Pain Sensitivity and Pruritus of Peripheral Nerves

Sponsor: Aalborg University

View on ClinicalTrials.gov

Summary

Previous research has demonstrated that itch and pain share several underlying neural pathways and signaling molecules. Understanding these common mechanisms is important for developing more effective therapeutic strategies targeting both sensations. Mepyramine, an antihistamine, has been reported to exert effects on both itch and pain perception. In this study, we aim to investigate these effects using established experimental models of itch and pain. Itch will be induced using histamine, a naturally occurring substance in the human body, and spicules from the plant Mucuna pruriens (cowhage), while electrical stimulation will be used to assess pain-related responses. By combining these experimental approaches, we aim to better understand how mepyramine influences different sensory mechanisms. The overall purpose of this study is to evaluate the effects of mepyramine on experimentally induced itch and pain in healthy volunteers.
