What medications are used in treating people diagnosed with opioid use disorder, and how does each of these work?

What will be an ideal response?

Rapid opioid detoxification uses anesthesia and an opioid antagonist so that withdrawal occurs while the patient is asleep (this is a controversial treatment). Maintenance treatments include substitution with either methadone (long-acting opioid agonist) or buprenorphine (partial opioid agonist). Or, maintenance therapy could be based on naltrexone, a long-acting opioid antagonist that prevents an agonist such as heroin from having any effect on the person.
