Aim Impulsivity has been identified as a key relapse risk factor in patients with alcohol use disorder (AUD); however, the inherent characteristics of this relationship have been largely understudied. The heterogeneity of AUD and variation in impulsivity constructs require careful consideration to inform future work examining the relationship. This study sought to review empirical findings examining facets of impulsivity and AUD relapse. Methods A systematic search strategy was employed to capture studies on impulsivity measures related to AUD relapse. Impulsivity measures were qualitatively organized in terms of ‘trait impulsivity’—typically measured by self-report questionnaires—and ‘behavioural impulsivity’, i.e. ‘motor impulsivity’, ‘impulsive choice’ and ‘reflection impulsivity, assessed with cognitive–behavioural tasks. Results Seventeen peer-reviewed papers were identified. Relapse outcomes varied substantially in relation to impulsivity measures. Twelve papers included aspects of ‘trait impulsivity’, and nine studies included ‘behavioural impulsivity’ measures, from which five studies dealt with the ‘impulsive choice’ subcategory. The Barratt Impulsivity Scale was the self-report questionnaire that was most frequently used. Conclusions All three included facets of impulsivity (‘trait-, motor- and impulsive choice impulsivity’) were associated with AUD relapse, but none seemed to be superior to another. This study confirmed that research on the relation between impulsivity and AUD relapse is relatively scarce. Future research and treatment options are proposed.

Oral naltrexone, an opioid antagonist, reduces relapse and heavy drinking in alcohol-dependent patients. However, oral delivery is associated with poor compliance and adverse events. To enhance treatment outcome and reduce side effects, injectable extended-release naltrexone formulations have been developed. Currently, there are no studies available directly comparing oral and injectable formulations of naltrexone in alcohol-dependent patients. This paper reviews the efficacy and adverse events of oral versus injectable extended-release naltrexone. Therefore, data were extracted from two recently published reviews about oral naltrexone in the treatment of alcohol dependence. Pooled outcomes were compared with reported outcomes of recent studies on injectable extended-release naltrexone. Injectable naltrexone seems to be effective in the management of alcohol dependence. Although inconclusive, the available results indicate that the expected advantages of injectable naltrexone over oral naltrexone still have to be proven. Randomized studies with direct comparisons of oral and injectable naltrexone are urgently needed.
