A 34-yeаr-оld mаn with а histоry оf opioid use disorder is preparing to begin relapse-prevention therapy following a successful detoxification. During the visit, he admits that his strongest fear is “giving in when I get cravings or when someone offers me something.” He explains that in the past, even small slips would “send me straight back into using.” He is highly motivated for recovery and asks whether the new medication will “take away the high” if he encounters opioids again. The clinician explains that the medication he is about to start binds to opioid receptors with high affinity but produces no intrinsic activity, thereby preventing opioids from triggering their usual reinforcing effects. This mechanism reduces the likelihood of relapse by making previously rewarding drugs feel ineffective and unrewarding. Which explanation best reflects the mechanism of action being described?
