Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibition of 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 IV or IM divided every 8 to 12 hours; usual adult dose: 15 mg/kg/day
Otic: Instill 3-5 drops into the affected ear(s) 3-4 times daily; for acute otitis externa, a wick may be used initially.

2-3 hours in adults with normal renal function; prolonged to 30-90 hours in ESRD.
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.
Renal: >90% unchanged in urine via glomerular filtration; biliary/fecal: <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.
