Resumen
Objetivo: Esta revisión tiene como objetivo mostrar los estudios relacionados con la molécula de acetilcisteína en la enfermedad de Alzheimer, la hipótesis glutamatérgica, y para mostrar la diferencia de este fármaco en el uso de medicamentos y suplementos alimentícios. Métodos: La revisión integradora se realizó en 6 pasos detallados, los artículos para la construcción de la investigación se obtuvieron de las bases de datos Scopus; Scielo; MEDLINE, disponible en la Universidad Federal de Paraná-UFPR, a través del acceso CAFe. Mediante los operadores booleanos "AND" y "OR", los términos definidos para la recogida de datos se obtuvieron a través de los Descriptores en Ciencias de la Salud (DeCS/MeSH). Resultados: Se encontró un total de 68 estudios, divididos entre los autores; y utilizando los criterios de inclusión y exclusión, sólo quedaron 7 estudios, en los cuales fueron añadidos a la búsqueda después de ser leídos en su totalidad; los estudios que mostraron mejor afinidad en el uso de la molécula de acetilcisteína asociada a la prueba de Alzheimer in vivo o in vitro fueron narrados en su totalidad. Consideraciones finales: En la investigación fue posible verificar que el uso de N-acetilcisteína fuera de etiqueta puede ser una molécula de ayuda para la enfermedad de Alzheimer, pero para probar esta afirmación se recomienda la realización de más estudios para garantizar su eficacia.
