ABSTRACT

AIM: To evaluate the potential drug-drug interactions (PDDI) between drugs used by older adults, any associated factors and recommended clinical management. METHODS: A cross-sectional, population-based study was carried out through a home survey of 934 older adults (from December 2009 to April 2010). A questionnaire was applied, and the participants were asked to show all the drugs used and their respective prescriptions, thus providing data to identify polypharmacy, self-medication and PDDI. PDDI, their consequences, severity and clinical management were identified using Micromedex. RESULTS: Overall, 2846 drugs and 665 PDDI were identified, 71.0% of which were moderate and 22.4% serious. The prevalence of PDDI was 36.9%. Drugs with a narrow therapeutic index were involved in 17.0% of the PDDI. The variables female sex (PR = 1.11, 95% CI 1.02-1.20), age ≥80 years (PR = 1.15, 95% CI 1.03-1.28), no polypharmacy (PR = 0.72, 95% CI 0.67-0.78) and no hospitalization in the past year (PR = 0.90, 95% CI 0.82-0.97) remained associated with the presence of three or more PDDI in the final multivariate analysis model. CONCLUSIONS: Most PDDI were related to routinely used drugs (enalapril, hydrochlorothiazide, calcium, captopril, levothyroxine and simvastatin), and more than one-third of the older adults were exposed to PDDI with the possible risk of serious health consequences. Drugs with a narrow therapeutic index were involved in several PDDI, with increased risk of toxicity. The clinical management procedures most recommended are dose adjustment and dosing changes, control of the drugs' serum levels, and monitoring of the clinical conditions.

ABSTRACT

OBJECTIVE: To analyze the pattern of use of medications use in aged people and associate it with socioeconomic aspects and with the self-rated health. METHODS: A population-based cross-sectional design study with 934 elderly people from Goiania, Midwestern Brazil, between December 2009 and April 2010. Data were collected through a questionnaire. The dependent variable was the number of medications consumed and the independent variables were sex, marital status, education, type of residence, age, income, and self-rated health. Drugs were classified according to the Anatomical Therapeutic Chemical Classification. The inappropriate drugs for the elderly were identified according to the Beers-Fick criteria. The tests used were Chi-square and Fisher's exact test, p was considered significant when < 0.05. RESULTS: The elderly consumed 2,846 medicines (3.63 medications/person). The most commonly consumed were those which act in the cardiovascular system (38.6%). The prevalence of polypharmacy was 26.4% and self-medication was 35.7%. The most used drugs for self-medication were analgesics (30.8%), 24.6% of the elderly consumed drug considered inappropriate. Women, widows, those aged 80 or over and with worse self-rated health were more likely to practiced more polypharmacy. Most self-medication was associated with lower levels of education and worse self-rated health. CONCLUSIONS: The pattern of drug use by the elderly was similar to that found in the elderly in other regions of Brazil. The number of drugs used, the prevalence of self-medication and practice of polypharmacy and inappropriate drug use were within the national average.

ABSTRACT

OBJETIVO: Analisar o padrão de consumo de medicamentos entre idosos e sua associação com aspectos socioeconômicos e autopercepção de saúde. MÉTODOS: Estudo de base populacional e delineamento transversal com 934 idosos de Goiânia, GO, Brasil, entre dezembro de 2009 e abril de 2010. Os dados foram coletados por meio de questionário. As variáveis estudadas foram: número de medicamentos consumidos, sexo, estado civil, escolaridade, tipo de moradia, idade, renda e autopercepção de saúde. Os medicamentos foram classificados segundo o Anatomical Therapeutic and Chemical Classification. Os medicamentos impróprios para idosos foram identificados segundo o Critério de Beers-Fick. Os testes utilizados foram Qui-quadrado (X²) e exato de Fisher e p foi considerado significativo quando < 0,05. RESULTADOS: Os idosos consumiam 2.846 medicamentos (3,63 medicamentos/idoso). Os mais usuais atuavam no aparelho cardiovascular (38,6%). A prevalência de polifarmácia foi de 26,4% e da automedicação de 35,7%. Os medicamentos mais ingeridos por automedicação foram os analgésicos (30,8%); 24,6% dos idosos consumia medicamento considerado impróprio. Mulheres, viúvos, idosos com 80 anos ou mais e com pior autopercepção de saúde praticavam mais a polifarmácia. A maior prática da automedicação esteve associada com menor escolaridade e pior autopercepção de saúde. CONCLUSÕES: O padrão do consumo de medicamentos por idosos foi semelhante ao encontrado em idosos de outras regiões do Brasil. O número de medicamentos usados, a prevalência das práticas da polifarmácia e automedicação e consumo de medicamentos impróprios estiveram dentro da média nacional.
