Judicialização em saúde e atuação defensorial em caso de insumo não incorporado: a demanda de Canabidiol na Defensoria Pública Federal de Salvador/BA durante a última década / Health judicialization and the role of Public Defender's Office in a case of non-standardized input: the demand for Cannabidiol at the Federal Public Defender's Office in Salvador/Ba over the past decade / Judicialización sanitaria y acción de la Defensoría Pública en un caso de insumo no incorporado: la demanda de Cannabidiol en la Defensoría Pública Federal de Salvador/Ba em la última década

Objetivo: avaliar a atuação da Defensoria Pública Federal e a efetividade da juridificação da saúde, como instrumento para garantia de acesso ao direito, no caso de insumo não padronizado (Canabidiol), na unidade de Salvador/Bahia. Metodologia: estudo descritivo com aplicação de método longitudinal retrospectivo das demandas de Canabidiol que chegaram à unidade, desde o caso índice admitido no país em 2014, com evolução anual e destino, na instituição e na Justiça, até 2023. Resultados: houve crescimento sistemático dos pedidos, que dobraram anualmente, sobretudo a partir de 2018, exceto no ano de 2021, totalizando 88 casos. O percentual de pleitos judicializados foi de 59%, e, dentre eles, mais da metade obteve decisão liminar favorável em alguma instância, alcançando 76% nas sentenças de mérito. O tempo entre a chegada do requerente, reunião de documentos e propositura da ação foi, em média, de 2,4 meses, e o intervalo médio entre o protocolo da peça inicial e a intimação da antecipação de tutela, nos casos em que concedida, foi de 2 meses. O intervalo entre a intimação da decisão antecipatória e o efetivo cumprimento foi em torno de 9,2 meses, somente obtido mediante bloqueio judicial em quase 70% dos casos. Conclusão: a atuação defensorial se mostrou célere, tão logo reunidos os documentos necessários, bem como as liminares concedidas. O tempo de cumprimento após a decisão concessiva mostrou intervalo alargado, evidenciando uma nova forma de inefetividade do direito social à saúde, o que a judicialização visava exatamente a combater.

Objective: to evaluate the performance of the Federal Public Defender's Office and the effectiveness of the juridification of health, as an instrument to guarantee access to the right, in the case of a non-standardized input (Cannabidiol), in the Salvador/Bahia unit. Methodology: a descriptive study with application of retrospective longitudinal method was carried out on the number of Cannabidiol claims that have reached the unit since the index case admitted in Brazil in 2014, its annual evolution and destination in the institution and in the court, until 2023. Results and discussion: there was a systematic growth in the number of cases, which doubled annually, especially from 2018 onwards, except in 2021. The percentage of judicialized lawsuits was about 59%, and, among those, more than half obtained a favorable decision in some instance, reaching 76% from the merit sentences. The time between the arrival of the applicant, the gathering of documents and the filing of the action was, on average, 2.4 months, and the average interval between the filing of the initial petition and the intimation of the anticipation decision, in the cases where it was granted, was 2 months. On the other hand, the interval between the intimation of the anticipatory decision and the effective compliance oscillated around 9.2 months, only being obtained through judicial blocking in almost 70% of the cases. Conclusion: it was found that the defense was swift, as soon as the necessary documents were gathered, as well as the injunctions granted. On the other hand, the time of compliance after the concession decision showed an alarmingly long interval, resulting in a new form of ineffectiveness of the social right to health, which the judicialization aimed precisely to combat.

Objetivo: evaluar el desempeño de la Defensoría Pública Federal y la efectividad de la juridificación de la salud, como instrumento para garantizar el acceso al derecho, en caso de insumo no estandarizado (Cannabidiol), en la unidad de Salvador/Bahía. Metodología: se realizó un estudio descriptivo con aplicación del método longitudinal retrospectivo sobre los reclamos de Cannabidiol que han llegado a la unidad desde el caso índice admitido en el pays, en 2014, su evolución anual y destino, en la institución y en los tribunales, hasta 2023. Resultados y discusión: hubo un aumento sistemático en el número de solicitudes, que se duplicaron anualmente, especialmente a partir de 2018, a excepción de 2021. El porcentaje de demandas fue de alrededor del 59% y, entre los judicializados, más de la mitad obtuvo una decisión favorable en alguna instancia, llegando al 76% en las sentencias de mérito. El tiempo promedio entre la llegada del demandante, la recopilación de documentos y la presentación de la demanda fue de 2.4 meses, y el intervalo promedio entre la presentación de la petición inicial y la decisión de anticipación, en los casos en que fue concedida, fue de 2 meses. Por otro lado, el intervalo entre la intimación de la decisión anticipada y el cumplimiento efectivo osciló en torno a los 9,2 meses, obteniéndose únicamente a través del bloqueo judicial en casi 70% de los casos. Conclusión: se comprobó que la defensoría fue rápida, tan pronto como se reunieron los documentos necesarios, así como las medidas cautelares otorgadas, después de escuchado el órgano de soporte técnico. Por otro lado, el tiempo de cumplimiento posterior a la decisión de concesión mostró un intervalo alarmantemente largo, lo que resultó en una nueva forma de ineficacia del derecho social a la salud, que la judicialización pretendía precisamente combatir.

