Researchers at Rice University have revealed a previously unknown function of opioid receptors in the development of the enteric nervous system (ENS), often referred to as the "brain in the gut." This ...

Mapping how Narcan reverses opioid overdose can provide a molecular blueprint for developing more effective drugs against ...

A cross-country research team has identified a promising approach to improving the life-saving function of naloxone (Narcan), a drug used to reverse opioid overdose. The researchers published their ...

Opioids are not stimulants. They are a class of medications primarily used for pain relief. Opioids and stimulants are two different classes of medications that address different needs. Doctors ...
