New treatment option for Analgesia
Official title RM1 Project 1 - tAN Naloxone
ClinicalTrials.gov ID: NCT05490134
What this study is testing
What is Naloxone?
Naloxone is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for analgesia.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This two-visit, randomized, double-blind, sham-controlled trial, uses a novel naloxone blockade model in 136 individuals to determine whether the analgesic effects of a 30-minute transcutaneous auricular neurostimulation (tAN) intervention are mediated through a release of endogenous opioids. Analgesic effects of four various stimulation interventions will be measured (auricular vagus, auricular trigeminal, combination, or sham) while varying the type of intravenous (IV) infusion (either naloxone or saline) a participant is administered to determine whether the analgesic effects are mitigated by pharmacological opioid receptor blockade.
