Abstract
BACKGROUND: Ingenol mebutate is a newly approved topical field therapy for actinic keratosis (AK). It has a dual mechanism of action comprising of a rapid induction of necrosis that specifically targets dysplastic cells, as well as neutrophil-mediated immunostimulatory effects. Such a dual mechanism allows for this agent to clear AK lesions in as little as two to three daily applications, thus providing for improved treatment outcomes and patient satisfaction. REVIEW: Given that this is a new dermatologic therapy, this review summarizes the key literature surrounding this agent. This review covers the indications for use, mechanisms of action, method of administration, efficacy and safety profile and important drug interactions of ingenol mebutate. CONCLUSIONS: Ingenol mebutate should be considered a highly relevant field therapy for AK and the prevention of progression to squamous cell carcinoma.
