Review of mupirocin ointment in the treatment of impetigo.

The introduction of mupirocin ointment gives the pediatrician a reliable topical alternative to oral antibiotic therapy for group A streptococcal and staphylococcal impetigo. It is as effective as oral antibiotics and is associated with fewer adverse effects. In superficial skin infections that are not widespread, mupirocin ointment offers several advantages. It is highly active against the most frequent skin pathogens, even those resistant to other antibiotics, and the topical route of administration allows delivery of high drug concentrations to the site of infection.
