ABSTRACT

The definition of pain by the International Association for the Study of Pain (IASP), as revised in 2020, states that it is "an unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage," suggesting that pain or similar unpleasant sensory experiences may arise even if the cause of such sensations cannot be clearly identified. Pain, on the other hand, has been classified chronologically as acute, subacute or chronic pain such as those directly caused by cancer and non-cancer diseases and by the mechanisms involved. These are divided into nociceptive, neuropathic, and nociplastic pain, the last one of which is a recent addition to the classification. WHO created an independent category dedicated to chronic pain in its latest version of the International Classification of Diseases (ICD-11) defining it as pain that continues or reiterates over a period of three months or longer. As prolonged pain causes both physical and mental damage resulting in degradation of quality of life, it has been stressed that such pain must be approached from both the physical and mental perspectives. For this reason, multi-faceted evaluation is useful in treating chronic pain. In Japan, there are a number of guidelines for the treatment of chronic pain that have been published by different scientific societies as well as by a study group of the MHLW's Chronic Pain Policy Project. These serve as guides for providing evidence-based treatments to affected patients. Chronic pain remains a major challenge since they not only lower the quality of life of affected patients but also cause considerable damage to Japanese society as a whole.

ABSTRACT

ABSTRACT BACKGROUND AND OBJECTIVES: Evidence has revealed an important role in the use of medical cannabis, and the interaction of the endocannabinoid system with other drugs for the treatment of chronic neuropathic and nociplastic pain. The objective of this review is to bring an update on published data on doses and care with the use of cannabinoids that demonstrate the interaction in the pathophysiology of chronic pain and its treatment. CONTENTS: A research-based review was carried out in the MEDLINE, PUBMED database using the keywords "cannabis and pain", "endocannabinoid"; "neuropathic pain"; "nociplastic pain"; "drug interactions". CONCLUSION: Drug interaction with cannabinoids requires further scientific knowledge and doses are individual, which makes it difficult to create a protocol for treatment.


RESUMO JUSTIFICATIVA E OBJETIVOS: As evidências têm revelado um papel importante sobre o uso da cannabis medicinal e da interação do sistema endocanabinoide com outros fármacos para o tratamento de dor crônica neuropática e nociplástica. O objetivo deste estudo foi prover atualização sobre os dados publicados quanto a doses e cuidados com o uso dos canabinoides que mostrem interação na fisiopatologia da dor crônica e seu tratamento. CONTEÚDO: Foi realizada uma revisão baseada em pesquisa na base de dados Medline, Pubmed com uso dos unitermos "cannabis e dor", "endocannabinoid", "neuropathic pain", "nociplastic pain" e "drug interactions". CONCLUSÃO: A interação farmacológica com os canabinoides requer aprofundamento do conhecimento científico e as doses são individuais, o que dificulta a criação de um protocolo para tratamento.

ABSTRACT

ABSTRACT BACKGROUND AND OBJECTIVES: Nociplastic pain occurs due to a combination of hyperexcitability and decreased inhibitory activity in the central nervous system, responsible for a state of amplification of different stimuli, present in many chronic disorders. Among them: fibromyalgia, chronic migraine, irritable bowel syndrome, myofascial pain syndrome and complex regional pain syndrome. Often, several of these diseases are associated. Nociplastic pain therapy is a challenge in clinical practice, since most traditional treatments are not effective in controlling symptoms, often causing difficulty in adherence or even interruption of treatment due to undesirable adverse effects. The objective of this article was to demonstrate the importance of identifying the presence of nociplastic pain in the patient's condition, and also the pathophysiological mechanisms involved. Thus, due to retrograde neuromodulation, a unique feature of the endocannabinoid system until now, evaluate the use of pharmaceutical grade medicines based on the cannabis plant as an adjunct in the therapy of pain and other symptoms associated with this disorder. CONTENTS: This article was addressed the pathophysiology of nociplastic pain, the physiology to the endocannabinoid system, the cannabis plant with its components and its use as an adjuvant medication in the multimodal treatment of nociplastic pain (due to retrograde neuromodulation), based on published scientific articles between 1981 and 2022. CONCLUSION: Although the scientific evidence supporting the use of medical cannabis in nociplastic pain therapy is insufficient so far, it can and should be considered as a possible adjuvant medication in multimodal pain therapy, always on an individual basis, when recommended treatments fail or are not tolerated.


