Microencapsulation techniques for developing cannabidiol formulations: a review.

Area of Science:

• Pharmacology and Pharmaceutical Sciences
• Biotechnology
• Natural Product Chemistry

Background:

• Cannabidiol (CBD), derived from Cannabis sativa L., exhibits therapeutic properties without psychoactive effects.
• CBD interacts with the endocannabinoid system, influencing mood, pain, and immune responses.
• Poor bioavailability and water solubility limit CBD's clinical efficacy and administration.

Purpose of the Study:

• To review various microencapsulation techniques for CBD.
• To analyze the advantages and limitations of different microencapsulation methods.
• To explore the implications for optimizing CBD formulations.

Main Methods:

• Comprehensive literature review of microencapsulation techniques for CBD.
• Analysis of published data on CBD microencapsulation methods.
• Evaluation of formulation optimization strategies.

Main Results:

• Microencapsulation significantly improves CBD's bioavailability and solubility.
• Various techniques like spray-drying, liposomal encapsulation, and nanoparticle formation are effective.
• Each method presents unique advantages and limitations regarding scalability, cost, and encapsulation efficiency.

Conclusions:

• Microencapsulation is a viable strategy to overcome CBD's formulation challenges.
• Optimized microencapsulated CBD formulations hold significant promise for enhanced therapeutic delivery.
• Further research is needed to refine methods for large-scale, cost-effective production.
