Prurigo nodularis (PN) is a chronic, recalcitrant inflammatory skin condition characterized by the presence of pruritic nodules. The exact pathogenesis of the disease is unknown, although immune and neural dysregulation are indicated in driving the itchscratch cycle. Specifically, interleukin-4 and interleukin-31 pathways have been recently implicated in transmission of the pruritic sensation. There are currently no US FDA-approved targeted therapies for the treatment of PN. This article aims to review our present understanding of the disease pathogenesis and treatments, with a focus on emerging therapeutics. Specifically, this article explores the developing use of monoclonal antibodies nemolizumab and dupilumab, opioid receptor modulation and cannabinoids as potential treatments for PN.