RESUMO JUSTIFICATIVA E OBJETIVOS: A dor nociplástica ocorre por uma combinação de hiperexcitabilidade e diminuição da atividade inibitória no sistema nervoso central, responsável por um estado de amplificação de estímulos diversos, presente em muitas doenças crônicas. Entre essas doenças estão: fibromialgia, migrânea crônica, síndrome do intestino irritável, síndrome dolorosa miofascial e síndrome de dor complexa regional. Frequentemente, várias dessas doenças se apresentam associadas. A terapia da dor nociplástica é um desafio na prática clínica, uma vez que a maioria dos tratamentos tradicionais não são eficazes no controle dos sintomas, causando muitas vezes dificuldade de adesão ou até mesmo interrupção do tratamento, devido aos efeitos adversos indesejáveis. O objetivo deste artigo foi demonstrar a importância da identificação da presença da dor nociplástica no quadro do paciente, e do conhecimento dos mecanismos fisiopatológicos envolvidos. Dessa forma, devido à neuromodulação retrógrada, característica exclusiva do sistema endocanabinoide até o momento, avaliar a utilização de fármacos de grau farmacêutico à base da planta cannabis como coadjuvante na terapia da dor e dos outros sintomas associados a essa doença. CONTEÚDO: Este artigo abordou a fisiopatologia da dor nociplástica, a fisiologia do sistema endocanabinoide, a planta cannabis com seus componentes e sua utilização como medicação coadjuvante no tratamento multimodal da dor nociplástica (decorrente da neuromodulação retrógrada), com base em artigos científicos publicados entre 1981 e 2022. CONCLUSÃO: Apesar das evidências científicas que apoiam o uso da cannabis medicinal na terapia da dor nociplástica serem insuficientes até o momento, ela pode e deve ser considerada como um possível fármaco coadjuvante na terapia multimodal da dor, sempre de forma individualizada, quando os tratamentos preconizados falharem ou não forem tolerados.

ABSTRACT

A fibromialgia é uma síndrome complexa com alterações nociplásticas, caracterizadas por hiperalgesia e alodinia, frequentemente acompanhada pela presença de dor orofacial. Estudos têm demonstrado alta prevalência de disfunção temporomandibular (DTM) em pacientes fibromiálgicos, como fator etiológico ou agravante. O objetivo desta revisão de literatura foi identificar os mecanismos modulatórios comuns à fibromialgia e à DTM, e identificar diferentes modalidades de tratamento para os pacientes fibromiálgicos. Foram utilizados 69 artigos dos últimos 5 anos, além de 4 artigos conceituais anteriores a este período. Identificou-se que os principais fármacos utilizados para os sintomas de fibromialgia são pregabalina, amitriptilina, antidepressivos duais, tramadol, baixas doses de naltrexona e canabinoides. A associação de fármacos pode ser útil para aumentar a eficácia do tratamento e reduzir as doses dos mesmos. Por outro lado, novas terapias não farmacológicas, como as técnicas modulatórias não-invasivas, surgem como opções promissoras, promovendo alterações neuroplásticas importantes no tratamento. Conclusão: Há diversas opções terapêuticas farmacológicas e não-farmacológicas disponíveis no tratamento do paciente fibromiálgico para o especialista em DTM. Portanto, a combinação de diferentes abordagens pode auxiliar na obtenção de um protocolo individualizado, adequado às necessidades do paciente.


Fibromyalgia is a complex syndrome with nociplastic changes, characterized by hyperalgesia and allodynia, often accompanied by the presence of orofacial pain. Studies have shown a high prevalence of temporomandibular disorders (TMD) in fibromyalgia patients, as an etiological or aggravating factor. The aim of this review was to identify the modulatory mechanisms common to fibromyalgia and TMD, and to identify different treatment modalities for fibromyalgia patients. 69 articles from the last five years were included, in addition to 4 conceptual articles prior to this date. The main drugs used for fibromyalgia symptoms are pregabalin, amitriptyline, dual antidepressants, tramadol, low-dose naltrexone and cannabinoids. The combination of drugs may be useful in improving treatment efficacy and for reducing the drug's dose. On the other hand, new non-pharmacological therapies, such as non-invasive modulatory techniques, appear as promising options for treatment, promoting important neuroplastic alterations. Conclusion: Several pharmacological and non-pharmacological therapeutic alternatives are available for specialists in TMD. Therefore, combining therapy approaches can help create individualized protocols that are more effective at meeting the demands of fibromyalgia patients.
