Order:: https://cosmodix.com/adhd/suboxone/ Subutex (buprenorphine) is a prescription medication used to treat opioid addiction. It is a partial opioid agonist, which means that it binds to the same receptors in the brain as opioids but does not produce the same euphoric effects. This makes it a safer and more effective option for treating opioid addiction than full opioid agonists, such as methadone or heroin.
