Retapamulin: a review of its use in the management of impetigo and other uncomplicated superficial skin infections.

Abstract

Topical retapamulin (Altabax, Altargo) is the first pleuromutilin antibacterial approved for the treatment of uncomplicated superficial skin infections caused by Staphylococcus aureus (excluding meticillin-resistant S. aureus [MRSA]) and Streptococcus pyogenes in patients aged > or = 9 months. In the EU, retapamulin is indicated for use in patients with impetigo or with infected small lacerations, abrasions or sutured wounds (without abscesses); in the US, it is indicated for use in patients with impetigo. Retapamulin has a novel site of action on bacterial ribosomes. In clinical trials in patients with impetigo, topical retapamulin 1% ointment twice daily for 5 days (the approved regimen) was superior to placebo; treatment with retapamulin was noninferior to that with topical fusidic acid. In patients with secondarily infected traumatic lesions, treatment with retapamulin was noninferior to that with oral cefalexin, although the efficacy of retapamulin was reduced in patients with MRSA infections or superficial abscesses. Retapamulin was well tolerated in both paediatric and adult patients, and the majority of adverse events were of mild to moderate severity. Thus, the introduction of topical retapamulin 1% ointment extends the treatment options available in the management of impetigo and uncomplicated secondarily infected traumatic lesions.
