For decades, opioids have been the blunt instrument of modern pain care, powerful enough to quiet severe suffering yet risky ...

New research reveals previously unknown ways opioid receptors can function, opening the door to safer pain treatments.

This confocal microscope image shows midbrain neurons (red) co-expressing the mu-opioid receptor (Oprm1, white) and cannabinoid receptor 1 (Cnr1, green). The interaction of these two reward pathways ...

Distinct brain circuits drive two key components of addiction to the synthetic opioid drug fentanyl, according to a new finding published in Nature (2024, DOI: 10.1038/s41586-024-07440-x). The ...

Having a pill that alleviates chronic pain without adverse side effects or the risk of addiction remains an unmet pharmaceutical need for millions of people currently using traditional opioid drugs.

Researchers at USF Health have discovered a new way opioid receptors can work that may lead to safer pain medications. Their findings show that certain experimental compounds can amplify pain relief ...

University of Florida scientists have helped identify a novel drug compound that selectively activates pain-altering receptors in the body, offering a potentially safer alternative to conventional ...

Scientists have known for decades that opioids relieve pain by binding to molecular switches in the brain called mu-opioid (pronounced "mew-opioid") receptors. What they didn't know - until now - was ...
