RESUMOA polifarmácia é um fator que tem grande impacto na segurança do paciente idoso, tendo em vista que é a grande responsável pelas interações medicamentosas. Os objetivos da presente pesquisa são identificar a prevalência e os fatores associados à polifarmácia. A metodologia utilizada foi estudo quantitativo descritivo prospectivo, baseado em análise documental por meio de um instrumento semiestruturado, analisando-se os dados no programa estatístico SPSS 20.0. Os resultados demonstraram que a média de idade foi de 71,9 anos, e 52,7% mulheres. O tempo de internação obteve uma média de 21,7 dias, a média de diagnósticos por paciente foi de 2,6. O principal diagnóstico de internação hospitalar foi doenças do aparelho circulatório (20,3%). A média de medicamentos prescritos por paciente foi de 6,8. Os medicamentos mais utilizados faziam parte do sistema digestório e metabólico (32,4%), a prevalência de prescrição de medicamentos potencialmente inadequados durante as internações avaliadas foi de 11,2%. Em relação às potenciais interações medicamentosas, foram identificadas em 65,5% das prescrições e os medicamentos mais envolvidos nas interações fazem parte do sistema cardiovascular (38,6%). Diante de tais resultados, verifica-se a necessidade de adotar estratégias para a otimização da farmacoterapia prestada ao paciente idoso.Palavras-chave: Medicamento. Prescrição. Polifarmácia.

PREVALENCE AND FACTORS ASSOCIATED WITH POLYPHARMACY AMONG THE ELDERLY A PUBLIC HOSPITAL ABSTRACTPolypharmacy is a factor that has great impact on the security of the elderly patient, considering that is largely responsible for drug interactions. The objectives of this research were to identify the prevalence and factors associated with polypharmacy. The methodology used was a prospective descriptive quantitative study based on document analysis through a semi-structured instrument, analyzing the data in SPSS 20.0. The results demonstrated that the mean age was 71.9 years, 52.7% female. The length of stay scores a 21.7 days, the average number of diagnoses per patient was 2.6. The main hospital was diagnosed with diseases of the circulatory system (20.3%). The average number of drugs prescribed per patient was 6.8. The most used drugs were part of the digestive and metabolic system (32.4%), the prevalence of potentially inappropriate prescription drugs evaluated during hospitalization was 11.2%. With regard to potential drug interactions, were identified in 65.5% of prescriptions drugs most involved in the interactions are part of the cardiovascular system (38.6%). Given these results, there is the need to adopt strategies for the optimization of pharmacotherapy given to the elderly.
espécie existe principalmente nos Estados do Acre, Amazonas, Amapá, Roraima e Pará. Na medicina popular, Stryphnodendron adstringens (Mart.) é uma planta utilizada no tratamento de algumas patologias como: gonorreia, leucorreia, diarreia, úlceras, hemorragias vaginais, impinges, assim como, pode ser usada como agente anti-inflamatório, cicatrizante, adstringente, hemostático, antisséptico e anti-hipertensivo. O barbatimão possui vários compostos produzidos pelo seu metabolismo secundário, como: os alcaloides, terpenos, flavonoides, esteroides e taninos. A atividade farmacológica dessa planta é devido principalmente ao teor de taninos presentes na espécie. Dessa forma, esta revisão aborda uma breve descrição botânica, taxonomia e distribuição geográfica, assim como os aspectos etnobotânicos, fitoquímicos e farmacológicos da espécie. AbstractStryphnodendron adstringens (Mart.) is widely distributed in five Brazilian regions, popularly known as
Total levels of caffeoylquinic, p-coumaric, and benzoic acid derivatives, flavonols, and dihydroflavonols were investigated in 44 brown propolis samples from the state of Paraná(Brazil) together with their cytotoxicity and antibacterial activities. The aim was to discover chemical and biological activity-based patterns. Great quantitative variation was found within individual samples; however, a typical extract might contain 11.14−21.45 mg of caffeoylquinic acid derivatives/g, 6.27−12.17 mg of p-coumaric acid derivatives/g, 3.18−7.45 mg of benzoic acid derivatives/g, 9.35−23.55 mg of flavonols/g, and 0.17−4.25 mg of dihydroflavonols/g. MIC values poorly correlated to the levels of p-coumaric acids, flavonols, and dihydroflavonols. Most propolis samples showed medium-to-high cytotoxic activity against at least one tumoral cell. The most susceptible cell was OVCAR-8, followed by SF-295, but no correlation was found between the inhibition of OVCAR-8 and SF-295 and levels of any chemical class investigated. The concentration of bioactive compounds in brown propolis samples together with biological activities distinguished samples produced in northern, southern, eastern, and western Parana, being characteristics associated with the geographical origin, and may help to establish a pattern for the propolis produced in the state of Parana.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
