“The nonpsychoactive cannabinoid, cannabidiol (CBD), has great potential for the treatment of chronic and ‘breakthrough’ pain that may occur in certain conditions like cancer. To fulfill this goal, suitable noninvasive drug delivery systems need to be developed for CBD. Chronic pain relief can be best achieved through the transdermal route, whereas ‘breakthrough’ pain can be best alleviated with intranasal (IN) delivery. Combining IN and transdermal delivery for CBD may serve to provide patient needs-driven treatment in the form of a nonaddictive nonopioid therapy.
CONCLUSION:
The results of this study indicated that CBD could be successfully delivered through the IN and transdermal routes.”
