Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, causing misreading of mRNA and production of nonfunctional proteins.
Combination antibiotic and corticosteroid: Neomycin, polymyxin B, and bacitracin are antibiotics that inhibit bacterial protein synthesis, disrupt cell membrane permeability, and inhibit cell wall synthesis, respectively; hydrocortisone is a corticosteroid that suppresses inflammatory responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis.
15-25 mg/kg/day orally in 4 divided doses for hepatic coma; 50 mg/kg/day orally in 4 divided doses for infectious diarrhea, max 4 g/day.
Apply 3-4 times daily to affected area as a thin layer. Topical route. Frequency: every 6-12 hours.

2-3 hours (serum half-life of absorbed fraction); clinically negligible due to minimal systemic absorption
Neomycin: 2-3h (systemic, IM); Bacitracin: 1.5h (systemic, IM); Polymyxin B: 6h (systemic, IV); Hydrocortisone: 1.5-2h (systemic). Topical: not applicable due to minimal absorption.
Primarily unchanged in feces (~90%); small amount absorbed is excreted renally as unchanged drug (~1%)
Renal: Neomycin (<1% absorbed, remainder fecal), Bacitracin (10-40% renal if absorbed, negligible), Polymyxin B (60% renal over 24h if absorbed), Hydrocortisone (metabolized, <1% unchanged renal; fecal for unabsorbed). Topical: negligible systemic absorption; fecal for unabsorbed.
