Mechanism of action

Buprenorphine acts as a partial agonist at the mu-opioid receptor, producing analgesia and euphoria at lower doses while exhibiting a ceiling effect on respiratory depression at higher doses. The subcutaneous injectable formulation provides sustained drug delivery for opioid use disorder treatment and pain management. Its high receptor binding affinity and long half-life make it suitable for maintenance therapy with reduced abuse potential compared to full mu-opioid agonists.