Evaluation of the efficacy and safety of cannabidiol-rich cannabis extract in children with autism spectrum disorder: randomized, double-blind, and placebo-controlled clinical trial

Abstract Objective Autism spectrum disorder (ASD) is characterized by persistent deficits in social communication and social interaction and by restricted and repetitive patterns of behavior. Some studies have shown that substances derived from Cannabis sativa improve the quality of life of children with ASD without causing serious adverse effects, thus providing an alternative therapeutic option. The objective of this study was to evaluate the efficacy and safety of a cannabis extract rich in cannabidiol (CBD) in children with ASD. Methods In this randomized, double-blind, placebo-controlled clinical trial, 60 children, aged from 5 to 11 years, were selected and divided into two groups: the treatment group, which received the CBD-rich cannabis extract, and the control group, which received the placebo. They both used their respective products for a period of 12 weeks. Statistical analysis was done by two-factor mixed analysis of variance (two-way ANOVA). Results Significant results were found for social interaction (F1,116 = 14.13, p = 0.0002), anxiety (F1,116 = 5.99, p = 0.016), psychomotor agitation (F1,116 = 9.22, p = 0.003), number of meals a day (F1,116 = 4.11, p = 0.04), and concentration (F1,48 = 6.75, p = 0.01), the last of which was only significant in mild ASD cases. Regarding safety, it was found that only three children in the treatment group (9.7%) had adverse effects, namely dizziness, insomnia, colic, and weight gain. Conclusion CBD-rich cannabis extract was found to improve one of the diagnostic criteria for ASD (social interaction), as well as features that often co-exist with ASD, and to have few serious adverse effects.

Use of cannabis and its derivates in chronic pain management: systematic review / Uso de cannabis e seus derivados no manejo da dor crônica: revisão sistemática

ABSTRACT BACKGROUND AND OBJECTIVES: Chronic pain is a clinical condition that affects an important part of the Brazilian and world population, significantly affecting their lives. The medicinal properties of Cannabis have been explored for millennia, but recently its use for the relief of chronic pain symptoms has increased. CONTENTS: A systematic review was carried out with the objective of evaluating the use of cannabis and its derivatives in the management of chronic pain, analyzing its potential side effects and safety. For this, the following databases were used: Pubmed, Embase, Cochrane Library and BVS, searching for studies published in the last 5 years, in Portuguese, Spanish or English, using MeSH descriptors and relevant free terms. Randomized, double-blind clinical trials with at least 10 participants in each comparison arm and with at least 2 weeks of intervention were included. After screening the authors, a quantitative analysis of 4 clinical trials (586 patients) was performed, which were analyzed for the outcomes of: patients with 50% or 30% reduction in pain intensity compared to baseline, improvement in pain intensity average pain, discontinuation due to adverse effects, serious adverse effects, and any adverse effects. CONCLUSION: The analysis did not yield high-quality evidence pertaining to the evaluation of efficacy, safety, or adverse effects associated with the use of cannabis-derived treatments in the management of chronic pain. Consequently, the formulation of recommendations or restrictions in these regards is not feasible, leaving the utilization of these therapeutic modalities subject to individual assessment.

El objetivo de la presente revisión narrativa fue analizar y sintetizar la información disponible acerca de las posibilidades terapéuticas actuales del cannabis en odontología y sus perspectivas futuras. Materiales y métodos: Se realizó una búsqueda electrónica que abarcó artículos hasta diciembre del 2022, en las bases de datos MEDLINE, Scopus, Scielo y Google Académico. Se utilizaron las siguientes palabras claves principales: "dental", "dentistry", "cannabis", "cannabinoids", "benefits", "therapeutics", "treatment", "potential". En las búsquedas iniciales se encontraron un total de 834 registros. Se evaluó la elegibilidad de 45 artículos de texto completo. Se incluyeron 35 estudios para el análisis cualitativo de la presente revisión. Resultados: Los estudios muestran gran variedad de cannabinoides y derivados empleados, preparados comerciales, así como preparados experimentales. Se han llevado adelante estudios in vitro, in vivo y clínicos que evalúan la acción de los cannabinoides en el control del dolor orofacial, de la inflamación, como cicatrizante, en la regeneración del tejido óseo, como antimicrobiano y su capacidad anticancerígena. Conclusiones: Los cannabinoides han demostrado potencial en el tratamiento de diversas condiciones y/o alteraciones bucales. Aún la estandarización de los productos y protocolos de tratamiento es insuficiente por los que son necesarios más estudios que evalúen presentaciones, derivados, métodos de extracción, concentraciones y vías de administración.

Introduction: The interest in using cannabis and cannabinoids as a therapeutic tool has gained relevance in medicine in recent years. In line with this, interest in its study has increased in dentistry. The aim of the present narrative review was to analyze and synthesize the available information about the current therapeutic possibilities of cannabis in dentistry and its future perspectives. Materials and methods: an electronic search conducted that included articles until December 2022, in the MEDLINE, Scopus, Scielo and Google Scholar databases. The following main keywords used: "dental," "dentistry," "cannabis," "cannabinoids," "benefits," "therapeutics," "treatment," "potential." A total of 834 records founded in the first searches. Forty-five full-text articles assessed for eligibility. Thirty-five studies included for the qualitative analysis of the present review. Results: Studies show a great variability of cannabinoids and derivatives used, including commercial preparations, as well as experimental preparations. In vitro, in vivo, and clinical studies had conducted evaluating the action of cannabinoids in the control of orofacial pain, as anti-inflammatory and healing, in bone tissue regeneration, as antimicrobial and evaluating their anti-cancer ability. Conclusions: Cannabinoids have shown potential in the treatment of various oral conditions and/or disorders. Even the standardization of products and treatment protocols is insufficient, which is why more studies are necessary to evaluate presentations, derivatives, extraction methods, concentrations, and routes of administration for their best use.

