Official title

Effect of Beta Blockade on Opioid-Induced Hyperalgesia in Humans

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This research study explores whether a beta-blocker (propranolol) can prevent a person from becoming more sensitive to pain after administration of an opioid (remifentanil). Beta blockers inhibit the sympathetic (fight or flight) response and are often used to treat angina and high blood pressure. In a previous study in human volunteers, the investigators demonstrated an increased sensitivity to pain after a 60-minute infusion of the opioid remifentanil. The goal of this study is to identify a possible inhibitor of this phenomenon.
