Cannabidiol-A friend or a foe?

Area of Science:

• Pharmacology and Therapeutics
• Dermatology
• Cannabinoid Research

Background:

• Cannabidiol (CBD), derived from Cannabis sativa, exhibits significant therapeutic potential including anti-inflammatory and antioxidant properties.
• Conventional administration routes (e.g., oral) face challenges like poor solubility, hepatic degradation, and erratic bioavailability.
• Transdermal delivery systems are emerging as a viable alternative for enhanced CBD bioavailability and targeted effects.

Purpose of the Study:

• To critically examine the transdermal administration of cannabidiol (CBD).
• To explore the skin's potential as a route for systemic CBD targeting.
• To provide insights into CBD's variable bioavailability and ADME profile based on administration methods.

Main Methods:

• Literature-based review and analysis of transdermal CBD delivery systems.
• Examination of strategies for enhancing skin penetration and systemic targeting of CBD.
• Compilation of absorption, distribution, metabolism, and excretion (ADME) data for CBD via different routes.

Main Results:

• Transdermal delivery systems present a promising strategy to overcome the limitations of conventional CBD administration.
• Skin offers potential for targeted systemic delivery, improving bioavailability compared to oral routes.
• CBD's bioavailability is significantly influenced by administration route and formulation, necessitating further research.

Conclusions:

• Transdermal CBD administration is a viable approach to enhance therapeutic efficacy and overcome bioavailability challenges.
• Further clinical research and standardized formulations are crucial due to the variable regulatory landscape and growing market.
• Understanding the endocannabinoid system and CBD's interaction is key for optimizing its therapeutic applications across different medical conditions.
