Resumo

A enxaqueca crônica é uma patologia neurológica debilitante, caracterizada pela sensibilização do sistema trigeminovascular, que afeta a funcionalidade e a qualidade de vida de uma parcela significativa da população global. O objetivo do presente estudo foi analisar a eficácia da onabotulinumtoxinA (toxina botulínica tipo A) no tratamento profilático desta condição, com ênfase no papel estratégico do profissional biomédico. Realizou-se uma revisão integrativa da literatura (2016-2026) nas bases PubMed, SciELO, BVS e Cochrane, selecionando estudos que seguiram o protocolo PREEMPT. Os resultados demonstram que a neurotoxina atua via clivagem da proteína SNAP-25, inibindo a exocitose de neuropeptídeos nociceptivos (como o CGRP) e estabilizando o limiar de dor. Neste contexto, a atuação da biomedicina revela-se fundamental, pois a eficácia terapêutica depende diretamente do domínio ímpar da anatomia topográfica craniocervical para o mapeamento preciso das terminações sensoriais. O biomédico atua na gestão clínica avançada, aplicando o raciocínio farmacodinâmico para a execução segura do protocolo e adaptações posológicas focais (follow-the-pain). Conclui-se que a precisão técnica e o rigor anatômico inerentes à práxis biomédica são determinantes para a redução da morbidade, a mitigação de efeitos adversos e a melhoria da qualidade de vida dos pacientes refratários aos tratamentos convencionais.
