MAFENIDE ACETATE vs SODIUM SULAMYD
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Sodium sulfacetamide is a sulfonamide antibiotic that inhibits bacterial dihydropteroate synthase, blocking folate synthesis.
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.
1-2 drops of 10% or 15% solution into affected eye(s) every 2-3 hours initially, tapered as infection resolves; ophthalmic ointment: apply 0.5-inch ribbon into conjunctival sac every 3-4 hours and at bedtime.

Approximately 45 minutes (range 30-60 minutes) for the parent compound; the metabolite p-CBS has a longer half-life of about 4 hours.
7-13 hours (prolonged in renal impairment; in anuria up to 22-50 hours)
Renal: approximately 80% excreted unchanged in urine; the remainder is metabolized to p-carboxybenzene sulfonamide (p-CBS) which is also renally excreted.
Renal excretion of unchanged drug (approximately 70-100%) via glomerular filtration and tubular secretion; minor biliary/fecal elimination (<5%)
