Abstract

Aims: Although debates over the efficacy of oral naltrexone and acamprosate in treating alcohol use disorders tend to focus on their global efficacy relative to placebo or their efficacy relative to each other, the underlying reality may be more nuanced. This meta‐analysis examined when naltrexone and acamprosate are most helpful by testing: (i) the relative efficacy of each medication given its presumed mechanism of action (reducing heavy drinking versus fostering abstinence) and (ii) whether different ways of implementing each medication (required abstinence before treatment, detoxification before treatment, goal of treatment, length of treatment, dosage) moderate its effects. Methods: A systematic literature search identified 64 randomized, placebo‐controlled, E nglish‐language clinical trials completed between 1970 and 2009 focused on acamprosate or naltrexone. Results: Acamprosate had a significantly larger effect size than naltrexone on the maintenance of abstinence, and naltrexone had a larger effect size than acamprosate on the reduction of heavy drinking and craving. For naltrexone, requiring abstinence before the trial was associated with larger effect sizes for abstinence maintenance and reduced heavy drinking compared with placebo. For acamprosate, detoxification before medication administration was associated with better abstinence outcomes compared with placebo. Conclusions: In treatment for alcohol use disorders, acamprosate has been found to be slightly more efficacious in promoting abstinence and naltrexone slightly more efficacious in reducing heavy drinking and craving. Detoxification before treatment or a longer period of required abstinence before treatment is associated with larger medication effects for acamprosate and naltrexone respectively.

  • Acamprosate is one of three FDA-approved medications for AUD and has an effect size similar to SSRIs for depression.

    “With regard to non-alcohol-like drugs, acamprosate is one of three Food and Drug Administration-approved medications for the treatment of AUD that is widely prescribed worldwide, and it has an effect size (Mason, 2003;Maisel et al., 2013;Jonas et al., 2014) that is similar to selective serotonin reuptake inhibitors for depression (Schalkwijk et al., 2014).”

    From Drug Addiction: Hyperkatifeia/Negative Reinforcement as a Framework for Medications Development (2021) · cites this paper as Maisel et al., 2013

    The Results (End-of-Treatment Outcomes; page unavailable) report effect sizes for acamprosate in treating alcohol use disorders, supporting the part of the sentence for which Maisel et al. is cited. The copy does not establish that acamprosate is one of three FDA-approved medications; the Discussion (Concluding Comments; page unavailable) says its effects are somewhat smaller than those of medications for depression, rather than establishing similarity to SSRIs. The SSRI comparison is separately cited to Schalkwijk et al. (LLM, conf=0.87)

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.
