Key Points

This research aims to explore how nitrous oxide modulates the κ-opioid receptor and its role in pain relief.
Utilized nitrous oxide to assess its impact on the κ-opioid receptor activity.
Investigated the interaction between nitrous oxide and the endogenous ligand dynorphin.
Analyzed the antinociceptive effects using appropriate models.
Nitrous oxide significantly enhanced the activity of the κ-opioid receptor.
Observed potent antinociceptive effects in models where dynorphin levels were manipulated.
Results indicate a strong relationship between nitrous oxide and κ-opioid receptor activation, potentially impacting pain management strategies.

Abstract

Nitrous oxide (N₂O) is a widely used inhalational analgesic whose antinociceptive effects depend critically on the κ-opioid receptor (KOR) and its endogenous ligand dynorphin (Dyn). Although N₂O is known to...
