Resumo
JUSTIFICATIVA E OBJETIVOS: A dor crônica é uma condição clínica que atinge parte importante da população brasileira e mundial, afetando significativamente a vida dessas pessoas. As propriedades medicinais da Cannabis vêm sendo exploradas por milênios, mas recentemente seu uso para alívio dos sintomas da dor crônica tem aumentado.
CONTEÚDO: Foi conduzida uma revisão sistemática com o objetivo de avaliar o uso de cannabis e seus derivados no manejo da dor crônica, analisando seus potenciais efeitos adversos e sua segurança. Para isso, foram utilizadas as seguintes bases de dados: PubMed, Embase, Cochrane Library e BVS, buscando estudos publicados nos últimos 5 anos, nos idiomas português, espanhol ou inglês, utilizando os descritores MeSH e termos livres relevantes. Foram incluídos ensaios clínicos randomizados, duplos-cegos, com pelo menos 10 participantes em cada braço de comparação e com no mínimo 2 semanas de intervenção. Após a triagem dos autores, foi procedida a análise quantitativa de 4 ensaios clínicos (586 pacientes), que foram analisados para os desfechos de: pacientes com redução da intensidade da dor 50% ou 30% em relação à linha de base, melhora na intensidade média da dor, descontinuidade devido a efeitos adversos, efeitos adversos graves e qualquer efeito adverso.
CONCLUSÃO: Não foram encontradas evidências de alta qualidade quanto à avaliação dos desfechos de eficácia, segurança ou de efeitos adversos relacionados ao uso de tratamentos derivados da cannabis no manejo de dor crônica, não podendo ser produzidas recomendações ou restrições nesses aspectos, ficando o uso dessas modalidades terapêuticas sujeito a análise individual.
