Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Sulfamylon (mafenide acetate) is a synthetic sulfonamide that exerts bacteriostatic activity against a wide range of Gram-negative and Gram-positive organisms. It acts by inhibiting the enzyme dihydropteroate synthase, which is involved in folate synthesis, thereby blocking bacterial DNA replication. Additionally, it may be bactericidal at high concentrations via inhibition of cell wall synthesis.
Bactericidal; inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs) and disrupting peptidoglycan cross-linking.
Topical: Apply a thin layer to the wound once or twice daily. Maximum coverage area should not exceed body surface area of 20%.
500 mg orally 4 times daily for 10-14 days (or 1 g orally 4 times daily for severe infections).

The terminal elimination half-life is approximately 7-8 hours in patients with normal renal function. In renal impairment, half-life may be prolonged, requiring dosing adjustments.
8 hours (terminal) — extends in renal impairment (up to 24 hours in CrCl <30 mL/min); requires dose adjustment
Primarily renal excretion as unchanged drug and its metabolite; approximately 87% of a dose is recovered in urine within 24 hours as sulfacetamide and its deacetylated metabolite, with about 10% as unchanged drug. Less than 2% is excreted in feces.
Renal: 70% (unchanged); biliary/fecal: 20%; minor hepatic metabolism (<10%)
