BESIVANCE vs ECONOCHLOR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BESIVANCE is a fluoroquinolone antibiotic that inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, thereby blocking DNA replication and leading to bacterial cell death.
Econazole nitrate inhibits fungal cytochrome P450 14α-demethylase, blocking ergosterol synthesis, disrupting fungal cell membrane integrity and function.
One drop instilled into the affected eye(s) three times daily for 7 days.
0.12 mg/kg IV bolus over 30 seconds, followed by continuous IV infusion at 0.12-0.6 mg/kg/h.

Terminal half-life of approximately 1.5-2 hours in adults; prolongation in renal impairment.
Terminal half-life: 8-10 hours in adults with normal renal function; prolonged to 15-20 hours in renal impairment (CrCl <30 mL/min).
Primarily excreted unchanged in urine (approximately 50-60%) and feces (approximately 20-30%); biliary excretion contributes to fecal elimination.
Renal: 80-90% as unchanged drug; fecal: <1%; biliary: minimal.
