Norbuprenorphine is the primary active metabolite of buprenorphine. Norbuprenorphine acts as a μ-opioid, δ-opioid, and nociceptin receptor full agonist,[1][2] as well as a κ-opioid receptor partial agonist.[2] Norbuprenorphine crosses the blood-brain-barrier similarly to buprenorphine and likely contributes to its effects.[3]