Beneficio clínico del tratamiento con cannabinoides para el dolor crónico no oncológico

Introducción: los cannabinoides pueden ser una opción válida para el tratamiento del dolor crónico no oncológico de acuerdo a los estudios publicados hasta el momento y a nuestra experiencia clínica. Objetivo: valorar el beneficio clínico de preparados de cannabis medicinal (CM) para dolor crónico no oncológico en pacientes que consultaron en la Clínica de Endocannabinología del Uruguay (CEDU). Material y método: estudio descriptivo, observacional, longitudinal, de una población atendida en un centro privado de salud. Se trata de una cohorte de 438 pacientes que consultaron espontáneamente en CEDU desde septiembre de 2016 a marzo de 2020. El motivo de consulta fue dolor crónico no oncológico que no respondió al tratamiento estándar. Resultados: en la cohorte estudiada predominaron las mujeres (74%), promedio 69 años, que se asisten en el sistema privado de salud en el 95% de los casos, en su mayoría con instrucción secundaria. El tipo de dolor más frecuente fue el dolor osteoarticular. El quimiotipo de CM más usado fue cannabidiol (CBD) al 5%, con buena respuesta al tratamiento en el descenso del nivel del dolor y suspensión o disminución de uso de opioides (y derivados) y antiinflamatorios no esteroideos (AINES). Se observaron escasos y leves efectos adversos (EA) en la gran mayoría de los pacientes. Abandonaron el tratamiento 12 pacientes (menos del 3%). Conclusiones: esta investigación retrospectiva mostró una caída del nivel del dolor de 3,14 (valor p ≤ 0,0001), indicando que el CM puede ser una opción para el tratamiento del dolor crónico no oncológico. Se requieren más estudios para demostrar la efectividad y seguridad de los cannabinoides. Esto depende de muchos factores (leyes que faciliten la accesibilidad a variedad de productos de CM de grado médico, incentivos a la ciencia e investigación). De todas formas, podemos afirmar que los resultados presentados son prometedores en relación con su potencial terapéutico.

Introduction: Cannabinoids can be a valid option for the treatment of chronic non-cancer pain, according to the studies published to date and our clinical experience. Objectives: To evaluate the clinical benefit of medicinal cannabis preparations (MCPs) for chronic non-cancer pain in patients seen at the Endocannabinology Clinic of Uruguay (CEDU). Method: Descriptive, observational, longitudinal study of a population treated at a private healthcare center. This involves a cohort of 438 patients who spontaneously consulted at CEDU from September 2016 to March 2020. The reason for consultation was chronic non-cancer pain that did not respond to standard treatment. Results: in the studied cohort, women prevailed and accounted for 74% of patients. Average age was 69 years old and 95% of them sought care within the private healthcare system. Most women had completed secondary school education. The most frequent type of pain was osteoarticular pain. The most used chemovar of Medicinal Cannabis (MC) was 5% cannabidiol (CBD), showing a favorable treatment response in reducing pain levels and the discontinuation or reduction of opioid and non-steroidal anti-inflammatory drug (NSAID) usage. Few and mild adverse effects (AE) were observed in the vast majority of patients. Twelve patients (less than 3%) discontinued the treatment. Conclusions: This retrospective study demonstrated a reduction in pain level of 3.14 (p-value ≤ 0.0001) indicating that MC could be an option for the treatment of non-oncological chronic pain. Further studies are needed to demonstrate the effectiveness and safety of cannabinoids. This depends on many factors (laws facilitating accessibility to a variety of medical-grade MC products, incentives for science and research). Nevertheless, we can assert that the presented results are promising in consideration of their therapeutic potential.

Isso depende de muitos fatores (leis que facilitem o acesso a uma variedade de produtos CM de grau médico, incentivos para ciência e pesquisa). De qualquer forma, podemos afirmar que os resultados apresentados são promissores em relação ao seu potencial terapêutico.

Cannabis: Drug of Abuse and Therapeutic Agent, Two Sides of the Same Coin

ABSTRACT The consumption of Cannabis sativa plant, known as marijuana in the Western world, for different purposes (therapeutic, intoxicating, and spiritual) due to its psychoactive effects, can be traced back to ancient times. Cannabis is the most used illicit drug worldwide; however, its legal status is changing rapidly. Cannabis regulation will allow a better understanding of its effects as a misused drug, including new challenges, such as the availability of highly potent Cannabis extracts. Furthermore, scientific research is making significant efforts to take advantage of the potential therapeutic uses of Cannabis active compounds. The science of Cannabis derivatives started with the identification of the phytocannabinoids Δ9-tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD), allowing the formal study of the complex set of effects triggered by Cannabis consumption and the deciphering of its pharmacology. Δ9-THC is recognized as the compound responsible for the psychoactive and intoxicating effects of Cannabis. Its study led to the discovery of the endocannabinoid system, a neuromodulatory system widespread in the human body. CBD does not induce intoxication and for that reason, it is the focus of the search for cannabinoid potential clinical applications. This review examines the current state of knowledge about contrasting perspectives on the effects of Cannabis, Δ9-THC, and CBD: their abuse liability and potential therapeutic use; two sides of the same coin.

