BACKGROUND AND OBJECTIVES: Exposure-based interventions (EBIs) are the first-line treatment for anxiety disorders and posttraumatic stress disorder. Although common, the association between EBIs and benzodiazepines is controversial. Therefore, we systematically reviewed the literature to evaluate if benzodiazepines could undermine the efficacy of EBIs in treating these disorders.
METHODS: We conducted a systematic review aiming for randomized clinical trials (RCTs) in ISI Web of Science, Scopus, PubMed/MEDLINE, and PsycINFO databases. We scrutinized the reference list of selected papers and other systematic reviews. Finally, we evaluated the methodological quality and the scientific evidence of the studies.
RESULTS: We screened 1,529 studies and included 12 RCTs in this review (all showing some concerns or high risk of bias). Benzodiazepines did not impact the efficacy of EBIs in nine studies at posttreatment, improved efficacy in two, and reduced it in one. In the follow-up, benzodiazepines (after its discontinuation) did not impact the efficacy in six studies and reduced it in five. The scientific level of evidence achieved was B for both phases.
CONCLUSIONS: Until now there is no definitive evidence that benzodiazepines could hinder the EBIs' efficacy for treating posttraumatic stress disorder and anxiety disorders.
