What is example of partial agonist?

An example of a partial agonist is buprenorphine, which is used in the treatment of opioid addiction and pain management. Unlike full agonists like morphine, buprenorphine binds to opioid receptors but activates them to a lesser degree, producing a milder effect. This property helps reduce withdrawal symptoms and cravings without the same level of euphoria or respiratory depression associated with stronger opioids.
