RESUMO
OBJETIVO:
Identificar o perfil de uso de medicamentos no primeiro trimestre de gravidez com ênfase na avaliação da segurança e na adoção do ácido fólico e do sulfato ferroso por gestantes em uma Unidade Básica de Saúde da região Sul do Brasil.MÉTODOS:
Trata-se de estudo transversal aninhado a uma coorte de gestantes. Os medicamentos foram classificados segundo a Anatomical Therapeutic Chemical (ATC), e a segurança avaliada segundo a Food and Drug Administration (FDA) e a Agência Nacional de Vigilância Sanitária (ANVISA). Foi investigado o uso/prescrição de sulfato ferroso e ácido fólico segundo o protocolo do Ministério da Saúde.RESULTADOS:
Foram incluídas 212 gestantes. Dessas, 46,7% estavam em uso de medicamentos no momento do diagnóstico da gravidez e 97,6% utilizaram medicamentos no primeiro trimestre gestacional. O percentual mais elevado de automedicação ocorreu antes do início do pré-natal (64,9%). Observou-se maior exposição a medicamentos de risco D e X, segundo a classificação do FDA, antes do início do pré-natal (23,0%). Entre as gestantes, 32,5% não seguiam o protocolo de uso de ácido fólico e sulfato ferroso do Ministério da Saúde. No total, 67,9% das gestantes tiveram exposição inadequada aos medicamentos. Houve diferença entre as proporções de medicamentos utilizados segundo a ATC, e os principais grupos anatômicos identificados foram os dos medicamentos que atuam no sangue e órgãos hematopoiéticos e anti-infecciosos de uso sistêmico. Na época do diagnóstico da gravidez, observou-se expressivo uso de medicamentos que atuam no sistema geniturinário e hormônios sexuais (16,2%), como anticoncepcionais orais, o que provavelmente está relacionado ao percentual ...ABSTRACT
PURPOSE:
To identify the profile of use of medication during the first trimester of pregnancy with emphasis on safety assessment and on the adoption of folic acid and ferrous sulfate by pregnant women attended at a Basic Health Unit in Brazil.METHODS:
This was a cross-sectional study nested in a cohort of pregnant women. Medications were classified according to the Anatomical Therapeutic Chemical (ATC), and their safety was evaluated according to the Food and Drug Administration (FDA) and the Brazilian Health Surveillance Agency (ANVISA). The adoption of ferrous sulfate and folic acid was investigated according to the protocol set forth by the Brazilian Ministry of Health.RESULTS:
The survey included 212 pregnant women, 46.7% of whom were taking medications at the time of pregnancy diagnosis, and 97.6% used medication during the first trimester after diagnosis. The highest percentage of self-medication occurred before the beginning of prenatal care (64.9%). According to the FDA criteria, there was a high level of exposure to D and X risk drugs before the beginning of prenatal care (23.0%), which was also observed for drugs not recommended by ANVISA (36.5%). Of the surveyed sample, 32.5% did not follow the protocol of the Brazilian Ministry of Health. In all, 67.9% of pregnant women had inadequate drug exposure. There was a difference between the proportions of drugs used according to the ATC, and the main anatomical groups identified were the drugs that act on blood and blood-forming organs, and anti-infective medications for systemic use. When pregnancy was diagnosed, the use of a large number of medications that act on the genitourinary system and sex hormones (16.2%) was identified, such as oral contraceptives, a fact probably related to the percentage of unplanned pregnancies (67.0%), on the same occasion 4 pregnant women used folic acid and 3 used ferrous sulphate.CONCLUSION:
The present results show that a large number ...Key words
