Newest firstPurpose Glaucoma is a leading cause of irreversible blindness globally, primarily driven by elevated intraocular pressure (IOP). Still, some patients progress despite significant IOP lowering, potentially due to impaired ocular blood flow. This study aimed to evaluate the effects of dronabinol, a synthetic tetrahydrocannabinol derivative, on ocular blood flow in primary open-angle glaucoma (POAG) patients. Methods…
Open article record in new tab ↗Medicinal cannabis use is increasing worldwide, yet its impacts on driving safety in frequent users are not clearly understood. A more comprehensive understanding of the effects of THC on driving behaviour in frequent users is needed to guide drug driving policy and evidence-based advice for medicinal cannabis consumers. This study investigated the acute effects of orally ingested THC oil on medicinal cannabis use…
Lymphatic transport of drugs after oral administration is an important physiological process in highly lipophilic compounds, such as cannabidiol (CBD). The majority of lymphatic transport studies have been historically conducted in anesthetized rats. However, this animal model differs significantly from the humans regarding both anatomical and physiological features. The aim of this study was therefore to develop…
Background Chronic neuropathic pain (CNP) involves complex interactions between resident and peripheral immune cells, as well as modulation of the endocannabinoid system. Cannabis-based products have emerged as promising therapeutic options, but their effects on immune cells remain unclear. This study evaluated the effects of a cannabidiol (CBD)-enriched Cannabis sp. extract administered via the oral mucosa in a C…
Background Emerging evidence indicates that cannabidiol (CBD) may offer meaningful therapeutic benefits across neurological, pain, and psychiatric disorders. Cannabidiol is already approved for the treatment of pediatric epilepsy. Owing to its high lipophilicity, it is typically delivered in oil-based formulations to overcome the low oral bioavailability of pure CBD. However, pharmacokinetic (PK) and safety data r…
Hemp products [cannabis with ≤0.3% Δ9-tetrahydrocannabinol (Δ9-THC)] are federally legal, but few controlled experiments have explored drug test results, pharmacokinetics, or pharmacodynamics. Healthy adults (n = 60) self-administered 1.5 mL medium-chain triglyceride (MCT) oil containing 100 mg cannabidiol (CBD) and either 0, 0.5, 1, 2, 2.8, or 3.7 mg Δ9-THC (n = 10 per group). The study included an 8-hour acute d…
There has been a growing interest in the use of cannabinoids in horses in recent years. Several studies have reported on the pharmacokinetics of cannabidiol (CBD) in horses. However, cannabidiolic acid (CBDA) has received less attention, despite limited evidence suggesting clinically beneficial effects in other species. Horses were administered 3 mg/kg of CBD, 3 mg/kg of CBDA, and a placebo per os in a crossover d…
Background The use of cannabis during pregnancy is rising following its widespread legalization. Cannabidiol (CBD) is gaining popularity due to the public perception that it is safer than the psychoactive cannabis component Δ9-tetrahydrocannabinol (THC). However, while evidence underpins the harm of THC and cannabis smoke on fetal development, there is minimal research on the safety of CBD and oral cannabis. The c…
The two most extensively studied cannabinoids, cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC), are used for myriad conditions. THC is predominantly eliminated via the cytochromes P450 (CYPs), whereas CBD is eliminated through both CYPs and UDP-glucuronosyltransferases (UGTs). The fractional contributions of these enzymes to cannabinoid metabolism have shown conflicting results among studies. Physiologica…
Cannabidiol (CBD), a phytocannabinoid commonly isolated from chemotype III Cannabis sativa plants, is known for its therapeutic potential. However, comprehensive information on its bioavailability is still lacking. The key objective of this study was to investigate the impact of specific formulations on CBD delivery to the site of action and, in particular, the brain of experimental animals. As brain tissue is an…
Open article record in new tab ↗Background Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting voluntary muscle movement as well as cognitive and other behavioural domains at later disease stages. No effective treatment for ALS is currently available. Elevated neuroinflammation, oxidative stress and alterations to the endocannabinoid system are evident in ALS. The phytocannabinoid cannabidiol (CBD) has anti-i…
Cannabidiol (CBD) is a natural product isolated from the Cannabis sativa plant that was approved by the United States Food and Drug Administration (US FDA) for the treatment of resistant epilepsy. Despite its therapeutic potential, CBD's clinical application is limited by its poor aqueous solubility and low oral bioavailability. The primary aim of this research was to enhance the aqueous solubility and oral bioava…
Cannabidiol (CBD) is a non-psychoactive phyto-cannabinoid with numerous pharmacological potentials. CBD is a lipophilic drug with poor and varied bioavailability due to its low water solubility and extensive first-pass metabolism, and it is highly affected by the presence of food. A self-emulsifying drug delivery system (SEDDS) was developed to improve the aqueous solubility and oral bioavailability of CBD. The fo…
Background The mental health benefits of cannabidiol (CBD) are promising but can be inconsistent, in part due to challenges in defining an individual's effective dosage. In schizophrenia, alterations in anandamide (AEA) concentrations, an endocannabinoid (eCB) agonist of the eCB system, reflect positively on treatment with CBD. Here, we expanded this assessment to include eCBs alongside AEA congeners, comparing ph…
Cannabis and its major constituents, Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD), are being widely used to treat sleep disturbances. However, THC can cause acute cognitive and psychomotor impairment and there are concerns that driving and workplace safety might be compromised the day after evening use. Here, we examined possible 'next day' impairment following evening administration of a typical medicinal…
Background Distressing symptoms are common in advanced cancer. Medicinal cannabinoids are commonly prescribed for a variety of symptoms. There is little evidence to support their use for most indications in palliative care. This study aims to assess a 1:20 delta-9-tetrahydrocannabinol/cannabidiol (THC/CBD) cannabinoid preparation in the management of symptom distress in patients with advanced cancer undergoing pal…
This study aimed to assess the single-dose pharmacokinetics and tolerability of a cannabidiol (CBD) isolate in sunflower oil with escalating oral doses in eight healthy, purpose-bred cats. Eight cats were randomized into six dosing groups of four cats each. Cats were administered a single 2.5, 5, 10, 20, 40, or 80 mg/kg dose orally with at least a two-week washout in between doses. Behavior scoring, complete blood…
Many jurisdictions use point-of-collection (POC) oral fluid testing devices to identify driving under the influence of cannabis, indexed by the presence of Δ9 -tetrahydrocannabinol (THC), an intoxicating cannabinoid, in oral fluid. Although the use of the non-intoxicating cannabinoid, cannabidiol (CBD), is not prohibited among drivers, it is unclear whether these devices can reliably distinguish between CBD and TH…
β-Caryophyllene (BCP), a common constituent of many spice and food plants, is gaining increased attention due to recent research identifying numerous potential health benefits. Due to limited oral bioavailability observed in preclinical models, the described benefits of BCP may be maximized by using a suitable delivery system. Additionally, human pharmacokinetics (PK) remain unknown. This study evaluates the relat…
In recent years, the interest in cannabidiol (CBD) has increased because of the lack of psychoactive properties. However, CBD has low solubility and bioavailability, variable pharmacokinetics profiles, poor stability, and a pronounced presystemic metabolism. CBD nanoformulations include nanosuspensions, polymeric micelles and nanoparticles, hybrid nanoparticles jelled in cross-linked chitosan, and numerous nanosiz…
