Resumo
Objetivo: Essa revisão tem como objetivo mostrar os estudos relacionados com a molécula de acetilcisteína na doença de Alzheimer, a hipótese glutamatérgica, e a mostrar diferença deste fármaco no uso de medicamentos e suplementos alimentares. Métodos: A revisão integrativa foi realizada em 6 etapas detalhados, os artigos para construção da pesquisa foram obtidos a partir das bases de dados Scopus; Scielo; MEDLINE, disponível na Universidade Federal de Paraná-UFPR, através do acesso CAFe. Pelos operadores booleanos "AND" e "OR", os termos definidos para a recolha de dados foram obtidos através dos Descritores em Ciências da Saúde (DeCS/MeSH). Resultados: Foi encontrado um total de 68 estudos, divididos entre os autores; e utilizando os critérios de inclusão e exclusão, restaram apenas 7 estudos, no qual foram adicionados à pesquisa após terem sido lidos por completo; os estudos que demonstraram melhor afinidade no uso da molécula acetilcisteina associada com Alzheimer em teste in vivo ou in vitro foram narrados na integra. Considerações finais: Na pesquisa foi possível verificar que a utilização de N-acetilcisteína off label pode ser uma molécula alvo para a doença de Alzheimer, mas para provar está ação recomenda-se a realização de mais estudos para garantir a sua eficácia.
