Curator's Comment: description was created based on several sources, including: https://www.ncbi.nlm.nih.gov/pubmed/4948236 | http://www.rxlist.com/sulfamylon-cream-drug.htm | https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=570ce479-d902-4394-bbae-41dfe16c5485

Mafenide is a sulfonamide-type medication used as an antibiotic. It is indicated for use as an adjunctive topical antimicrobial agent to control bacterial infection when used under moist dressings over meshed autografts on excised burn wounds. Mafenide is not antagonized by pABA, serum, pus or tissue exudates, and there is no correlation between bacterial sensitivities to mafenide and to the sulfonamides. A single case of bone marrow depression and a single case of an acute attack of porphyria have been reported following therapy with mafenide acetate. Fatal hemolytic anemia with disseminated intravascular coagulation, presumably related to a glucose-6-phosphate dehydrogenase deficiency, has been reported following therapy with mafenide acetate. Other adverse reactions are: pain or burning sensation, rash and pruritis, erythema, skin maceration from prolonged wet dressings, facial edema, swelling, hives, blisters, eosinophilia.

Sample Use Guides

In Vivo Use Guide

The grafted area should be covered with one layer of fine mesh gauze. An eight-ply burn dressing should be cut to the size of the graft and wetted with Mafenide 5% solution using an irrigation syringe and/or irrigation tubing until leaking is noticeable.

Route of Administration: Topical

In Vitro Use Guide

The action of mafenide is primarily bacteriostatic and it has been demonstrated to be active in vitro in concentrations of 5 mg/ml or less against a variety of Gram-positive and Gram-negative organisms. Ps. aeruginosa is the most sensitive; with 32 of 41 strains the minimum inhibitory concentration (MIC) was 0.2 to 1 mg/ml and with the remaining 9 strains the MIC was 2 to 5 mg/ml. In other studies the mean MIC was 0.31 mg/ml (range 0.075 to 5 mg/ml) for 55 strains of Ps. aeruginosa isolated from clinical material (Thompson et al., 1969) and 1.25 mg/ml for 7 strains of Ps. Aeruginosa.
