Researchers at Scripps Research have redesigned fentanyl at the molecular level, challenging decades-old assumptions about opioid chemistry.

Drugs that target opioid receptors sometimes have severe side effects. Thousands of people around the world die every day from overdoses involving opioids such as fentanyl. Researchers have taken a ...

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 ...

However, the opioid pathway, a heavily studied physiologic pathway inextricably intertwined with behaviour and reward, rarely receives attention within psychiatric practice. Although the opioid system ...

Visual Abstract. Whole-body [11C] carfentanil PET imaging at baseline (left side of panel) and then following naloxone (middle panel) shows μ-opioid receptor (MOR) in the brain (color) and throughout ...

Fentanyl is one of the most effective drugs for managing severe pain, yet it carries substantial risks of addiction and ...

An Intra-Cellular Therapies Inc. patent describes new 5-HT2A, μ-opioid, and dopamine D1 and D2 receptor ligands reported to be useful for the treatment of neurological disorders.

Brain volume and function are altered in individuals with opioid use disorder, a new Yale study finds. Using magnetic resonance imaging (MRI) and functional MRI (fMRI), researchers observed the ...

Naloxone (also known as Narcan, the commonly used drug to treat narcotic overdoses) has greater binding to opioid receptors in women's brains than in men's brains, according to new research published ...
