Purpose of review This review aims to provide a summary of current knowledge on new topical and oral non-biological therapies recently approved for Atopic Dermatitis (AD) treatment. Recent findings The immense research carried out in the last decade has focused on understanding the molecular basis underlying AD and has allowed the development of new targeted drugs. Despite several biologic therapies are approved or in development, other non-biologic targeted therapies (small molecules) have emerged, such as the Janus kinase (JAK) inhibitors baricitinib, upadacitinib and abrocitinib, expanding the range of therapeutic options. Based on recent available data from head-to-head comparisons and meta-analysis studies, JAK inhibitors showed a faster onset of action and slightly higher efficacy at 16 weeks compared with biologic agents. Concerning topical treatment, presently, corticosteroids and calcineurin inhibitors are the main therapeutic options, but are not recommended for long-term management due to potential safety issues. Currently, two topical JAK inhibitors (ruxolitinib and delgocitinib) and one phosphodiesterase 4 (PDE4) inhibitor (difamilast) are approved and have shown good efficacy results and a favorable safety profile. Summary These new drugs (systemic and topical) are needed to increase the success of AD treatment, particularly for patients who do not or no longer respond to treatment.
