What is the recommended treatment for patients with opioid use disorder using Suboxone (buprenorphine)?

Recommended Treatment for Opioid Use Disorder Using Suboxone (Buprenorphine)

Medication-assisted treatment with Suboxone (buprenorphine/naloxone) is the first-line treatment for opioid use disorder, as it significantly reduces mortality, opioid use, and improves quality of life. 1

Understanding Suboxone and Its Role in OUD Treatment

Suboxone contains buprenorphine, a partial opioid agonist that:

• Reduces illicit opioid use by approximately 80% in patients who remain in treatment 2
• Ameliorates the cycle of intense euphoria and withdrawal associated with opioid use 3
• Has safety advantages over full mu agonists because respiratory depression tends to plateau as dose increases 3

Buprenorphine is combined with naloxone in Suboxone to deter misuse, as naloxone precipitates withdrawal if injected.

Treatment Initiation Protocol

Patient Selection

• Patients with moderate to severe opioid use disorder
• Patients must be in mild to moderate withdrawal before starting (to avoid precipitated withdrawal)

Initial Dosing

1. Begin Suboxone when objective signs of moderate opioid withdrawal appear:

   • For short-acting opioids: Not less than 4 hours after last use
   • For long-acting opioids: Not less than 24 hours after last use 1

2. First-day dosing:

   • Start with 4-8mg sublingually
   • May titrate up to total first-day dose of 16mg 1
   • Monitor for signs of precipitated withdrawal

Maintenance Phase

• Typical maintenance dose: 16-24mg daily 1
• Regular monitoring with:
  • Urine drug testing
  • Prescription monitoring program checks
  • Assessment of treatment response and side effects 1

Comprehensive Treatment Approach

Suboxone should be provided as part of a comprehensive treatment plan that includes:

1. Psychosocial Support:

   • Individual drug counseling
   • Cognitive behavioral therapy
   • Mindfulness stress reduction
   • Pain education (for patients with comorbid pain) 3

2. Regular Monitoring:

   • Urine toxicology screening
   • Assessment for continued use of illicit substances
   • Evaluation of medication adherence

3. Management of Comorbidities:

   • Mental health screening and treatment
   • Assessment for other substance use disorders 1

Special Considerations

Pregnancy

• Use buprenorphine alone (without naloxone) in pregnant women
• Coordinate care with obstetric providers 1

Perioperative Pain Management

• Maintain buprenorphine therapy perioperatively (discontinuation increases relapse risk)
• Use adjunct analgesics (NSAIDs, acetaminophen, etc.)
• Add full mu-opioid agonists for breakthrough pain if needed 1

Benzodiazepine Use

• Combination with benzodiazepines increases overdose risk nearly four-fold
• Prescribe naloxone and educate patients and families on its use
• Enhanced monitoring is necessary 1
• Benzodiazepine withdrawal can be more dangerous than opioid withdrawal and requires careful management 1

Hepatic Impairment

• Patients with hepatic impairment may require dose adjustments
• Monitor liver function periodically 1

Duration of Treatment

• Discontinuation of pharmacotherapy significantly increases the risk of relapse
• Patients should be encouraged to continue treatment indefinitely 2
• The goal is durability of recovery over time, rather than rapid dose reduction 3

Potential Adverse Effects

Common side effects include:

• Headache (8-9%)
• Constipation (8-9%)
• Nausea (8-9%)
• Injection-site reactions (with injectable formulations) 4

More serious risks include:

• Respiratory depression (though less than with full opioid agonists)
• Potential for addiction, abuse, and misuse 5
• Serotonin syndrome when combined with serotonergic drugs 5

Important Drug Interactions

• Benzodiazepines and other CNS depressants: Increased risk of respiratory depression, hypotension, and death 5
• CYP3A4 inhibitors (e.g., erythromycin, ketoconazole): May increase buprenorphine levels 5
• CYP3A4 inducers (e.g., rifampin, carbamazepine): May decrease buprenorphine levels 5
• Serotonergic drugs: Risk of serotonin syndrome 5
• MAOIs: Not recommended within 14 days of stopping MAOI treatment 5

Emerging Treatment Options

Newer formulations of buprenorphine may improve adherence and reduce diversion risk:

• Monthly injectable extended-release buprenorphine (BUP-XR) has shown efficacy in clinical trials 4
• Single high-dose buprenorphine protocols are being studied for managing withdrawal 6

By implementing evidence-based treatment with Suboxone and providing comprehensive care, healthcare providers can significantly improve outcomes for patients with opioid use disorder.
