AI Summary

Cannabidiol (CBD), a non-psychoactive compound from cannabis, is emerging as a promising candidate for treating glioblastoma multiforme (GBM)—one of the most aggressive and difficult-to-treat brain cancers. This review examines how CBD works at the molecular level to combat tumor growth, inhibit cancer cell proliferation, and make tumors more responsive to chemotherapy. The research highlights multiple mechanisms by which CBD interferes with tumor development, suggesting it could be valuable not just as a standalone therapy but also when combined with conventional cancer treatments.

The main challenge holding back CBD's clinical use is a practical one: the human body doesn't absorb it very well when taken by mouth. To overcome this limitation, scientists are developing advanced delivery systems using nanotechnology—essentially creating microscopic carriers that can transport CBD more effectively throughout the body and specifically to the brain where it's needed. These include nanoparticles, liposomes, nanoemulsions, and other lipid-based delivery systems that significantly improve how much CBD actually reaches tumor cells.

By combining CBD's therapeutic potential with smart delivery technology, researchers believe they may dramatically improve treatment outcomes for glioblastoma and other diseases. This synergistic approach could transform CBD from a promising compound into a practical medicine, potentially offering hope to patients with brain tumors where current treatments are often insufficient. The research underscores how nanotechnology and botanical compounds together might create more effective cancer therapies.

📄 Original Abstract

Cannabidiol (CBD), a nonpsychoactive phytocannabinoid extracted from Cannabis sativa, has emerged as a compound of considerable therapeutic interest across numerous medical disciplines, including pain management, anti-inflammatory therapy, and oncology. This review critically examines the potential of CBD in the treatment of glioblastoma multiforme (GBM), one of the most aggressive and treatment-resistant primary brain tumors. Particular emphasis is placed on the molecular mechanisms underlying CBD's antitumor activity, including the modulation of key signaling pathways, inhibition of tumor proliferation, and enhancement of chemosensitivity. Furthermore, the review highlights the increasing role of nanotechnology in overcoming the intrinsic pharmacokinetic limitations of CBD, particularly its low oral bioavailability, which presents a significant challenge to its clinical application. Advanced nanocarrier platforms, including nanoemulsions, nanoparticles, nanoparticle-based transdermal systems, nanocapsules, and liposomes, have shown promise in optimizing CBD delivery to the central nervous system (CNS). Notably, the integration of CBD into lipid-based drug delivery systems (LBDDS) is highlighted as a particularly promising strategy to potentiate its therapeutic efficacy. This approach enhances bioavailability and may amplify synergistic effects when combined with conventional chemotherapeutics or targeted agents. Overall, the synergistic use of nanotechnological approaches and CBD-based therapies may open new avenues for research, offering the potential to significantly advance treatment efficacy in glioblastoma and other diseases.
