COR-OTICIN vs DERMATOP
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).
Prednicarbate is a corticosteroid that induces phospholipase A2 inhibitory proteins, collectively called lipocortins, which control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes by inhibiting the release of arachidonic acid from membrane phospholipids.
1-2 drops in each affected ear twice daily for 7 days.
Apply a thin layer to affected skin areas twice daily (morning and evening) for up to 4 weeks. Do not use more than 50 g per week.

Terminal half-life 4-6 hours; prolonged in renal impairment (up to 12-15 hours)
Terminal elimination half-life: approximately 100 hours (range 68-120 hours) following topical administration; prolonged accumulation with chronic use due to high lipophilicity and slow release from skin depot.
Renal (60-80% unchanged), fecal/biliary (5-10%)
Primarily hepatic metabolism with inactive metabolites; <10% excreted renally as unchanged drug; minimal biliary/fecal elimination.