Uso de cannabidiol para el control de síntomas refractarios en síndromes convulsivos y enfermedades neurodegenerativas / Use of cannabidiol for the control of refractory symptoms in convulsive syndromes and neurodegenerative diseases

Como parte de las terapias alternativas para el control de síntomas refractarios en enfermedades avanzadas destaca el uso de cannabidiol. Este se ha estudiado en patologías como enfermedad de Alzheimer, Parkinson y trastornos convulsivos. Los síndromes convulsivos están presentes en todos los grupos etarios. Dentro de este, la epilepsia es refractaria hasta en un 40 % de los pacientes, quienes han demostrado disminución en la frecuencia de convulsiones con el uso concomitante de cannabidiol y antiepilépticos convencionales, con efectos secundarios leves, como diarrea y somnolencia. Con el objetivo de determinar el uso del cannabidiol para el control de síntomas neurológicos refractarios en pacientes con síndromes convulsivos y enfermedades neurodegenerativas, se realizó una búsqueda bibliográfica en Pubmed, Scopus y Embase. Se incluyeron metaanálisis, artículos originales, revisiones sistemáticas y bibliográficas, y documentos de la Organización Panamericana de la Salud, publicados entre 2017 y 2022. Los efectos del cannabidiol lo convierten en una alternativa, adicional a la terapéutica convencional, para el control de síntomas en trastornos neurológicos, disminuyendo de forma sostenida el número total de episodios con un perfil de seguridad aceptable. Existe limitada información respecto al uso de cannabidiol en enfermedades neurodegenerativas, por lo que no se ha evidenciado su efectividad

As part of the alternative therapies for the control of refractory symptoms in advanced diseases, the use of cannabidiol stands out. It has been studied in pathologies such as Alzheimer's disease, Parkinson's disease, and convulsive disorders. Convulsive syndromes are present in all age groups. Within this group, epilepsy is refractory in up to 40 % of patients, who have shown a decrease in the frequency of seizures with the concomitant use of cannabidiol and conventional antiepileptics, with mild side effects such as diarrhea and drowsiness. To determine the use of cannabidiol for the control of refractory neurological symptoms in patients with seizure syndromes and neurodegenerative diseases, a literature search was performed in PubMed, Scopus, and Embase. Meta-analyses, original articles, systematic and literature reviews, and documents from the Pan American Health Organization, published between 2017 and 2022, were included. The effects of cannabidiol make it an alternative, in addition to conventional therapeutics, for symptom control in neurological disorders, sustainably decreasing the total number of episodes with an acceptable safety profile. There is limited information regarding the use of cannabidiol in neurodegenerative diseases, the reason its effectiveness has not been demonstrated.

Indications for the use of cannabinoids / Indicação do uso de canabinoides

ABSTRACT BACKGROUND AND OBJECTIVES: The increasingly widespread use of cannabinoids in the management of acute and chronic pain generates an urgent need to study how cannabinoids act on CB1 and CB2 receptors and what their effects are on the organism. It is important to understand the difference in action between natural cannabinoids (cannabidiol, delta 9-tetrahydrocannabinol, cannabigerol, cannabinoil, terpenes) and synthetic ones, so that the appropriate choice is made in each case, and depending on the pathophysiology of pain, one or the other active is more indicated. CONTENTS: Studies collected in the Pubmed, Cochrane Library and Web of Science databases were analyzed. These studies focus were on natural cannabinoids (cannabidiol, delta 9-tetrahydrocannabinol, cannabigerol, cannabinoil, terpenes) and synthetic cannabinoids in the use for the treatment of chronic pain, their action on the endocannabinoid system through the activation of the CB1 and CB2 receptor and their effect after activating this receptor, aiming to compile which cannabinoid is more indicated in the treatment of pain pathology. CONCLUSION: The subject still requires much study and new articles are being published daily. The analysis of the studies must be carried out with criteria to evaluate their seriousness. The endocannabinoid system is closely linked to the treatment of chronic pain and some cannabinoids such as: cannabidiol, delta 9-tetrahydrocannabinol, cannabigerol, cannabinoil, as well as some terpenes are already considered important in the treatment of chronic pain inferring sparing effect of opioids, anticonvulsants, antidepressants among others.

