Buprenorphine serves as what type of agent for opiate addiction?

Buprenorphine works as a partial agonist at the mu-opioid receptor, providing some opioid effect, but with a ceiling that limits how strong that effect can be. It also acts as an antagonist at other opioid receptor types (notably kappa) and, because it binds very tightly to mu receptors, it can block other opioids from activating those receptors. This combination—producing some activation while blocking others—makes it an agonist-antagonist (a mixed opioid receptor agent). It’s not a pure antagonist, since it does activate mu receptors to a degree, and it’s not a pure agonist, since its maximum effect is limited and it can block other opioids. It’s also not an antipsychotic.
