Cannabidiol from Conventional to Advanced Nanomedicines for the Management of Cancer-Associated Pain

Chemotherapy-induced pain is one of the major challenges that hamper the patient's quality of life. Several cases of insufficient pain management were reported globally, especially in the case of patients who do not respond well to conventional pain management regimes and opioid analgesics. Additionally, conventional pain management has several shortcomings, and evidence suggests that cannabidiol has the potential to overcome those shortcomings. Cannabidiol (CBD) is a non-psychoactive compound of the Cannabis plant that shows an effective outcome in chemotherapy- induced pain as well as in cancer treatment, as it possesses anti-inflammatory and analgesic properties. The mechanism of pain and its management by cannabidiol, with all possible evidence, is well summarised in the paper. This article concludes the types of pain experienced by cancer patients, the effectiveness of CBD in the management of pain, and challenges faced by patients after using Cannabidiol with various case studies. Later, antitumor efficacy studies of CBD were disclosed, and its various types of formulations and nano-formulations were summarized in the paper. Overall, the paper establishes the role of cannabidiol in Chemotherapy-induced pain.
