ABSTRACT

Uremic pruritus, a severe complication in patients with chronic kidney disease, is associated with a high prevalence. It can cause depression and sleep disorders, and seriously affect the quality of life and the social relations of patients. Recently, there is growing evidence showing that κ-opioid receptor agonists, including nalfurafine, difelikefalin, and nalbuphine, can effectively and safely reduce itching symptoms in patients with refractory uremic pruritus. Herein, we reviewed the epidemiology, pathogenesis, clinical symptoms, and treatment strategies of uremic pruritus, and summarized in detail the progress in clinical research on the use of κ-opioid receptor agonists, including nalfurafine, difelikefalin, and nalbuphine, in the management of patients with uremic pruritus.
