Dictionary

A mu agonist is a type of drug that activates the mu-opioid receptors in the brain and body. The mu-opioid receptors are responsible for the body’s response to pain and the release of endorphins, which are natural pain-relieving chemicals.

Mu agonists, such as morphine, fentanyl, and oxycodone, bind to these receptors and mimic the effects of endorphins, resulting in pain relief and a sense of well-being. However, they also have a high potential for abuse, dependence, and overdose, and their use is regulated in many countries. Mu agonists are often used in medical settings to relieve severe pain, but their use must be closely monitored to minimize the risk of harm.