RESUMO JUSTIFICATIVA E OBJETIVOS: O uso cada vez mais disseminado dos canabinoides no controle da dor aguda e crônica gera uma necessidade urgente do estudo de como os canabinoides agem nos receptores CB1 e CB2 e quais seus efeitos no organismo. É importante entender a diferença de ação entre os canabinoides naturais (canabidiol, delta 9-tetrahidrocanabinol, canabigerol, canabinol, terpenos) e os sintéticos, para que a escolha adequada seja realizada em cada caso, sendo que dependendo da fisiopatologia da dor é mais indicado um ou outro ativo. CONTEÚDO: Foram analisados estudos coletados na Pubmed, Cochrane Library e Web of Science. Os estudos se concentram em canabinoides naturais (canabidiol, delta 9-tetrahidrocanabinol, canabigerol, canabinoil, terpenos) e canabinoides sintéticos no uso para o tratamento da dor crônica, sua ação no sistema endocanabinoide através da ativação do receptor CB1 e CB2 e seu efeito após ativar esse receptor, visando compilar qual canabinoide é mais indicado no tratamento da patologia álgica. CONCLUSÃO: O assunto ainda requer muito estudo e diariamente novos artigos vem sendo publicados. A análise dos estudos deve ser realizada com critério para avaliar sua seriedade. O sistema endocanabinoide está intimamente ligado ao tratamento da dor crônica e alguns canabinoides como: canabidiol, delta 9-tetrahidrocanabinol, canabigerol, canabinoil, assim como alguns terpenos já são considerados importantes no tratamento da dor crônica inferindo efeito poupador de opioides, anticonvulsivantes, antidepressivos entre outros.

Cannabinoids for the treatment of autism and childhood epilepsy / Canabinoides no tratamento do autismo e epilepsia infantil

ABSTRACT BACKGROUND AND OBJECTIVES: Epilepsy and autism spectrum disorder (ASD) are diseases with neuropsychiatric impairment, which, depending on their clinical presentation, can be treated with medical cannabis. The objective of this work is to present a brief review of the literature on the use of cannabinoids (CNB) in the management of ASD and epilepsy. CONTENTS: The elaboration of this review was made from search and selection. Searches were carried out in the following databases: LILACS, Medline via Pubmed, Scielo and Cochrane Library, published from January 2010 to December 2022. CONCLUSION: The use of CNB, both for epilepsy and for ASD, has been shown to be safe, however actual effectiveness has yet to be proven.

RESUMO JUSTIFICATIVA E OBJETIVOS: A epilepsia e o transtorno do espectro do autismo (TEA) são doenças com comprometimento neuropsiquiátrico, os quais, dependendo da sua apresentação clínica, podem ser tratados com a cannabis medicinal. O objetivo deste estudo foi apresentar uma breve revisão da literatura sobre o uso de canabinoides (CNB) no manejo do TEA e da epilepsia. CONTEÚDO: A elaboração desta revisão foi feita a partir de busca e seleção. Foram realizadas buscas nas bases de dados: LILACS, Medline via Pubmed, Scielo e Cochrane Library, publicados no período de janeiro de 2010 a dezembro de 2022. CONCLUSÃO: O uso dos CNB, tanto para epilepsia quanto para o TEA, tem se mostrado seguro, porém a real eficácia ainda não foi comprovada.

The endocannabinoid system and orofacial pains: updates and perspectives / O sistema endocanabinoide e as dores orofaciais: atualidades e perspectivas

ABSTRACT BACKGROUND AND OBJECTIVES: Since the relatively recent discovery of the endocannabinoid system (ECS) and its fundamental role in regulating other systems, the subject has aroused interest in all areas of health, including Dentistry. Among the possible uses and benefits of cannabinoids are their performance in pain and its predisposing or perpetuating factors, such as bruxism and sleep disorders. Although the literature is still scarce, the mechanisms of action and satisfactory results of cannabinoids and other cannabis derivatives in these situations already allow their safe prescription. The objective of this study was to verify the current evidence on the use of cannabis derivatives in orofacial pain (OFP), reviewing what is known, to date, about the ECS and the prospects for its use with support and criteria. CONTENTS: This research carried out a brief review of the cannabis plant history, addressing issues such as prejudice, prohibitions and interests, as well as its therapeutic use. Then, a review on ECS and its mechanisms of interest in OFP was presented. Next, the products derived from the plant and their effects, indications, contraindications, adverse effects, drug interactions, peculiarities and perspectives were discussed. CONCLUSION: The more knowledge is gained about the ECS and the therapeutic benefits of cannabis components and derivatives, the greater the conviction that a new therapeutic frontier has indeed emerged. The growing number of good outcomes, including cases of OFP, obtained through well-conducted studies, brings a mixture of satisfaction and excitement. No therapy will achieve good results if it does not start from an accurate diagnosis. Thus, it is of the utmost importance to know the ECS, the products and derivatives of the plant, the synthetic cannabinoids, their indications and effects. New studies are necessary and, at this moment, it can be said that the perspectives are very good and a new and challenging horizon is emerging.

