Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminoglycoside antibiotic that irreversibly binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibiting protein synthesis.
Neomycin sulfate is an aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibiting protein synthesis in susceptible bacteria. Polymyxin B sulfate is a polypeptide antibiotic that disrupts bacterial cell membrane integrity by interacting with phospholipids. Hydrocortisone is a corticosteroid that suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating immune cell activity.
15 mg/kg/day IM or IV in divided doses every 12 hours. Maximum daily dose: 1.5 g.
Otic: Instill 3-5 drops into the affected ear(s) 3-4 times daily; for acute otitis externa, a wick may be used initially.

Terminal elimination half-life is 2-4 hours in patients with normal renal function (creatinine clearance >80 mL/min). In anuria, half-life may extend to 50-100 hours, necessitating dose adjustment based on renal function.
Neomycin: 2-3 hours (renal impairment: up to 12-24 hours). Polymyxin B: 4.5-6 hours (prolonged in renal failure). Hydrocortisone: 1.5-2 hours.
Primarily renal excretion via glomerular filtration; approximately 80-90% of administered dose is excreted unchanged in urine within 24 hours. Biliary/fecal excretion is minimal (<1%).
Neomycin is excreted primarily unchanged in feces (97%) after oral administration; absorbed fraction is renally excreted (30-50%). Polymyxin B is renally excreted (60%) with some biliary excretion. Hydrocortisone is metabolized hepatically and excreted renally as conjugates.
