Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mupirocin binds to isoleucyl-tRNA synthetase, inhibiting bacterial protein synthesis.
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.
Apply a thin layer to affected area twice daily for 10 days. For perioral dermatitis, apply once daily.
Apply a thin layer topically to the affected area 1-3 times daily. May be covered with a sterile bandage.

8-10 minutes in serum; prolonged to 15-20 minutes in patients with renal impairment. Clinical context: Rapidly cleared, infrequent dosing intervals (e.g., every 20 minutes during procedure).
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 excreted unchanged in urine via glomerular filtration and tubular secretion (85-90% renal); minor biliary/fecal elimination (<5%).
Renal excretion accounts for >90% of elimination; primarily glomerular filtration with minimal tubular secretion. Small biliary/fecal elimination (<5%).
