Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mupirocin binds to isoleucyl-tRNA synthetase, inhibiting bacterial protein synthesis.
Mafenide acetate is a sulfonamide antibiotic that inhibits bacterial folic acid synthesis by competitively antagonizing para-aminobenzoic acid (PABA), thereby preventing bacterial growth. It has broad-spectrum activity against gram-negative and gram-positive organisms, including Pseudomonas aeruginosa.
Apply a thin layer to affected area twice daily for 10 days. For perioral dermatitis, apply once daily.
Apply topically as a thin layer to affected areas once or twice daily. The dosage form is an 11.1% cream or solution. The cream is applied using a sterile gloved hand; the solution is applied with a sterile spray or brush.

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).
Approximately 45 minutes (range 30-60 minutes) for the parent compound; the metabolite p-CBS has a longer half-life of about 4 hours.
Primarily excreted unchanged in urine via glomerular filtration and tubular secretion (85-90% renal); minor biliary/fecal elimination (<5%).
Renal: approximately 80% excreted unchanged in urine; the remainder is metabolized to p-carboxybenzene sulfonamide (p-CBS) which is also renally excreted.
