Introduction: The fact of elderly people live in a greater amount with chronic diseases, make the elderly a great consumer of health services and, probably, the most medicated group in the society. In this context serious problems arise, such as the use of multiple medications simultaneously (polypharmacy) that can lead to serious consequences to the elderly health. Another problem is the self-medication, which may exacerbate the associated risks with prescript drugs, delaying a diagnosis and masking a disease. There is, still, the use of drugs considered inappropriate for elderly, either by reducing the therapeutic efficacy or an increased risk of adverse effects that increase the advantages in elderly usage. Objective: Analyzing the pattern of use of medications in aged people in the city of Goiânia-GO, and associate it with socioeconomic aspects and with the self-rated health. Methods: A population-based study and cross-section, that evaluated the health of elderly in the city of Goiânia-GO. The data collection was carried out in December/2009 to April/2010 from 934 elderly. The questionnaire had questions about medications, in addition to information about self-rated health and socioeconomic profile. The drugs groups were classified according to the Anatomical Therapeutic Chemical and Classification-ATC. The inappropriate drugs for elderly were identified according to Beers Criteria. Used Mann Whitney (U) and Chi-square test, it was considered significant p<0.05. Results: Among 934 elderly participants of the survey, 783 (83.8%) had answered completely to the questionnaire. These 738 elderly used 2846 drugs (3.63 drugs/elderly). Women consumed more medication than men (3.94 and 3.06 respectively, p <0.001). The most frequently consumed drugs act on the cardiovascular system (38.6%). The prevalence of polypharmacy was 26.4% and 35.7% of the elderly told to practise self-medication. The drugs most commonly used by self-medication were the painkillers (30.8%). According to Beers-Fick Criteria, 24.6% of the elderly used inappropriate drugs, 90.2% of these drugs came from a current prescription. The inappropriate drugs more consumed were benzodiazepines (34.2%). Women, widows, elderly with 80 years or more and those who had a worse self-rated health practiced more polypharmacy (p<0.05). Elderly people with lower education and with worse self-rated health practiced more self-medication (p<0.05). Conclusions: The results of this study showed that the pattern of drug use by elderly of Goiânia was similar to that found in elderly people from other regions of Brazil. Since the number of drugs used, the prevalence of polypharmacy and self-medication practices and the use of inappropriate drugs were within the national average. Women, widows, aged 80 years or more and those who consider their health as poor more often practiced polypharmacy, the largest self-medication was associated with a lower education and poorer self-rated health.
