Abstract

BACKGROUND: Office-based treatment of opiate addiction with a sublingual-tablet formulation of buprenorphine and naloxone has been proposed, but its efficacy and safety have not been well studied. METHODS: We conducted a multicenter, randomized, placebo-controlled trial involving 326 opiate-addicted persons who were assigned to office-based treatment with sublingual tablets consisting of buprenorphine (16 mg) in combination with naloxone (4 mg), buprenorphine alone (16 mg), or placebo given daily for four weeks. The primary outcome measures were the percentage of urine samples negative for opiates and the subjects' self-reported craving for opiates. Safety data were obtained on 461 opiate-addicted persons who participated in an open-label study of buprenorphine and naloxone (at daily doses of up to 24 mg and 6 mg, respectively) and another 11 persons who received this combination only during the trial. RESULTS: The double-blind trial was terminated early because buprenorphine and naloxone in combination and buprenorphine alone were found to have greater efficacy than placebo. The proportion of urine samples that were negative for opiates was greater in the combined-treatment and buprenorphine groups (17.8 percent and 20.7 percent, respectively) than in the placebo group (5.8 percent, P<0.001 for both comparisons); the active-treatment groups also reported less opiate craving (P<0.001 for both comparisons with placebo). Rates of adverse events were similar in the active-treatment and placebo groups. During the open-label phase, the percentage of urine samples negative for opiates ranged from 35.2 percent to 67.4 percent. Results from the open-label follow-up study indicated that the combined treatment was safe and well tolerated. CONCLUSIONS: Buprenorphine and naloxone in combination and buprenorphine alone are safe and reduce the use of opiates and the craving for opiates among opiate-addicted persons who receive these medications in an office-based setting.

  • Buprenorphine-naloxone treatment for opioid use disorder is medically effective, improving treatment retention and reducing illicit opioid use.

    “Treatment of OUD with B/N has been shown to be medically effective (increasing retention in treatment and decreasing use of illicit opioids) and cost-effective.3–8”
  • Participants' demographic characteristics were similar to those reported in other U.S. and international studies of office-based buprenorphine/naloxone maintenance.

    “While participants’ demographic characteristics were similar to those reported in other U.S. and international studies of office-based buprenorphine/naloxone maintenance, our study sample is not necessarily representative of all opioid-dependent patients.13–15”
  • In a randomized controlled trial comparing buprenorphine/naloxone formulation with placebo over 4 weeks in patients with opiate dependence, mean craving more than halved, with a baseline score of 62.4 reducing to 29.8 after 4 weeks of treatment with a sublingual tablet formulation of 16 mg buprenorphine/4 mg naloxone (p < 0.0001).

    “In this study, where craving was measured on a 0–100 mm VAS, mean craving more than halved, with a baseline score of 62.4 reducing to 29.8 after 4 weeks of treatment with a sublingual tablet formulation of 16 mg buprenorphine/4 mg naloxone (p < 0.0001, Figure 4 ) [(111) and unpublished data].”
  • Buprenorphine maintenance is quite safe, with adverse events equivalent to methadone and placebo in phase III research.

    “phase III research reports indicate that buprenorphine maintenance is quite safe with equivalent adverse events to methadone and placebo”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
