COR-OTICIN vs CORDRAN N
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).
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.
1-2 drops in each affected ear twice daily for 7 days.
Apply sparingly to affected area 2-3 times daily. Use for no longer than 2 weeks.

Terminal half-life 4-6 hours; prolonged in renal impairment (up to 12-15 hours)
Approximately 1-2 hours. Short half-life consistent with topical use; systemic exposure minimal with proper application.
Renal (60-80% unchanged), fecal/biliary (5-10%)
Primarily renal (biliary/fecal minimal). Unchanged drug and glucuronide metabolites excreted in urine.
