Avaliação do uso de medicamentos inapropriados para idosos e suas reações adversas.

Abstract

The elderly population is growing and brings with it an increase in comorbidities resulting from the aging process, making them much more fragile and susceptible to health problems and thus increasing the consumption of inappropriate medicines, which cause much more aggressive adverse reactions. The purpose of this study was to evaluate the use of inappropriate drugs in the elderly and the presence of adverse reactions, aiming to verify the relationship between these variables in elderly participants of the project "Actions for Aging with Quality of Life", which occurs In the Sports Complex of the University of Santa Cruz do Sul (UNISC). The study consists in the application of a self-administered questionnaire, the medicines used by the elderly being analyzed according to the criteria of Beers 2015, considering: drugs inappropriate for the elderly; Types of adverse reactions arising from the use of inappropriate medicines; Inappropriate medicines, which can be used with caution in the elderly. The data were analyzed by associating the variables adverse reactions and the use of drugs inappropriate for the elderly using the chi-square test (p<0,05) using SPSS software version 20.0 (StatisticalPackage for the Social Sciences 20.0). The prevalence of inappropriate drugs for the elderly was 81.5%. The most potentially inappropriate drugs used were hydrochlorothiazide (74.3%) followed by amitriptyline (9.5%), fluoxetine (8.1%) and diazepam (2.7%) acting on the central nervous system. Subsequently, 1.4% used Class III antiarrhythmic agents: amiodarone, central acting muscle relaxant: cyclobenxaprine, alpha blocker: doxazosin and platelet aggregation inhibitor: ticlipine. It was observed the need for the prescriber to be aware of the influence that an inappropriate drug for the elderly can exert on the elderly, in order to avoid inadequate prescription and generate possible adverse reactions.
