OBJECTIVE To assess the use of potentially inappropriate medications among older adults. METHODS This is a population-based cross-sectional study with 1,451 older individuals aged 60 years or more in the city of Pelotas, State of Rio Grande do Sul, Brazil, in 2014. We have investigated the use of medications in the last 15 days. Using the Beers criteria (2012), we have verified the use of potentially inappropriate medications and their relationship with socioeconomic and demographic variables, polypharmacy, self-medication, and burden of disease. RESULTS Among the 5,700 medications used, 5,651 could be assessed as to being inappropriate. Of these, 937 were potentially inappropriate for the older adults according to the 2012 Beers criteria (16.6%). Approximately 42.4% of the older adults studied used at least one medication considered as potentially inappropriate. The group of medications for the nervous system accounted for 48.9% of the total of the potentially inappropriate medications. In the adjusted analysis, the variables female, advanced age, white race, low educational level, polypharmacy, self-medication, and burden of disease were associated with the use of potentially inappropriate medications. CONCLUSIONS It is important to known the possible consequences of the use of medication among older adults. Special attention should be given to the older adults who use polypharmacy. Specific lists should be created with more appropriate medications for the older population in the National Essential Medicine List. OBJETIVO Avaliar o uso de medicamentos potencialmente inadequados entre idosos. MÉTODOS Estudo transversal de base populacional com 1.451 idosos com 60 anos ou mais em Pelotas, RS, em 2014. Investigou-se o uso de medicamentos nos últimos 15 dias. Utilizando os critérios de Beers (2012), verificou-se a potencial inadequação dos medicamentos e sua relação com variáveis socioeconômicas e demográficas, polifarmácia, automedicação e carga de doença. RESULTADOS Dentre os 5.700 medicamentos utilizados, 5.651 puderam ser avaliados quanto à inadequação. Destes, 937 eram potencialmente inadequados para idosos segundo os critérios de Beers de 2012 (16,6%). Cerca de 42,4% dos idosos usaram no mínimo um medicamento considerado potencialmente inapropriado. O grupo de medicamentos para o sistema nervoso correspondeu a 48,9% do total de medicamentos potencialmente inadequados. Na análise ajustada, as variáveis sexo feminino, idade avançada, cor da pele branca, baixa escolaridade, polifarmácia, automedicação e carga de doença mostraram-se associadas ao uso de medicamentos potencialmente inadequados. CONCLUSÕES É importante que sejam bem conhecidas as possíveis consequências do uso de medicamentos entre idosos. Atenção especial deve ser dada aos idosos que fazem uso de polifarmácia. É necessário existir listas específicas com medicamentos mais adequados para uso em idosos na Relação Nacional de Medicamentos Essenciais.
