Opioid agonists are substances that activate opioid receptors in the central and peripheral nervous systems. They have several uses, from pain management to treating opioid use disorder. You have ...

New research undertaken by American and Chinese researchers may pave the way for safer opioid painkillers, thanks to the use of cryo-electron microscopy (cryo-EM) to examine the detailed structures of ...

A clinical trial of an experimental drug for treatment-resistant major depression finds that modulation of the endogenous opioid system may improve the effectiveness of drugs that target the action of ...

Everyone knows that stubbing your toe hurts. What makes it stop hurting is the body's main pain-blocking process - the natural production of opioids. Cognitive-based approaches found to reduce pain, ...

Given how profound an influence opioids have on the world – for better or worse – scientists know surprisingly little about how these drugs actually work. A recent study led by researchers from ...

Opioids slot into opioid receptors and activate them. This sends signals to your brain to relieve pain and promote pleasure. Both endogenous opioids, which your body naturally produces, and exogenous ...
