CIPRO HC vs CORDRAN N
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ciprofloxacin inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, preventing DNA replication and transcription; hydrocortisone suppresses inflammation via glucocorticoid receptor activation.
Cordran N contains flurandrenolide, a corticosteroid that exerts anti-inflammatory, antipruritic, and vasoconstrictive actions by inducing phospholipase A2 inhibitory proteins (lipocortins) and modulating gene expression; neomycin is an aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit.
Instill 3 drops into the affected ear(s) twice daily (morning and evening) for 7 days.
Apply sparingly to affected area 2-3 times daily. Use for no longer than 2 weeks.

Ciprofloxacin: 4-6 hours (prolonged to 6-9 hours in elderly or renal impairment). Hydrocortisone: 1-2 hours.
Approximately 1-2 hours. Short half-life consistent with topical use; systemic exposure minimal with proper application.
Ciprofloxacin: ~50-70% excreted renally as unchanged drug, ~15% as metabolites; ~20-30% eliminated via biliary/fecal route. Hydrocortisone: metabolized hepatically, renal excretion of metabolites.
Primarily renal (biliary/fecal minimal). Unchanged drug and glucuronide metabolites excreted in urine.
