title: Retapamulin ointment twice daily for 5 days vs oral cephalexin twice daily for 10 days for empiric treatment of secondarily infected traumatic lesions of the skin.
abstract: BACKGROUND
  Retapamulin is a novel, topical antibacterial of the pleuromutilin class in development for the treatment of secondarily infected traumatic lesions of the skin.
  
  
  METHODS
  The efficacy, safety, and tolerability of topical retapamulin ointment, 1% for 5 days twice daily was evaluated in 2 identical, randomized, double-blind, double-dummy, multicenter studies vs oral cephalexin, 500 mg twice daily for 10 days, in 1904 patients with secondarily infected traumatic lesions.
  
  
  RESULTS
  Clinical success rates were 89.5% in protocol-adherent patients receiving retapamulin compared with 91.9% for cephalexin (treatment difference, -2.5% [95% confidence interval, -5.4% to 0.5%]). In patients with Staphylococcus aureus or Streptococcus pyogenes at baseline, clinical success was 89.2% (365/409) for retapamulin and 92.6% (63/68) for cephalexin. Safety and tolerability were similar between treatments. Noncompliance (defined as using or taking <80% of doses) was recorded in 8.0% (51/636) of patients taking cephalexin compared with 0.39% (5/1268) of patients receiving retapamulin.
  
  
  CONCLUSIONS
  Retapamulin offers a novel, effective, and convenient topical treatment for secondarily infected traumatic lesions.
