    High doses of methadone initially reduce illicit drug use in treatment programs. However, lower doses become more effective as treatment duration increases, with stricter client selection improving outcomes.

    Area of Science:

    • Addiction Medicine
    • Pharmacology
    • Public Health

    Background:

    • Methadone maintenance therapy is a cornerstone for opioid use disorder treatment.
    • Understanding dose-response relationships and programmatic impacts is crucial for optimizing treatment efficacy.
    • Client adherence and illicit substance use are key indicators of treatment success.

    Purpose of the Study:

    • To analyze the relationship between methadone dosage, treatment duration, and illicit drug use in a diverse client population.
    • To evaluate the impact of programmatic changes, including client selection, on treatment outcomes.
    • To identify optimal methadone dosing strategies for reducing illicit drug use over time.

    Main Methods:

    • Analysis of data from 155 clients in a methadone treatment program.

  • Assessment of methadone administration adherence (spottiness) and urine drug screen results.
  • Evaluation of data across three distinct time periods reflecting programmatic changes.
  • Main Results:

    • High initial methadone doses effectively reduced illicit drug use.
    • Efficacy of lower methadone doses in reducing illicit drug use increased with longer treatment duration.
    • A more stringent client selection procedure significantly reduced illicit drug use.

    Conclusions:

    • Methadone dosage adjustments based on treatment duration may enhance efficacy.
    • Programmatic interventions, such as improved client selection, can positively impact treatment outcomes.
    • Optimizing methadone treatment requires consideration of both pharmacological and operational factors.
