CIPROFLOXACIN HYDROCHLORIDE AND HYDROCORTISONE vs QUIXIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ciprofloxacin is a fluoroquinolone antibiotic that inhibits bacterial DNA gyrase and topoisomerase IV, preventing DNA replication and transcription. Hydrocortisone is a corticosteroid that suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis.
Quixin (levofloxacin) is a fluoroquinolone antibiotic that inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, thereby interfering with DNA replication, transcription, repair, and recombination.
Otic suspension: 3 drops (0.25 mL) into affected ear(s) twice daily for 7 days. Each drop contains ciprofloxacin HCl (equivalent to 0.2 mg ciprofloxacin base) and hydrocortisone 1 mg.
One to two drops in affected eye(s) every 2 hours while awake, up to 8 times daily for 7-14 days.

Ciprofloxacin: ~4-5 hours (normal renal function); prolonged to 8-10 hours in severe renal impairment (CrCl <30 mL/min). Hydrocortisone: ~1.5-2 hours.
Terminal elimination half-life: 6–8 hours in adults with normal renal function; prolonged in renal impairment (up to 20 hours if CrCl <30 mL/min).
Ciprofloxacin: ~50-70% excreted unchanged in urine via glomerular filtration and tubular secretion; ~15-20% as metabolites; ~20-30% in feces via biliary excretion and transintestinal secretion. Hydrocortisone: metabolized in liver, metabolites excreted renally.
Renal (approximately 70% unchanged in urine); biliary/fecal (~30%, partly as metabolites and unchanged drug).