RESUMO JUSTIFICATIVA E OBJETIVOS: Desde a descoberta relativamente recente do sistema endocanabinoide (SEC) e seu papel fundamental da regulação de outros sistemas, o assunto tem despertado interesse de todas as áreas da saúde, incluindo-se a Odontologia. Dentre as possíveis utilizações e benefícios dos canabinoides, está sua atuação na dor e seus fatores predisponentes ou perpetuadores, como o bruxismo e os distúrbios do sono. Embora a literatura seja ainda escassa, os mecanismos de ação e resultados satisfatórios dos canabinoides e demais derivados da cannabis nessas situações já permitem sua prescrição com segurança. O objetivo deste estudo foi verificar as atuais evidências sobre a utilização de derivados da cannabis nas dores orofaciais (DOFs), revisando o que se sabe, até o momento, sobre o SEC e as perspectivas de sua utilização com respaldo e critério. CONTEÚDO: Esta pesquisa realizou uma breve revisão da história da planta cannabis, abordando temas como preconceito, proibições e interesses, além de sua utilização terapêutica. Em seguida, foi apresentada uma revisão sobre o SEC e seus mecanismos de interesse na DOF. Na sequência, foram discutidos os produtos derivados da planta e seus efeitos, indicações, contraindicações, efeitos adversos, interações farmacológicas, peculiaridades e perspectivas. CONCLUSÃO: Quanto mais são adquiridos conhecimentos sobre o SEC e os benefícios terapêuticos dos componentes e derivados da cannabis, mais há um convencimento de que surgiu, de fato, uma nova fronteira terapêutica. O número crescente de bons desfechos, incluindo casos de DOF, obtidos através de estudos bem conduzidos, traz um misto de satisfação e empolgação. Nenhuma terapia obterá bons resultados se não partir de um diagnóstico preciso. Assim, é de suma importância que se conheça o SEC, os produtos e derivados da planta, os canabinoides sintéticos, suas indicações e efeitos. Novos estudos são necessários e, nesse momento, pode-se afirmar que as perspectivas são muito boas e um novo e desafiador horizonte está despontando.

Judicialização de produtos à base de canabidiol no Brasil: uma análise de 2019 a 2022 / Judicialization of cannabidiol-based products in Brazil: an analysis from 2019 to 2022 / Judicialización de productos a base de cannabidiol en Brasil: un análisis de 2019 a 2022

Este estudo analisou as ações judiciais de pacientes que solicitaram ao Sistema Único de Saúde produtos à base de canabidiol (CBD) durante o período de 2019 a 2022, descrevendo características sociodemográficas, clínicas e jurídicas. Trata-se de um estudo transversal composto pela avaliação das notas técnicas emitidas pelos Núcleos de Apoio Técnico do Judiciário (NatJus), que embasaram as decisões judiciais. Os dados foram obtidos do sistema e-NatJus, do Ministério da Justiça, utilizando técnicas de web scraping. Regressão logística foi empregada para estimar razões de chances com intervalos de 95% de confiança. Foram analisadas 1.115 notas técnicas das ações demandantes de CBD, das quais 54,7% dos pacientes eram do sexo masculino, com idade média de 18,4 anos, em sua maioria da Região Sul do país (38,8%), e 49,6% buscavam tratamento para epilepsia. Das ações com pareceres favoráveis, 28,8% não tinham evidências científicas, 26,5% pleitearam produtos sem registro na Agência Nacional de Vigilância Sanitária e 25,3% dos que tinham registro não estavam em conformidade com a indicação terapêutica. Os pacientes da Região Nordeste tiveram a chance de parecer favorável aumentada em 3 vezes; e os que tinham diagnóstico de epilepsia, em 2,3 vezes. Os pareceres técnicos que deram suporte aos magistrados para as decisões judiciais das demandas de pacientes por produtos à base de canabidiol no Brasil estavam, em sua maioria, em conformidade com evidências científicas, denotando a importância dos NatJus na qualificação do acesso a produtos medicinais no país.

The study analyzed the lawsuits of patients who requested cannabidiol (CBD)-based products from the Brazilian Unified National Health System during the period from 2019 to 2022, describing sociodemographic, clinical, and legal characteristics. This is a cross-sectional study composed of the evaluation of the technical notes issued by the Center for Technical Support of the Judiciary (NatJus), which supports judicial decisions. The data were obtained from the e-NatJus system, of the Brazilian Ministry of Justice, using web scraping techniques. Logistic regression was used to estimate odds ratios with 95% confidence intervals. We analyzed 1,115 technical notes of the CBD plaintiffs, of which 54.7% of the male patients, with a mean age of 18.4 years, mostly from the South Region of the country (38.8%), and 49.6% sought treatment for epilepsy. Regarding the actions with favorable opinions, 28.8% had no scientific evidence, 26.5% pleaded for products without registration with the Brazilian Health Regulatory Agency, and 25.3% of those that had registration were not in compliance with the therapeutic indication. Patients from the Northeast Region had a chance of a favorable opinion increased by 3.0 times and those diagnosed with epilepsy by 2.3. The expert opinions that supported the magistrates for the judicial decisions regarding the demands of patients for cannabidiol-based products in Brazil were mostly in accordance with scientific evidence, denoting the importance of NatJus in the qualification of access to medicinal products in the country.

Cannabis recreativo: Perfil de los cannabinoides presentes en muestras de marihuana suministradas por población consumidora / Recreational cannabis: Profile of cannabinoids present in marijuana samples supplied by the consuming population

RESUMEN El cannabis o marihuana es una de las sustancias psicoactivas más consumida en todo el mundo, por lo que conocer la composición y el tipo de cannabis que se comercializa en los entornos urbanos es un insumo necesario para el diseño de políticas en salud pública sustentadas en la evidencia científica. Este estudio caracterizó los principales fitocannabinoides de muestras de marihuana (cigarrillos o cogollos) obtenidas en áreas urbanas y rurales de la ciudad Medellín, en octubre de 2021. Se realizó un muestreo no probabilístico a conveniencia en el que se recolectaron 87 muestras de marihuana donadas por consumidores en diferentes puntos de recolección en toda la ciudad, aplicando las técnicas de cromatografía de gases masas e ionización de llama para la caracterización de los fitocanabinoides. Se encontró el tetrahidrocannabinol como el constituyente principal de la marihuana circulante en Medellín, donde el 67,8% de las muestras presentaba un rango toxicológico alto o superior para THC; lo anterior en un contexto donde el mercado desregulado limita la posibilidad que tienen los consumidores en la práctica de calibrar o decidir la concentración de cannabinoides en sus dosis.

