New Methodology to End Opioid Crisis?

Researchers at Washington University School of Medicine in St. Louis, USA, have shown they can block receptors in the brain responsible for the emotional components of pain and restore motivation – such findings could lay the groundwork for developing new, less addictive approaches to pain treatment.

“We’re in the midst of an opioid epidemic, and the euphoria associated with opioids is a major driver of opioid dependence,” said senior investigator Jose Moron-Concepcion, PhD, an associate professor of anesthesiology, of neuroscience and of psychiatry.

“By targeting the emotional aspects of pain, we hope to make pain less debilitating so that patients won’t crave the emotional high they get from opioids.”

Opioid painkillers, such as morphine, oxycodone and fentanyl, target receptors on brain cells called mu opioid receptors.

In contrast, the Washington University researchers studied kappa opioid receptors, which operate very differently.

Activating the kappa receptor makes people feel depressed, sad and unmotivated.

So Moron-Concepcion and his colleagues at the Washington University Pain Center thought that by blocking those receptors, they also might dampen the negative emotions associated with pain.
