How does buprenorphine work?
Buprenorphine works by binding to opioid receptors in the brain, but it does so with a lower level of activity than full opioid agonists [1]. This partial agonism can help reduce cravings and withdrawal symptoms associated with opioid use disorder without producing the same degree of euphoria or respiratory depression as full agonists [1]. The addition of naloxone, when taken as prescribed, deters injection and nasal abuse of the medication by blocking the effects of buprenorphine [1].
