Pharmacotherapeutic options for co-morbid depression and alcohol dependence.

INTRODUCTION: Depression and alcohol dependence are frequently co-morbid and among the most prevalent mental disorders. They are a serious global health problem with social, interpersonal, and legal interpolations. Among pharmacological alternatives, anti-craving compounds as well as antidepressants, antipsychotics, anticonvulsants, benzodiazepines, and beta-blockers have shown efficacy for depression as well as alcohol consumption. The pharmacological treatment of both complex interwoven mental diseases is still challenging given the inconsistent results of open and double-blind randomized placebo-controlled studies with approved and open label medications. AREAS COVERED: The authors provide a systematic review of the literature with PubMed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to obtain an overview of the pharmacotherapeutic options for co-morbid depression and alcohol dependence. EXPERT OPINION: The effect of treating only depressive or alcohol-related symptoms appears limited. Therapies directly targeting the addiction are warranted among such dually diagnosed patients. Despite limited data, the reviewed pharmacotherapeutic treatments demonstrated efficacy in most but not in all relevant parameters of alcohol dependence and depression.
