Mechanism of action

SUBLOCADE delivers buprenorphine, a partial mu-opioid receptor agonist, via a subdermal implant that releases the drug over approximately one month. This sustained-release formulation reduces withdrawal symptoms and cravings in patients with opioid use disorder while minimizing the abuse potential associated with daily dosing. The extended-release mechanism improves medication adherence and reduces the burden of daily clinic visits.
