Mechanism of action

Diacetylmorphine is a semi-synthetic opioid derived from morphine. It crosses the blood-brain barrier more readily than morphine due to its lipophilicity, and is rapidly deacetylated to morphine and 6-monoacetylmorphine in the body. It acts as an agonist at opioid receptors, particularly mu receptors, producing potent analgesic and psychoactive effects. In the context of this Phase 3 trial at UBC, it is being investigated as a pharmaceutical-grade oral formulation for opioid use disorder or chronic pain management in a controlled medical setting.
