Abstract

AIMS: Two previous randomized trials found an effect for bupropion in reducing methamphetamine use in the subgroup with lower frequency of methamphetamine use at baseline. This study aimed to replicate these results by comparing bupropion versus placebo in methamphetamine-dependent participants with less than daily methamphetamine use at baseline. METHODS: Methamphetamine-dependent volunteers reporting methamphetamine use on ≤29 of past 30 days were randomized to bupropion 150 mg twice daily (n = 41) or placebo (n = 43) and out-patient counseling for 12 weeks. The primary outcome was the proportion achieving end-of-treatment (EOT) methamphetamine abstinence (weeks 11 and 12) for bupropion versus placebo. A post-hoc analysis compared EOT abstinence by medication adherence assessed via plasma bupropion/hydroxybupropion level. RESULTS: There was no significant difference in EOT abstinence between bupropion (29%, 12 of 41) and placebo (14%, six of 43; P = 0.087). Among participants receiving bupropion, EOT abstinence was significantly higher in participants assessed as medication adherent by plasma bupropion/hydroxybupropion levels (54%, seven of 13) compared to non-adherent participants (18%, five of 28; P = 0.018). Medication adherence by plasma levels was low (32%). CONCLUSIONS: Bupropion may be efficacious for reducing methamphetamine in people with less than daily baseline methamphetamine use, but the evidence remains inconclusive.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Various pharmacologic and psychosocial therapies for MUD/PMU have been explored in the literature.

    “Although various pharmacologic (e.g., bupropion [22, 23], mirtazapine [24, 25], varenicline [26]) and psychosocial (e.g., cognitive behavioural therapy [27], contingency management [28, 29], Matrix model [30]) therapies for MUD/PMU have been explored in the literature, the best approach to treatment remains unclear.”
  • Among studies reporting race (n = 34), the majority of patients were Caucasian in all but four studies.

    “Among studies reporting race (n = 34), the majority of patients were Caucasian in all but four studies [23, 69, 73, 102].”

    From Psychosocial and pharmacologic interventions for problematic methamphetamine use: Findings from a scoping review of the literature (2023) · cites this paper as [23]

    The Results section (Sample Characteristics; page unavailable) says participant demographics are shown in Table 1, but the passages available from our copy do not give the racial breakdown. Searches for Caucasian, White, race, and ethnicity did not establish whether this trial was one of the four exceptions. This single trial also cannot establish the citing paper’s count across 34 studies. (LLM, conf=0.72)

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.
