Pharmacokinetics of Non-Psychotropic Phytocannabinoids.

Abstract

Cannabinoids are widely recognized for their potential therapeutic effects, making them significant and valuable candidates for medical research and applications across various fields. This review aims to analyze the pharmacokinetics of Cannabidiol (CBD), Cannabigerol (CBG), and Cannabichromene (CBC), along with their corresponding acidic forms, Cannabidiolic acid (CBDA), Cannabigerolic acid (CBGA), and Cannabichromenic acid (CBCA). Among these cannabinoids, CBD is the most extensively studied. Nevertheless, research involving all the mentioned cannabinoids has shown that their pharmacokinetic parameters are highly variable, depending significantly on factors such as dose, formulation, route of administration, and diet. Furthermore, challenges such as brain penetration and first-pass metabolism have been highlighted. In conclusion, this review demonstrates significant progress in understanding the pharmacokinetics of non-psychotropic cannabinoids. However, it also underscores the need for further research, particularly on CBG, CBC, and their respective acidic forms, with the most significant gap being in clinical investigations. Expanding these studies is essential to facilitate their optimized use in medical treatments.
