COR-OTICIN vs DIPROLENE AF
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).
Betamethasone dipropionate is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and inhibition of phospholipase A2, thereby reducing the release of arachidonic acid and subsequent production of prostaglandins and leukotrienes. This results in anti-inflammatory, antipruritic, and vasoconstrictive effects.
1-2 drops in each affected ear twice daily for 7 days.
Apply a thin film to affected skin areas twice daily. Maximum 45 g per week. Not to exceed 2 consecutive weeks of treatment.

Terminal half-life 4-6 hours; prolonged in renal impairment (up to 12-15 hours)
Approximately 2.5-3 hours (terminal half-life) for betamethasone dipropionate (active moiety); clinical effects persist beyond half-life due to receptor-mediated activity.
Renal (60-80% unchanged), fecal/biliary (5-10%)
Primarily hepatic metabolism; inactive metabolites excreted renally (approximately 80-85% as metabolites in urine) and fecally (approximately 15-20%).
