acupuntura, dor musculoesquelética, mecanismos moleculares de ação farmacológicaAbstract
Introdução: A acupuntura é uma técnica milenar chinesa que utiliza a inserção de agulhas em pontos específicos para promover a melhora sintomática de diversos problemas de saúde. Dentre eles se destaca a dor musculoesquelética, que é diretamente responsável por altos índices de absenteísmo laboral e má qualidade de vida. O tratamento desse tipo de dor é convencionalmente feito por fármacos. Contudo, o uso de métodos não-farmacológicos, em especial a acupuntura, tem se mostrado eficaz na melhora deste sintoma. Os mecanismos de ação dessa abordagem ainda não são completamente compreendidos. O que aumenta o interesse no aprofundamento do tema. ; Objetivo: Compreender os mecanismos de ação responsáveis pela modulação da nocicepção na acupuntura ; Método: Trata-se de uma revisão narrativa na qual foi feita a busca computadorizada de artigos através de bases de dados PubMed, ScienceDirect e Scielo, até março de 2024; Resultado: As teorias acerca da regulação nociceptiva englobam diferentes potenciais meios de atuação como a regulação das vias ascendente e descendente da dor, liberação de purinas, produção de endorfinas, produção de mediadores inflamatórios e ativação do sistema endocanabinóide. Conclusão: Ainda não está completamente elucidado o mecanismo pelo qual a acupuntura oferece o controle álgico. Contudo, há confluência entre as diversas teorias que buscam explicar esse fenômeno. Levando a crer que há não um, mas vários mecanismos de ação promovidos pela acupuntura.
