An Overview of Cannabidiol as a Multifunctional Drug: Pharmacokinetics and Cellular Effects

/by

Cannabidiol (CBD), a non-psychoactive compound derived from Cannabis Sativa, has garnered increasing attention for its diverse therapeutic potential. This comprehensive review delves into the complex pharmacokinetics of CBD, including factors such as bioavailability, distribution, safety profile, and dosage recommendations, which contribute to the compound’s pharmacological profile. CBD’s role as a pharmacological inhibitor is explored, encompassing interactions with the endocannabinoid system and ion channels. The compound’s anti-inflammatory effects, influencing the Interferon-beta and NF-κB, position it as a versatile candidate for immune system regulation and interventions in inflammatory processes. The historical context of Cannabis Sativa’s use for recreational and medicinal purposes adds depth to the discussion, emphasizing CBD’s emergence as a pivotal phytocannabinoid. As research continues, CBD’s integration into clinical practice holds promise for revolutionizing treatment approaches and enhancing patient outcomes. The evolution in CBD research encourages ongoing exploration, offering the prospect of unlocking new therapeutic utility.

Delta-8-Tetrahydrocannabinol: A Phytocannabinoid on the Rise

/by

Delta-8-tetrahydrocannabinol (THC) is a minor psychoactive phytocannabinoid, similar to delta-9-tetrahydrocannabinol. Recent statements released by the FDA and CDC reported around 660 delta-8-THC exposure cases. With the rise in commercially available products, it is crucial to understand the pharmacological and toxicological properties of this compound. The objective of this review is to summarize current literature regarding the pharmacokinetic, and pharmacologic properties of delta-8- THC.

Cannabidiol for the Treatment of Brain Disorders: Therapeutic Potential and Routes of Administration

/by

The use of cannabidiol (CBD) for treating brain disorders has gained increasing interest. While the mechanism of action of CBD in these conditions is still under investigation, CBD has been shown to affect numerous different drug targets in the brain that are involved in brain disorders. Here we review the preclinical and clinical evidence on the potential therapeutic use of CBD in treating various brain disorders. Moreover, we also examine various drug delivery approaches that have been applied to CBD. Due to the slow absorption and low bioavailability with the current oral CBD therapy, more efficient routes of administration to bypass hepatic metabolism, particularly pulmonary delivery, should be considered. Comparison of pharmacokinetic studies of different delivery routes highlight the advantages of intranasal and inhalation drug delivery over other routes of administration (oral, injection, sublingual, buccal, and transdermal) for treating brain disorders. These two routes of delivery, being non-invasive and able to achieve fast absorption and increase bioavailability, are attracting increasing interest for CBD applications, with more research and development expected in the near future.

Scientific Validation of Cannabidiol for Management of Dog and Cat Diseases

/by

Cannabidiol (CBD) is a non-psychotropic phytocannabinoid of the plant Cannabis sativa L. CBD is increasingly being explored as an alternative to conventional therapies to treat health disorders in dogs and cats. Mecha- nisms of action of CBD have been investigated mostly in rodents and in vitro and include modulation of CB1, CB2, 5-HT, GPR, and opioid receptors. In companion animals, CBD appears to have good bioavailability and safety profile with few side effects at physiological doses. Some dog studies have found CBD to improve clinical signs associated with osteoarthritis, pruritus, and epilepsy. However, further studies are needed to conclude a therapeu- tic action of CBD for each of these conditions, as well as for decreasing anxiety and aggression in dogs and cats. Herein, we summarize the avail- able scientific evidence associated with the mechanisms of action of CBD, including pharmacokinetics, safety, regulation, and efficacy in ameliorating various health conditions in dogs and cats.
