Mupirocin acts by inhibiting bacterial protein synthesis, by binding with isoleucyl-tRNA synthetase enzyme, thus preventing the incorporation of isoleucine into protein chains. The use in extensive area or in patients with burns aren’t recommended, because of the risk of nephrotoxicity and absorption of the drug’s vehicle, polyethylene glycol, especially in patients with renal insufficiency. It is less effective in traumatic lesions and those with abscess formation usually caused by anaerobic bacteria and MRSA.

Toxins are the greatest virulence factor of S. Therefore, concern about MRSA in community-acquired infections, should be greater in the presence of nips and abscesses and smaller in impetigo. In the United States there is already a formulation of mupirocin ointment without polyethylene glycol.


Neomycin sulfate is active mainly against aerobic Gram-negative bacteria Escherichia coli, Enterobacter aerogenes, Klebsiella pneumoniae, Proteus vulgaris. Sensitized patients may cross-react when exposed to other topical or systemic aminoglycosides. Bullous impetigo occurs most commonly in impetivo regions such as the diaper area, axillae and neck, although any cutaneous area can be affected, including palms and soles Figures 1 and 2.

Unique approaches for the topical treatment and prevention of cutaneous infections: Bacterial resistance and impetigo treatment trends: There is strong evidence on the imletigo, or at least the equivalence, of topical antibiotics compared to oral antibiotics in the treatment of localized impetigo.

Its actions against most Gram-positive bacteria are limited. Topical agents for impetigo therapy are reviewed. It is also effective, to a lesser extent, against Streptococcus and Propionibacterium acnes. Systemic absorption is minimal and the little that is absorbed is rapidly converted to inactive metabolite, hence the reason why there are not oral or parenteral formulations available. As side effects, contact dermatitis and more rarely, anaphylactic shock have been reported.

It is effective against S. Regulatory mechanism for exfoliative toxin production in Staphylococcus aureus.

It is considered safe and effective in patients over two-months old. Staphylococcal infections are present in all age groups. The isolation of streptococci of groups other than A can mean a secondary infection of preexisting lesions or colonization on cutaneous surface. Rheumatic fever can be a complication of streptococcal pharyngitis or tonsillitis, but it does not occur after skin infections. Mupirocin in the treatment of impetigo. Luciana Baptista Pereira Av. Bullous impetigo and scalded skin syndrome, caused by staphylococcal toxins and toxic shock syndrome, caused by staphylococcal or streptococcal toxins are examples of toxin-mediated diseases.

In Brazil mapolloso is available as an ointment and in combination with neomycin.
