[Treatment of chronic pruritus-what is new?]

Chronic pruritus is one of the most common and stressful symptoms in medicine. Therapy remains a great challenge because of the lack of approved therapies. In the recent past a greater understanding of the pathogenesis has enabled the results to be translated into new forms of therapy. The various therapies target a wide range of points in the pruritic cascade-from blockade of intracellular and intercellular signaling pathways in the skin to the modulation of neurotransmission. This article provides a summary of current therapeutic options based on the current S2K guideline and gives an overview about recent developments in antipruritic treatments.
