Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Erythromycin is a macrolide antibiotic that binds to the 50S subunit of the bacterial ribosome, inhibiting protein synthesis by blocking the translocation step. It also has anti-inflammatory and immunomodulatory effects, including inhibition of neutrophil chemotaxis and modulation of cytokine production.
Neosporin is a combination of three antibiotics: neomycin (aminoglycoside) inhibits bacterial protein synthesis by binding to 30S ribosomal subunit; polymyxin B (polymyxin) disrupts bacterial cell membrane integrity; bacitracin (polypeptide) inhibits bacterial cell wall synthesis by interfering with dephosphorylation of the lipid carrier.
Topical application of a thin layer to affected area twice daily; oral administration not applicable.
Apply a thin layer topically to the affected area 1-3 times daily. May be covered with a sterile bandage.

Terminal elimination half-life: 1.5–2.0 hours in adults with normal renal function, prolonged in renal impairment (up to 6–8 hours with GFR <30 mL/min).
Variable based on severity of renal impairment. Normal renal function: 2-3 hours for neomycin (main component); polymyxin B: 4-6 hours. In anuria: half-life extends to 72-96 hours for neomycin.
Almost entirely renal (90-95% as unchanged drug via glomerular filtration and tubular secretion), with less than 5% fecal or biliary elimination.
Renal excretion accounts for >90% of elimination; primarily glomerular filtration with minimal tubular secretion. Small biliary/fecal elimination (<5%).
