COR-OTICIN vs CORDRAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
COR-OTICIN is a combination product containing hydrocortisone (a corticosteroid with anti-inflammatory and immunosuppressive properties) and neomycin (an aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit) and polymyxin B (a polymyxin antibiotic that disrupts bacterial cell membrane permeability).
Corticosteroid that binds to glucocorticoid receptors, modulating gene expression to induce anti-inflammatory, antipruritic, and vasoconstrictive effects.
1-2 drops in each affected ear twice daily for 7 days.
Apply a thin layer to the affected skin areas once or twice daily. For CORDRAN Tape, apply tape to affected area once every 12 to 24 hours.

Terminal half-life 4-6 hours; prolonged in renal impairment (up to 12-15 hours)
Terminal half-life is approximately 7.5 hours (range 6-10 hours) in adults with normal hepatic function. This supports twined-daily dosing for dermatological indications.
Renal (60-80% unchanged), fecal/biliary (5-10%)
Primarily hepatic metabolism; metabolites excreted in urine and feces. Renal excretion of unchanged drug is negligible (<5%). Biliary/fecal excretion accounts for ~20% of metabolites.
