Buprenorphine: a new maintenance opiate?

S S Seow, A J Quigley, K F Ilett

    The Medical Journal of Australia
    |April 14, 1986
    PubMed
    Summary

    Sublingual buprenorphine is an acceptable maintenance treatment for heroin dependence. Higher doses (4 mg) reduced withdrawal symptoms and drug abuse, but gradual detoxification is needed.

    Area of Science:

    • Addiction Medicine
    • Pharmacology
    • Clinical Psychology

    Background:

    • Opioid dependence is a significant public health issue.
    • Buprenorphine is an effective medication for opioid maintenance therapy.
    • Understanding optimal dosing and withdrawal protocols is crucial.

    Purpose of the Study:

    • To assess the acceptability of sublingual buprenorphine for opioid maintenance.
    • To determine the effects of abrupt buprenorphine withdrawal and reintroduction.
    • To evaluate dose-dependent effects on intoxication, withdrawal, and drug abuse.

    Main Methods:

    • A controlled study involving heroin-dependent outpatients.
    • Administration of 2 mg or 4 mg of sublingual buprenorphine.
    • Assessment of withdrawal symptoms, intoxication, and drug abuse via self-report and urine assays.

    Main Results:

    • The 4 mg buprenorphine dose led to greater reported intoxication and fewer withdrawal symptoms compared to 2 mg.
    • Higher buprenorphine doses were associated with reduced abuse of opioids and benzodiazepines.
    • Abrupt withdrawal caused mild discomfort, while reintroduction stabilized patients.
    • Opiate drug use, confirmed by urine assays, increased from 15% to 50% over the study period.

    Conclusions:

    • Sublingual buprenorphine is a viable maintenance treatment option for opioid-addicted outpatients.
    • Doses exceeding 4 mg daily may be necessary to effectively curb concurrent opiate abuse.
    • Gradual tapering is recommended for buprenorphine detoxification to manage withdrawal symptoms.