ABSTRACT As cannabis/marijuana is one of the most consumed psychoactive substances in the world, knowing the composition and type of cannabis sold in urban environments is a necessary input for the design of public health policies based on scientific evidence. This study characterized the main phytocannabinoids of marijuana samples (cigarettes or buds) obtained in urban and rural areas of the city of Medellín in October 2021. Non-probabilistic convenience sampling was carried out in which 87 marijuana samples donated by consumers were collected at different collection points throughout the city, and gas chromatography-mass spectrometry and flame ionization techniques were employed for the characterization of phytocannabinoids. Tetrahydrocannabinol (THC) was found to be the main constituent of circulating marijuana in Medellín, where 67.8% of the samples had a high or higher toxicological range for THC; the foregoing in a context where the deregulated market in practice limits the possibility that consumers have to calibrate or decide the concentration of cannabinoids in their doses.

Abstract Objective: The aim of this current report was to present a critical review of the use of cannabidiol (CBD) in the treatment of refractory epilepsies in the pediatric population. Data source: Literature review was carried out in the Medline (PubMed), Cochrane, and Scientific Electronic Library Online (SciELO) databases with the descriptors "Cannabidiol" and "Epilepsy." The search was not limited by the date of publication, language, or study design. A total of 69 articles were included in the review. Data synthesis: The efficacy of CBD in treating epileptic seizures has been confirmed by randomized controlled trials for Lennox-Gastaut syndrome, Dravet syndrome, and tuberous sclerosis complex. The incidence of side effects reported in subjects of the studies is high. However, most studies indicate a good safety profile and tolerance to the drug, with most of the adverse effects being mild to moderate and transient. Conclusions: There is no consensus on the release of CBD as a therapeutic tool by the drug regulatory agencies worldwide. However, the use of CBD is promising since it has presented satisfactory results in crisis control in well-designed studies. In addition, this drug has a good safety and tolerance profile. However, further studies with a long follow-up period are needed to confirm its usefulness and the long-term safety in pediatric patients.

Neuropathies and the use of cannabinoids as a therapeutic strategy / Neuropatias e o uso de canabinoides como estratégia terapêutica

ABSTRACT BACKGROUND AND OBJECTIVES: Prevalence of painful neuropathy is around 7%-10% in the entire population, also, it may have different histories and require integrated care. Challenges for patient care are concerning, most of them have not achieved satisfactory results with drugs for pain management, which are often disabling, in addition to associated comorbidities such as sleep disorders and mood swings. Most of the drugs currently being used for neuropathic pain (NP) have several adverse effects, which hinders adherence to treatment and makes it impossible to reach the doses that would be indicated for proper management. Given this scenario, studies are being done aiming at the endocannabinoid system present in the human body with the ability to modulate pain, sleep, and mood disorders, among other benefits. Drugs such as phytocannabinoids, mainly the molecules cannabidiol (CBD) and tetrahydrocannabidiol (THC), have been studied with significant potential for the treatment of painful neuropathy. This review aimed to describe the probable mechanisms of action of cannabinoids in NP and the results obtained so far with the use of these molecules. CONTENTS: This study is a narrative review of the literature. Data were analyzed using the databases National Library of Medicine (NCBI), Academic Google, Medline and scientific database configurations by LILACS and Web of Science in a temporal search between 2004 and 2022. A total of 45 articles were counted. CONCLUSION: THC modulates opioid effects in neuropathic pain. This is associated with a pharmacokinetic effect and has also been demonstrated by brain imaging. This significant performance can be associated with specific target sites and primary actors regarding Δ-9-THC and its binding to receptors associated with analgesia. Also, further studies with this component or associated with small cannabinoid variations are necessary to certify its role in neuropathic pain.

