Methadone Treatment

What is Methadone

Methadone is a long-acting opioid agonist medication used in medication-assisted treatment (MAT) for opioid use disorder. It activates opioid receptors in the brain, reducing cravings and withdrawal symptoms. Methadone is taken orally once daily at opioid treatment programs (OTPs).

  • Mechanism as medication-assisted treatment: Methadone is a full opioid agonist that activates receptors targeted by opioids of misuse. This prevents withdrawal and reduces cravings.
  • OTP principle: Methadone is only provided through certified OTPs with regular urine testing and counseling. Take-home doses are limited until patients demonstrate stability.

Societal Perspectives on Methadone Treatment

Methadone maintenance is controversial, with stigma around substituting one opioid for another. However, research shows MAT with methadone is an evidence-based treatment for opioid addiction. When taken as prescribed, methadone stabilizes patients, allowing them to function normally.

Methadone Distribution

Description of monitoring and regulations:

  • Urine testing: Methadone maintenance patients must undergo at least eight randomized tests in the first year of treatment to detect any unsanctioned drug use.
  • Take-home requirements: During the first 14 days of treatment, the take-home supply of methadone is limited to a 24-hour dose. After demonstrating progress, take-home doses can gradually increase up to 30 days maximum.
  • Monitoring: Methadone treatment programs should have an interprofessional team including physicians, nurses, and counselors to monitor patient progress.
  • Prescription drug monitoring: Clinicians should review PDMP data to carefully cross-reference opioid dosage history when starting methadone, as it has a narrow therapeutic window.

Riverside County Drug Classifications

Opioids, stimulants, depressants, hallucinogens, and cannabis are classified under Schedule I-V drug categories in California.

Methadone Treatment Effectiveness Research

Methadone is an effective medication for treating opioid use disorder used since 1947.

Evidence for Effectiveness

Studies show methadone reduces opioid use, disease transmission, and crime:

  • 33% fewer opioid-positive drug tests for methadone patients
  • Patients on methadone maintenance are 4.44 times more likely to stay in treatment
  • Retention in methadone treatment reduces overdose risk, HIV transmission, and increases employment

Major Drawbacks

  • Potential for misuse/diversion if not taken as prescribed
  • Severe withdrawal symptoms if methadone is stopped suddenly
  • Possible QTc prolongation/cardiac issues in some patients
  • Respiratory depression/overdose risk when combined with other CNS depressants

Comparison to Other Medications

Methadone and buprenorphine are equally effective in reducing illicit opioid use.

Methadone has demonstrated benefits but also risks requiring careful management.
