3.3 Mechanisms of CBDO absorption in the body
CBD can be absorbed through various mechanisms, depending on the route of administration. For oral administration, CBD undergoes gastrointestinal absorption, where it passes through the gut wall and enters the portal circulation. Sublingual administration allows for direct absorption into the bloodstream through the sublingual mucosa. Inhalation of CBD leads to rapid absorption through the lung alveoli, while topical application allows for localized absorption through the skin.
4. Distribution of CBDO

Distribution refers to the movement of CBD from the bloodstream to various tissues and organs throughout the body. It is influenced by factors such as blood flow, tissue permeability, and protein binding. Understanding the distribution of CBD is crucial in determining its target sites of action and potential therapeutic effects.
4.2 Processes involved in CBDO distribution within the body
CBD distributes widely throughout the body due to its lipophilic nature. It can cross various biological barriers, including the blood-brain barrier, placental barrier, and blood-cerebrospinal fluid barrier. CBD binds extensively to plasma proteins, such as albumin, which can influence its distribution and free fraction available for pharmacological activity.
4.3 Factors affecting CBDO distribution: protein binding, tissue affinity, etc.
Protein binding is a significant factor influencing CBD's distribution within the body. High protein binding can limit the concentration of free CBD available for interaction with target sites. Additionally, the affinity of CBD for different tissues and organs can also influence its distribution, as certain tissues may have a higher affinity for CBD compared to others.
5. Metabolism of CBDO

Metabolism refers to the enzymatic conversion of CBD into various metabolites. The primary site of CBD metabolism is the liver, where it undergoes extensive biotransformation before elimination from the body. Metabolism is a crucial aspect of CBD pharmacokinetics as it determines the duration of action, potential drug interactions, and the formation of active or inactive metabolites.
5.2 Enzymes Involved in CBDO Metabolism
The metabolism of CBD primarily involves the cytochrome P450 (CYP) enzyme system, particularly CYP3A4 and CYP2C19. These enzymes catalyze the oxidative metabolism of CBD, leading to the formation of metabolites that can have distinct pharmacological properties.