RESUMO JUSTIFICATIVA E OBJETIVOS: A neuropatia dolorosa tem prevalência estimada em toda a população em torno de 7% a 10%, pode ter diversas etiologias e requer cuidado integrado. O cuidado desses pacientes costuma ser desafiador, pois a maioria deles não obtém resultados satisfatórios com os fármacos disponíveis para manejo da dor que, muitas vezes, são incapacitantes, além das comorbidades associadas, como distúrbios do sono e alterações de humor. A maioria dos fármacos utilizados atualmente para o tratamento da dor neuropática (DN) apresenta diversos efeitos adversos, o que dificulta a adesão ao tratamento e impossibilita atingir as doses que seriam indicadas para o manejo adequado. Diante desse cenário, estudos estão sendo feitos visando o sistema endocanabinoide presente no corpo humano, que tem capacidade de modular a dor, sono e distúrbios do humor, entre outros benefícios. Fármacos como os fitocanabinoides, principalmente com as moléculas canabidiol (CBD) e tetrahidrocanabidiol (THC), têm sido estudados com potencial significativo para o tratamento da neuropatia dolorosa. Esta revisão teve o objetivo de descrever os mecanismos prováveis de ação dos canabinoides na DN e os resultados obtidos até o momento com a utilização dessas moléculas. CONTEÚDO: Este estudo é uma revisão narrativa da literatura. Os dados foram analisados utilizando as bases de dados National Library of Medicine (NCBI), Google acadêmico, Medline e configurações de bases científicas pela LILACS e Web of Science em uma busca temporal entre 2004 e 2022. Foram contabilizados 45 artigos. CONCLUSÃO: O THC modula os efeitos opioides na dor neuropática. Esta atuação é associada com efeito farmacocinético e foi demonstrada por imagens cerebrais. Esta atuação significativa pode ser associada com sítios alvo específicos e atuantes primários com relação ao Δ-9-THC e sua ligação a receptores associados à analgesia. Entretanto, mais estudos com este componente ou associado a pequenas variações canabinoides são necessários para afirmar a sua atuação na dor neuropática.

Integrative approach to the therapeutic use of cannabis for orofacial pain / Abordagem integrativa do uso terapêutico da cannabis nas dores orofaciais

ABSTRACT BACKGROUND AND OBJECTIVES: Faced with the difficulty of treating chronic orofacial pain and seeking an approach that aims at the health and well-being of the patient in a broader way, cannabinoid therapy appears as an adjunct to pharmacological approaches. CONTENTS: Cannabinoid therapy generates analgesia through the activation of the endocannabinoid system, as well as the use of palmitoylethanolamide (PEA), curcumin, grape seed extract, aromatherapy, acupuncture, laser therapy and the practice of physical exercise. In this way, these therapies allow a reduction in the use of analgesic drugs. CONCLUSION: Cannabinoid therapy is part of this integrative approach and the combination of cannabinoids with other forms of activation of the endocannabinoid system contributes to a better therapeutic outcome and a better quality of life for countless patients suffering from chronic orofacial pain.

RESUMO JUSTIFICATIVA E OBJETIVOS: Diante da dificuldade de tratamento das dores orofaciais crônicas e buscando uma abordagem que vise a saúde e o bem-estar do paciente de uma forma mais ampla, surge a terapia canabinoide como coadjuvante nas abordagens farmacológicas. CONTEÚDO: A terapia canabinoide promove analgesia através da ativação do sistema endocanabinoide, assim como o uso da palmitoiletanolamida (PEA), curcumina, extrato de semente de uva, aromaterapia, acupuntura, laserterapia e a prática de exercício físico. Desta forma, essas terapias permitem redução do uso de fármacos analgésicos. CONCLUSÃO: A terapia canabinoide faz parte dessa abordagem integrativa e a combinação dos canabinoides com outras formas de ativação do sistema endocanabinoide contribui para melhores resultados terapêuticos e melhor qualidade de vida para inúmeros pacientes que sofrem de dores orofaciais crônicas.

Neuroprotective potential of cannabidiol: Molecular mechanisms and clinical implications / 中西医结合学报

Cannabidiol (CBD), a nonpsychotropic phytocannabinoid that was once largely disregarded, is currently the subject of significant medicinal study. CBD is found in Cannabis sativa, and has a myriad of neuropharmacological impacts on the central nervous system, including the capacity to reduce neuroinflammation, protein misfolding and oxidative stress. On the other hand, it is well established that CBD generates its biological effects without exerting a large amount of intrinsic activity upon cannabinoid receptors. Because of this, CBD does not produce undesirable psychotropic effects that are typical of marijuana derivatives. Nonetheless, CBD displays the exceptional potential to become a supplementary medicine in various neurological diseases. Currently, many clinical trials are being conducted to investigate this possibility. This review focuses on the therapeutic effects of CBD in managing neurological disorders like Alzheimer's disease, Parkinson's disease and epilepsy. Overall, this review aims to build a stronger understanding of CBD and provide guidance for future fundamental scientific and clinical investigations, opening a new therapeutic window for neuroprotection.

Experimental acute anti-inflammatory activity of preparations with complexed cannabidiol in carriers

Abstract Cannabidiol (CBD) is a bioactive compound with promising anti-inflammatory results but has low aqueous solubility. Complexation of drugs with this characteristic in carriers is an alternative to improve their efficiency. This study aimed to prepare and characterize CBD complexes in different carriers, and to evaluate the anti-inflammatory effect of such preparations using an experimental model of edema induction in rat paws. The results were compared to a reference drug, ibuprofen (IBU). The carriers evaluated were beta cyclodextrin (bCD) and activated charcoal (AC). Quantification of the drugs in the complexes was determined, and different qualitative analyses were also performed. Oral treatments in single doses with CBD showed inhibitory effects similar to that of IBU, potentiating its bioactivity without significant adverse effects. CBD*bCD doses at 4.375, 8.75, 17.5, and 35 mg/kg significantly reduced the intensity of edema compared to equivalent doses of pure bioactive. In contrast, CBD*AC did not generate benefits. There was no significant inhibitory effect on myeloperoxidase activity, requiring more specific analyses to assess this parameter. The results suggest that the CBD*bCD complexation is perfectly feasible, increasing its anti-edematogenic efficacy in the experimental model used.
