COR-OTICIN vs DERMATOP E EMOLLIENT
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 binds to the glucocorticoid receptor, leading to inhibition of phospholipase A2, decreased release of arachidonic acid, and reduced synthesis of prostaglandins, leukotrienes, and other inflammatory mediators.
1-2 drops in each affected ear twice daily for 7 days.
Apply a thin layer topically to affected areas twice daily. Maximum 3-week course.

Terminal half-life 4-6 hours; prolonged in renal impairment (up to 12-15 hours)
Terminal elimination half-life: 18-36 hours. Clinically, once-daily dosing maintains therapeutic effect.
Renal (60-80% unchanged), fecal/biliary (5-10%)
Predominantly hepatic metabolism; renal excretion of metabolites <5% unchanged; biliary/fecal excretion minimal.
