terapia de reposição hormonal, câncer de mama, interações medicamentosas, tamoxifeno, farmacocinéticaResumo
A terapia de reposição hormonal (TRH) é amplamente utilizada para atenuar os sintomas do climatério, porém sua segurança em pacientes com histórico de câncer de mama permanece controversa, sobretudo devido ao risco de interações medicamentosas com fármacos antineoplásicos. Este estudo teve como objetivo realizar uma revisão sistemática da literatura para identificar, classificar e analisar as principais interações medicamentosas entre agentes utilizados na TRH e tratamentos empregados em pacientes com câncer de mama. A busca foi conduzida nas bases de dados PubMed, SciELO e LILACS, utilizando os descritores “Hormone Replacement Therapy”, “Breast Cancer” e “Drug Interactions”, combinados com os operadores booleanos AND e OR. Foram incluídos 50 estudos publicados entre 2002 e 2024, com base em critérios de elegibilidade pré-definidos. Os resultados demonstraram que o uso concomitante de TRH com fármacos como tamoxifeno, inibidores da aromatase e antidepressivos ISRS pode gerar interações farmacocinéticas e farmacodinâmicas relevantes, especialmente por modulação enzimática via citocromo P450. A via de administração, o tipo hormonal e o tempo de exposição também influenciam diretamente no risco oncológico. Conclui- se que o uso da TRH em pacientes com câncer de mama deve ser considerado apenas em situações específicas, com avaliação individualizada e acompanhamento multiprofissional rigoroso, diante dos potenciais riscos de interação medicamentosa e implicações clínicas.
