Abstract

Background: Topiramate (TPM) has the potential to become one of the most prominent treatment options for alcohol use disorder (AUD). We investigated the efficacy of TPM for AUD treatment, considering new randomized controlled trials carried out since the publication of four prior investigations. Methods: We searched six major databases, comparing TPM to placebo for AUD treatment. We performed a Bayesian meta-analysis. We conducted a meta-regression, analyzing the effect of age, TPM dosage, duration of treatment, gender, and attrition rate on the outcomes measured. The protocol is registered with PROSPERO: CRD42021286266. Results: TPM reduced heavy drinking days ( d = 0.401, Bayes factor (BF) = 23.088) and weeks ( d = 0.461, BF = 3.784), lowered alcohol craving ( d = 0.477, BF = 107.749), prolonged abstinence throughout the duration of trials ( d = 0.505, BF = 54.998), and decreased the amount of gamma-glutamyl transferase in the blood ( d = 0.345, BF = 39.048). The analysis pointed out that TPM could reduce anxiety ( d = 0.517, BF = 5.993). TPM’s efficacy in relieving alcohol withdrawal, minimizing relapse, and decreasing depressive symptoms was inconclusive. There was evidence of a meta-regression effect of attrition rate on heavy drinking days and craving and length of treatment on abstinence. Conclusion: TPM has the potential to become a key pharmacological agent in the treatment of AUD.

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.
