Consenso da Sociedadade Brasileira de Cefaleia (SBCe) para o tratamento profilático da migrânea episódica: parte I

Autoria SCIMAGO INSTITUTIONS RANKINGS

Resumo

A Sociedade Brasileira de Cefaleia (SBCe) nomeou um Comitê de Autores com o objetivo de estabelecer um consenso com recomendações sobre o tratamento profilático da enxaqueca episódica com base em artigos da literatura mundial e da experiência pessoal. A enxaqueca é um distúrbio subdiagnosticado e subtratado que acomete um bilhão de pessoas no mundo e mais de 30 milhões de brasileiros. É conhecido na comunidade médica de neurologistas e, sobretudo, dos especialistas em cefaleia, a necessidade de se divulgar o conhecimento sobre o tratamento profilático da enxaqueca. Com esta finalidade, aliada às necessidades de atualizações de drogas e de se aumentar o conhecimento sobre a doença em si (frequência, intensidade, duração, impacto e talvez a progressão da enxaqueca), foi elaborado este Consenso, com metodologia totalmente on-line, por 12 grupos que revisaram e escreveram sobre as categorias farmacológicas das drogas e, ao final, reuniram-se para a leitura e conclusão do documento. As classes de drogas estudadas para este Consenso foram: anticonvulsivantes, antidepressivos tricíclicos, anticorpos monoclonais do antipeptídeo relacionado ao gene da calcitonina (peptídeo relacionado ao gene da calcitonina — anti-CGRP), betabloqueadores, anti-hipertensivos, inibidores dos canais de cálcio, outros antidepressivos (inibidores seletivos de recaptação de serotonina, ISRSs, e antidepressivos de ação dual), outras drogas, e politerapia. O tratamento hormonal, bem como anti-inflamatórios e triptanas em esquema de profilaxia mínima (miniprofilaxia), será abordado em um capítulo próprio. As classes de drogas estudadas na parte I do Consenso foram: anticonvulsivantes, antidepressivos tricíclicos, anticorpos monoclonais anti-CGRP, e betabloqueadores.
