Brain areas activated by itch-relieving drug identified

Brain areas that respond to reward and pleasure are linked to the ability of the drug butorphanol to relieve itch, according to new research. The findings point to the involvement of the brain’s opioid receptors — known for their roles in pain, reward, and addiction — in itch relief, potentially opening up new avenues to the development of treatments for chronic itch.
