Opioid use disorder is a chronic, relapsing disease with physical and psychiatric components. It is associated with economic hardship, social isolation, incarceration, increased rates of blood-borne infections such as HIV and viral hepatitis, adverse pregnancy outcomes, and increased mortality. According to the NIH, there were 80,411 deaths involving an opioid in the US in 2021, more than in any previous year. Several guidelines on the management of opioid use disorder are available; all recommend maintenance pharmacotherapy as the standard of care.

The FDA has approved a subcutaneously injected, extended-release formulation of the mu-opioid receptor partial agonist and kappa-opioid receptor antagonist buprenorphine (Brixadi – Braeburn) for once-weekly or once-monthly treatment of moderate to severe opioid use disorder. Brixadi is the second subcutaneously injected buprenorphine formulation to be approved in the US; Sublocade, which is administered once monthly, was the first. Buprenorphine is also available for treatment of opioid use disorder in sublingual formulations with and without the opioid antagonist naloxone.
