Suboxone is classified as an opioid partial agonist. It is both an opiate and an opiate blocker.
Suboxone works by binding itself to the receptors in the brain to which opioids attach.
When opioids attach to the receptors, they produce that euphoric or “high” feeling. But with suboxone, these receptors are fooled into thinking they are being satisfied, but without producing that euphoric feeling.
