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 inhibiting bacterial protein synthesis.
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.
3-6 mg/kg/day IV in 2-3 divided doses every 8-12 hours; adjust based on serum levels and renal function.
Apply 3-4 times daily to affected area as a thin layer. Topical route. Frequency: every 6-12 hours.

Terminal elimination half-life is 2-3 hours in patients with normal renal function. Prolonged to 24-48 hours in anuria. Clinical context: Dosing interval adjustment required in renal impairment to avoid toxicity.
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.
Renal excretion of unchanged drug accounts for >90% of elimination. Approximately 10% is excreted in bile.
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.
