The Future of Atopic Dermatitis Treatment.

In recent years, there has been a growing movement towards the use of targeted therapies in treating of atopic dermatitis (AD), parallel to that which has occurred in psoriasis. Among the systemic medications being studied are subcutaneous or intravenously administered biologic drugs targeting specific molecules such as IL4, IL13, IL17, and IgE. Non-biologic oral therapies are also being developed for AD and include small molecule drugs targeting phosphodiesterase type IV (PDE4) inhibition or Janus Kinase (JAK) inhibition. Numerous topical formulations are also being studied, with some formulations that are novel therapies that act as topical biologic or small molecule agents with mechanisms of action similar to systemic treatments. Others are being developed as skin barrier repair therapies for reduction of AD symptoms. This chapter will discuss new advances in AD treatment from medications in the initial stages of development to those nearing FDA approval.
