          Abstract

          Este estudo objetiva realizar levantamento bibliográfico para verificar a possível influência da Levodopa sobre a fase oral da deglutição de indivíduos com Doença de Parkinson. Foi realizado levantamento bibliográfico em periódicos indexados no Science Direct, periódicos Capes, LILACS, SciELO, MedLine e Scopus e livros. Para busca foram utilizados os termos disfagia, medicamentos, levodopa, Parkinson, dysphagia, drugs, swallowing disorders, Parkinson's disease, disfagia, las drogas e enfermedad de parkinson. Foram identificados 16 artigos internacionais e 25 nacionais, após a leitura de todos os artigos identificados foram selecionados 32, utilizaram-se ainda quatro livros e um resumo de anais de congresso. Para tal seleção utilizou-se como critério de inclusão aqueles artigos que considerassem o comprometimento causado pela Doença de Parkinson, especialmente na fase oral da deglutição, bem como os efeitos da levodopa sobre a mesma, e como critério de exclusão a influência do fármaco na fase faríngea, pois geralmente ele parece ter maior efeito na fase oral. Existe discordância na literatura quanto aos possíveis efeitos da Levodopa na deglutição. Quando estes ocorrem, geralmente afetam a fase oral desta função, uma vez que as dificuldades que o portador da Doença de Parkinson já apresenta são maximizadas pela xerostomia decorrente da administração deste fármaco. Em virtude da grande diversidade dos resultados dos estudos encontrados, faz-se necessária a realização de estudos controlados para uma elucidação mais detalhada dos efeitos da Levodopa na deglutição.

          Translated abstract

          The purpose of this study is to conduct a literature review in order to verify the possible influence of Levodopa on the oral phase of deglutition in individuals with Parkinson disease. The survey was conducted in journals indexed in Science Direct, Capes periodicals, LILACS, SciELO, MedLine and Scopus, as well as in books. For this survey, the terms disfagia/dysphagia/disfagia, medicamentos/drugs/las drogas, levodopa, Parkinson/Parkinson disease/ enfermedad de Parkinson and swallowing disorders were used. It was possible to identify 16 international and 25 national scientific articles. After reading every identified papers, 32 were selected in addiction to four books and one abstract published in scientific conference proceedings were used. For such selection, the inclusion criteria were the papers which considered the impairments caused by Parkinson´s disease, especially during the oral phase of swallowing, as well as the effects of levodopa about it. As exclusion criteria, the drug influence during pharyngeal phase was considered, because it usually seems to have higher effect during oral phase. There is disagreement in the literature surveyed considering Levodopa possible effects in deglutition. When these effects occur, they generally affect the oral phase of this function, since difficulties already present in Parkinson Disease carriers are maximized by the xerostomia due to the administration of this drug. Considering the vast range of results found in the studies surveyed, developing controlled studies for a detailed elucidation of Levodopa effects in deglutition becomes necessary.

            Prescription drugs and their effects on swallowing.

            The impact of medications on the physiology of swallowing has received much attention in dysphagia literature. This article reviews the potential effects of medications commonly prescribed in an adult continuing care and rehabilitation facility on swallowing. An audit of medications prescribed to 153 adults accessing age-related respiratory, neurology, and learning disability services was performed. This was followed by an investigation of relevant sources to identify the potential side effects of these medications. One side effect, namely, xerostomia, which our investigations revealed could be a side effect of 24.8% of the medications used at our institution, was further investigated. The prevalence of xerostomia was then investigated in a randomly selected sample of ten subjects whose dysphagia had been confirmed by videofluoroscopy. It was found that six of the ten dysphagic clients displayed xerostomia. Review of the medications of these ten subjects indicated that all were using from three to nine drugs that could cause xerostomia. This article highlights the need for health-care professionals to consider the potential effects of these medications on swallowing and, indeed, the general presentation of clients.
