Components of Treatment for Opioid use Disorder
Pharmacotherapy
• Full opioid agonist: methadone
• Partial opioid agonist: buprenorphine
• Opioid antagonist: naltrexone
Psychosocial/behavioral
• Levels of care – Outpatient, IOP/PHP,
residential
• Modalities – CBT, MI/MET, CM, TSF
Peer-based Recovery Support
• AA, NA, SMART recovery
• Recovery coaches

Similar to Management of Diabetes
• No cure
• Goal is euglycemia and prevention of acute and chronic complications
• Individualized treatment plans and targets
• Treatment includes: – Medication
– Lifestyle changes
– Regular monitoring for complications
– Behavioral support

Pharmacology of Treatments
Antagonist (naltrexone)
![Page 6: Treatment of Opioid Use Disorder - media-ns.mghcpd.org.s3 ...media-ns.mghcpd.org.s3.amazonaws.com/sud2017/2017...•Initiating buprenorphine vs detox: –Bupe: 72.2% enter into treatment](https://reader034.fdocuments.in/reader034/viewer/2022042314/5f02a4d27e708231d4054aa5/html5/thumbnails/6.jpg)
www.mghcme.org
Details of Treatment
• Agonist treatment consists of daily methadone or buprenorphine – Stable level of opioid effect is experienced as neither
intoxication nor withdrawal, but as “normal” – Requires waivered prescriber or opioid treatment program
• The aims of agonist maintenance treatment include: – reduction or cessation of illicit opioids and associated risks – improvement in psychological and physical health
• Antagonist treatment consists of once monthly injection – Anyone can prescribe naltrexone

www.mghcme.org
Detoxification versus Maintenance
• Pharmacological management: – tapering with methadone or buprenorphine
– sudden opioid cessation and use of alpha-2 adrenergic agonists to relieve symptoms
• Most patients resume opioid use within six months of detoxification
• Detoxification alone should not be promoted as effective treatment

Behavioral Treatments
• Evidence-based interventions either skills-based or utilize incentives
• Goal to engage people in treatment, change attitudes and behaviors related to substance use, and increase skills to manage stress & cravings
• Cognitive-behavioral therapy: – skills to manage cravings, identify and avoid high risk situations, utilize
self-monitoring
• Motivational Enhancement Therapy: – resolve ambivalence through eliciting reasons for change,
strengthening motivation, and developing a plan for change
• Contingency Management: – rewards for engaging in treatment or not using substances

Agonist versus Antagonist Treatment
• Oral naltrexone ineffective
• Extended-release naltrexone more effective than placebo
• No direct comparisons between extended-release naltrexone and methadone or buprenorphine
• Retention rates worse with naltrexone

WHO Guidelines
• “Of all the treatments, opioid agonist maintenance treatment, combined with psychosocial assistance is most effective… psychosocial services should be made available to all patients, although those who do not take up the offer should not be denied effective pharmacological treatment.”
