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, thereby preventing DNA replication and transcription.
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.
500 mg to 1000 mg orally once daily for 7 to 14 days; extended-release tablet must be swallowed whole and administered with food.
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.

Terminal elimination half-life is approximately 10-12 hours in patients with normal renal function, allowing twice-daily dosing; due to extended-release formulation, ciprofloxacin is released over 24 hours.
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.
Renal excretion of unchanged drug accounts for approximately 40-50% of the dose; hepatic metabolism (glucuronidation, sulfation) produces active metabolites, and biliary/fecal elimination (via feces) accounts for 20-35% of the dose.
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.
