Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminoglycoside antibiotic that binds to the 30S ribosomal subunit, inhibiting bacterial protein synthesis and causing mRNA misreading.
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 mg/kg/day IM or IV divided every 8-12 hours (not to exceed 1.5 g/day)
Apply 3-4 times daily to affected area as a thin layer. Topical route. Frequency: every 6-12 hours.

2-3 hours (normal renal function); prolonged to 30-50 hours in anuria; clinically significant accumulation in renal impairment requires monitoring
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: 80-100% as unchanged drug via glomerular filtration; fecal: <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.
