Objective: To review the literature evaluating gabapentin for alcohol withdrawal and dependence. Data Sources: A literature search of MEDLINE (1966 to end of March 2015) and PubMed was performed using the terms alcohol, gabapentin, withdrawal, and dependence. Additional references were identified from a review of literature citations. Study Selection and Data Extraction: English-language prospective studies evaluating gabapentin for alcohol withdrawal and dependence were evaluated. Data Synthesis: A total of 10 publications utilizing gabapentin in alcohol withdrawal (n = 5) and alcohol dependence (n = 5) were included in this review. Limited data suggest that gabapentin can provide benefit in managing mild alcohol withdrawal syndrome. There were 5 reported or suspected seizures in the withdrawal studies, suggesting that additional safety data are necessary before gabapentin monotherapy can be routinely considered. Sleep and mood/anxiety-related outcomes were positively influenced by gabapentin, which may result in long-term benefits if continued beyond the withdrawal period for the treatment of alcohol dependence. Studies evaluating gabapentin for alcohol dependence demonstrated dose-dependent benefits for complete abstinence, rates of no heavy drinking, and cravings. Gabapentin used to treat alcohol dependence was well tolerated with no severe adverse reactions reported in the extant literature. Conclusion: Gabapentin may have a role in the treatment of mild alcohol withdrawal, but future studies should focus on adequate dosing strategies. Gabapentin should be considered for the treatment of alcohol dependence when barriers prevent the use of traditional agents. Additional studies should be conducted to further validate findings from the research conducted to date, but the current literature is promising for gabapentin in the treatment of alcohol dependence.

BackgroundAlcohol withdrawal accounts for a significant amount of hospital admissions and can quickly progress to the development of delirium tremens (DTs), seizures, and death. Rapid identification and management of alcohol withdrawal syndrome (AWS) is vital and can be managed with a number of different treatment strategies. Diazepam loading is a treatment strategy that utilizes the pharmacokinetics of this agent to achieve a rapid reduction in symptoms followed by sustained benefit over a period of days.ObjectiveThe purpose of this review is to evaluate the role of diazepam loading for AWS.MethodsA literature search of four databases—Pubmed, PsychInfo, Biosis, and Embase—was conducted to identify publications between 1960 and August 2011 that described the use of diazepam loading for the treatment of AWS. Eight trials, both open‐label and controlled trials were identified. Only four randomized controlled‐trials (RCTs) have been published and they are reviewed in this paper.ResultsIncluded trials of hospitalized inpatients found that diazepam loading provided rapid symptom relief as well as reduced the incidence of seizures and duration of DTs. In patients diagnosed with severe DTs, rapidly administered doses of diazepam produced a quick calming effect. While no adverse events resulting from diazepam loading were noted, no formal assessment tool was used to evaluate its safety. Larger randomized controlled‐trials are needed to better evaluate safety outcomes.ConclusionsDiazepam loading is an effective treatment option for hospitalized patients experiencing AWS. Diazepam loading uses the concept of symptom‐triggered therapy, a mainstay of current AWS treatment, while exploiting its prolonged elimination half‐life and eliminating the need for additional pharmacologic therapy. Studies reviewed found diazepam loading significantly improved a number of important outcomes in AWS, including time in DTs, compared to traditional treatment strategies. (Am J Addict 2013;22:113‐118)
