What Is Cannabidiol? Its Uses & Amp; Pharmacology


Cannabidiol is the predominant phytocannabinoid, which accounts for 40% of plant extracts of the cannabis plant.

CBD does not appear as any intoxicating effect caused by tetrahydrocannabinol (THC) in marijuana but may have an indeterminate effect on latent thinking and anxiety.

Medical uses


Unethical reports and preliminary studies suggested that CBD may be of value in treating epilepsy, but the quality of the studies was too poor to draw definitive conclusions. The 2014 Cochran Review included four randomized controlled trials, but all were of poor quality. CBD gained orphan drug status in the United States for the treatment of Dravet syndrome, a rare form of obsolete epilepsy. Plans are underway to conduct a double-blind, randomized study of CBD in Dravet syndrome and other treatment-resistant epilepsy.

Dreat syndrome (aka myoclonic epilepsy of pediatric or SMEI) is a rare form of epilepsy that begins in childhood and is difficult to treat. Some cannabis/hemp extract preparations with CBD are marketed as dietary supplements and the efficacy of a claim against Dewett syndrome. One such preparation is marketed under the name trademark Charlotte Web Hemp extracts. GW Pharmaceuticals is seeking FDA approval to prepare a liquid form of plant-derived CDB purified under the Trade Unit Epidiox (99% cannabidiol and less than 0.10% 9 9) as a treatment for Dravet syndrome. Epidiox was given a fast-track status and after positive results for the drug in late-onset trials. Hemp seed oil which a rich source of CBD can be extracted easily by cold pressing the hemp seeds.

Available forms

Nabixymoles (USN, trade name Cetexx) is an aerosolized smear for oral administration that maintains a 1: 1 ratio to CBD and THC. The drug was approved by Canadian authorities in 2005 to reduce the pain associated with multiple sclerosis. Epidiox, as an active pharmacological component of cannabidiol, attained orphan drug status in the United States in July 2015 for the treatment of Dravet syndrome.

Epidiox, oil from the cannabis plant prepared to undergo clinical trials for a refractory epilepsy syndrome, is prepared.

Adverse effects

The safety of CBD in humans has been studied in several small studies, suggesting that it tolerates well at doses of 1500 mg/day (PAO) or 30 mg (IV). A daily dose of CBD (700 mg) for 6 weeks did not induce any toxicity in patients treated for Huntington’s disease.


There is preclinical evidence to suggest that cannabidiol may decrease the clearance of THC, generally increasing plasma concentrations of THC resulting in more THC being available to receptors, which increases the effect of THC in a dose-dependent manner. is. Despite this, there is no significant effect of CBD on THC plasma levels from available evidence in humans.


Cannabidiol has very little affinity for the cannabinoid CB1 and CB2 receptors but acts as an indirect antagonist of these receptors. This may increase the effect of THC through increasing CB1 receptor density or through another CB1 receptor-related mechanism. Cannabidiol may also extend the duration of the effects of THC through inhibition of cytochrome P450, CYP3A, and CYP2C enzymes.

Cannabidiol has been found to act as an antagonist of GPR55, the G protein-coupled receptor and cannabinoid receptor expressed in the catabolic nucleus and putamen in the brain. This 5-HT1A receptor has also been shown to act as a partial agonist, and this action may be involved in the antidepressant, unresponsiveness, and neuroprotective effects of cannabidiol. It is an allosteric neuromotor of μ- and δ-opioid receptors as well. The pharmacological effects of cannabidiol have additionally accounted for pARTIP agonism and intracellular calcium release.

Research suggests that CBD may exert some of its pharmacological actions through inhibition of fatty acid amide hydrolase (FAAH), leading to increased levels of endocannabinoids such as anandamide produced by the body.

All these properties listed above makes CBD of great use in a lot of things, a hemp plant can be used to produce anti-anxiety/ anti-depressants, it can be used to make hemp plastic which is a new type of plastic and is biodegradable. There have been researches on the benefits and side effects of consuming CBD but its not enough and therefore use of this compound remains illegal in the majority of countries across the world.

Although some countries like Canada and many states of The United States of America have made the medical use of marijuana (the plant with high concentration of CBD and low concentration of THC) legal.
