Transdermal Cannabidiol Patch Sustained Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drug delivery systems for cannabidiol, particularly for chronic pain and inflammation, face challenges such as psychoactive side effects, gastric irritation, and variable plasma concentrations with oral administration, necessitating an improved transdermal delivery method that provides sustained release and reduced dosing frequency without peak and trough effects.
Innovation Solution
A transdermal delivery system using synthetic cannabidiol in various forms, including free base, salts, and derivatives, formulated into patches or formulations that provide continuous release over several days, minimizing skin irritation and allowing self-administration with adjustable dosing frequency, thereby avoiding systemic peaks and troughs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If oral administration of cannabidiol is used to treat chronic pain and inflammation, then therapeutic effect is achieved, but psychoactive side effects and gastric irritation occur
Solution Approach 1:
The patent uses the skin and transdermal delivery system as an intermediary route between the drug and systemic circulation, avoiding direct contact with the gastrointestinal tract and first-pass metabolism. This mediator (transdermal patch) delivers cannabidiol through the skin into bloodstream, achieving therapeutic effects while bypassing the harmful interactions with the stomach and reducing psychoactive side effects associated with oral administration.
2Reliability
If oral administration of cannabidiol is used, then pain relief is achieved, but variable plasma concentrations with peak and trough effects occur
Solution Approach 1:
The transdermal patch provides continuous, sustained release of cannabidiol through the skin over an extended period (typically 24 hours or more). This continuous delivery mechanism maintains stable plasma concentrations by constantly supplying the drug at a controlled rate, eliminating the peak and trough fluctuations that occur with intermittent oral dosing, thereby ensuring consistent pain relief.
3Reliability
If frequent dosing is used to maintain therapeutic levels, then pain control is improved, but patient compliance and ease of operation deteriorate
Solution Approach 1:
The transdermal patch is applied in advance and provides prolonged therapeutic coverage without requiring frequent patient intervention. A single patch application maintains therapeutic cannabidiol levels for 24 hours or more, allowing patients to prepare ahead and reducing the burden of frequent dosing, thereby improving compliance while maintaining effective pain control.

AI summary
Provided is a transdermal drug delivery system comprising cannabidiol, or a cannabidiol salt alone or in combinations thereof. Transdermal delivery can provide a drug plasma concentration at predetermined rate for a predetermined period of time with a simplified therapeutic regimen by decreasing dosing frequency for the treatment and/or prevention of pain and/or inflammation.
