COR-OTICIN vs DERMACORT
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 reduce inflammation and immune response.
1-2 drops in each affected ear twice daily for 7 days.
Apply a thin film to affected area twice daily (every 12 hours) for up to 2 weeks.

Terminal half-life 4-6 hours; prolonged in renal impairment (up to 12-15 hours)
Terminal elimination half-life is approximately 2-3 hours for hydrocortisone, the active component. Due to its short half-life, it requires multiple daily doses for sustained effect.
Renal (60-80% unchanged), fecal/biliary (5-10%)
Primarily hepatic metabolism; metabolites are excreted renally (~75% as glucuronide and sulfate conjugates) and fecally (~25%). Less than 5% of the dose is excreted unchanged in urine.
