
Renal: ~70% unchanged; biliary/fecal: ~20% as unchanged drug and metabolites; minor metabolism via glucuronidation.
