GATIFLOXACIN vs IQUIX
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.
DNA gyrase inhibitor; topoisomerase IV inhibitor; bactericidal against Gram-positive and Gram-negative bacteria by blocking DNA replication.
400 mg orally or intravenously once daily
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.

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)

Terminal elimination half-life is approximately 4-6 hours. This short half-life supports twice-daily dosing in clinical practice (for ophthalmic suspension).
Primarily renal excretion (70-87% unchanged in urine) via glomerular filtration and tubular secretion; ~10% biliary/fecal
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.
