Traditional treatments often face issues like delayed onset of action, systemic side effects, and challenges in achieving optimal drug concentrations at the target site. Intranasal drug delivery has emerged as a promising alternative for the management of cluster headaches due to its potential for rapid absorption and direct access to the central nervous system. Among the novel strategies under investigation, cubosome-based nanocarriers have gained significant attention due to their unique structural properties, biocompatibility, and ability to encapsulate a wide range of therapeutic agents. This review highlights recent advancements in intranasal delivery systems, focusing on cubosome-based nanocarriers for the treatment of cluster headaches. It explores the physicochemical characteristics of cubosomes that make them ideal for intranasal administration, including their high surface area, mucoadhesive properties, and ability to enhance drug stability and bioavailability. The review also examines the potential of cubosome-encapsulated verapamil, a calcium channel blocker, as a promising candidate for rapid and effective cluster headache relief. Furthermore, it addresses the challenges and future perspectives in the development and clinical translation of cubosome-based intranasal therapies. By synthesizing current research findings, this review aims to provide insights into the potential of cubosome-based nanocarriers as a transformative approach in the treatment of cluster headaches, paving the way for more effective, patient-friendly therapeutic options.
