Some researchers are focusing on new treatments for atopic dermatitis, including biologic agents, fatty acid supplements, and new forms of phototherapy. For example, they are studying how ultraviolet light affects the skin's immune system in healthy and diseased skin. They are also investigating biologic agents, including several aimed at modifying the response of the immune system. A biologic agent is a new type of drug based on molecules that occur naturally in the body. One promising treatment is the use of thymopentin to reestablish balance in the immune system.

Researchers also continue to look for drugs that suppress the immune system. In this regard, they are studying the effectiveness of cyclosporine A. Clinical trials are underway with another drug called FK506, which is applied to the skin rather than taken orally. Also, anti-inflammatory drugs have been developed that affect multiple cells and cell functions, and may prove to be an effective alternative to corticosteroids in the treatment of atopic dermatitis.
