Introduction: Alcohol use disorder (AUD) is prevalent and recognized as a chronic, relapsing disorder. Even though effective treatment options are available, AUD is strongly undertreated. As adjuvant treatment strategies accompanying psychosocial treatments, pharmacological strategies can increase the efficacy of AUD treatment options.
Areas covered: After giving a brief update of epidemiology, neurobiology and treatment rationales for AUD, the review outlines pharmacological interventions against the background of current evidence. These include approved substances like naltrexone, nalmefene, acamprosate and disulfiram, second line medications like topiramate, baclofen and varenicline and novel approaches like hallucinogens. The review refers to the primary database on pharmacotherapies for AUD and to findings from pairwise and network meta-analyses. It illustrates effects of pharmacotherapies for AUD on different outcomes and assesses risks and benefits of treatment strategies. Search has been conducted in PubMed using the substance name or related categories (such as anti-craving or relapse prevention) as key words.
Expert opinion: Improved understanding of AUDs neurocircuitry expands the range of available pharmacotherapeutic strategies for supporting abstinence and drinking reduction. Pharmacotherapies for AUD can be improved by understanding differences in treatment response. Matching different treatment approaches to individual needs can challenge the view of alcohol dependence as a lifelong disorder.
