Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bacitracin inhibits bacterial cell wall synthesis by dephosphorylating the lipid carrier that transports peptidoglycan precursors across the cell membrane, leading to accumulation of toxic intermediates and cell lysis.
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: Apply thin layer to affected area 1 to 3 times daily; maximum duration of therapy is 1 week.
Apply a thin layer topically to the affected area 1-3 times daily. May be covered with a sterile bandage.

Terminal elimination half-life approximately 2.5–3.5 hours in adults with normal renal function; prolonged in renal impairment (up to 20–30 hours in anuria)
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.
Primarily renal excretion of unchanged drug via glomerular filtration and tubular secretion; >90% of absorbed dose recovered in urine within 24 hours; biliary/fecal elimination minimal (<2%)
Renal excretion accounts for >90% of elimination; primarily glomerular filtration with minimal tubular secretion. Small biliary/fecal elimination (<5%).
