BETATREX vs COR-OTICIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Betamethasone is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to reduce inflammation, suppress immune response, and alter connective tissue response.
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).
Adults: 1 gram intravenously every 24 hours. For severe infections, 1 gram every 12 hours may be used.
1-2 drops in each affected ear twice daily for 7 days.

Terminal elimination half-life is 8-12 hours in adults with normal renal function, allowing twice-daily dosing.
Terminal half-life 4-6 hours; prolonged in renal impairment (up to 12-15 hours)
Renal elimination of unchanged drug accounts for approximately 60-70% of the dose; biliary excretion contributes about 20-25%, with the remainder eliminated via feces.
Renal (60-80% unchanged), fecal/biliary (5-10%)
