Abstract

Introduction: Chronic pruritus is a common symptom that arises from both dermatologic and non-dermatologic conditions including chronic kidney disease, cholestasis, lymphoma and neuropathy. Over the past decade, research has elucidated many of the receptors, neuropeptides and cytokines involved in itch sensation and transmission. In addition, the first biomarker for cholestatic itch has been discovered. These findings have led to the development of a host of novel antipruritic medications, both on the market and in the pipeline. Areas covered: A summary of new and emerging treatments for pruritus, as well as possible targets for future therapeutic development is provided. Expert opinion: At present, there is no universally effective treatment available for all types of chronic pruritus. A combination of topical and systemic therapies addressing peripheral mediators, and a top-down approach targeting the brain and spinal cord, seems preferable to a single agent approach. Neural hypersensitization plays a significant role in many forms of chronic pruritus and may be downregulated by new treatments. In addition, specific neuropeptides are now targeted by novel antipruritic therapies. Furthermore, targeted biologic agents are anticipated to play a significant role in treating pruritus of inflammatory origin.
