Abstract

This study aims to analyze the use of medicinal Cannabis sativa in the treatment of Dravet syndrome and Lennox-Gastaut syndrome, highlighting the main therapeutic benefits and the challenges related to its clinical application and regulation in Brazil. It is a bibliographic research, developed through the review of national and international scientific articles, health guidelines, and regulatory documents, providing a critical and well-founded approach to the subject. Dravet syndrome and Lennox-Gastaut syndrome are early-onset refractory epilepsies characterized by severe and hardto-control seizures, frequently resistant to conventional antiepileptic drugs. In this context, cannabidiol (CBD) has shown to be an effective therapeutic alternative, significantly reducing the frequency and intensity of seizures, as well as improving the quality of life of patients and their families. However, the use of medicinal cannabis still faces important obstacles, such as high costs, bureaucratic barriers, social stigma, and the lack of robust national studies to support its widespread implementation in the healthcare system. It is concluded that medicinal cannabis represents a relevant advancement in the management of refractory epilepsies, but its consolidation depends on greater investment in clinical research, updating of public policies, and training of healthcare professionals. Therefore, this study seeks to contribute to the academic and social debate on the subject, promoting reflections on the importance of science, ethics, and equity in access to innovative therapies.
