Abrocitinib in atopic dermatitis: review of the current literature and clinical trials

Atopic dermatitis (AD) is an inflammatory chronic-relapsing skin disease affecting approximately 15% to 20% of children and 10% of adults in industrialized countries. Both loss of epidermal barrier permeability and immune dysregulation seem to be the most important actors in AD pathogenesis. Several studies have demonstrated the role of Janus kinase (JAK) enzymes in AD pathogenesis suggesting oral and topical JAK inhibitors as new emerging therapies for AD. Among the JAK inhibitors, abrocitinib is an oral JAK1-selective inhibitor. The aim of this study is reviewing current literature about the efficacy and safety of abrocitinib in AD. The literature search was carried out considering the main search engines relating to medical literature and clinical trials. The efficacy and safety of abrocitinib have been confirmed in several studies suggesting this drug as a valuable treatment for moderate to severe AD.
