Uso abusivo de benzodiazepínicos em idosos: revisão bibliográfica

Abstract

Objectives: To identify the consequences of abuse of benzodiazepines among elderly people, as well as to determine the benzodiazepines most consumed in Brazil. Methodology: A narrative literature review was carried out using Google Scholar, through the keywords benzodiazepines, abuse and elderly (in Portuguese), as well as their combinations. Conclusion: Among the most frequently used benzodiazepines, one may find diazepam, bromazepam, alprazolam, lorazepam, clonazepam and midazolam. The main side effects of these drugs among the elderly are sedation, psychomotor retardation, cognitive impairment (reduced attention span, forgetfulness, mental confusion), dependence and absence syndrome (insomnia, irritability and anxiety). The cerebellar toxicity can generate impaired speaking and coordination and unstable posture, increasing the risk of falls and fractures.
