CBDV Cannabidivarin

What is CBDV?

Cannabidivarin (CBDV) is a non-psychoactive cannabinoid that will not cause the euphoric feeling of being “high.” It is found more prevalently in indica strains, specifically landrace indica strains, and strains that are lower in tetrahydrocannabinol (THC).

Like CBD, CBDV significantly reduces the frequency and severity of seizures. It also reduces or even eliminates nausea associated with several conditions, and helps to reduce inflammation throughout the body. CBDV is also beneficial in the treatment of pain and mood disorders. Effects & Benefits

Research has shown that CBDV is effective in the treatment of a variety of symptoms and conditions. Examples of conditions for which CBDV is particularly effective in providing symptom relief are listed below:

Cannabidivarin, also known as cannabidivarol or CBDV, is a non-psychoactive cannabinoid found within Medical Cannabis. It is one of over 100 cannabinoids identified from the Cannabis plant that can modulate the physiological activity of cannabis, or marijuana [3]. Compared to its homolog, Cannabidiol, CBDV is shortened by two methyl (CH2) groups on its side chain. Notably, both Cannabidiol and CBDV have demonstrated anticonvulsant activity in animal and human models and are demonstrating promising clinical trial results [2456]. Other cannabinoids with some evidence of anti-epileptic activity include Tetrahydrocannabivarin (THCV) and Δ9-tetrahydrocannabinolic acid.

While the primary components of cannabis, CBD and THC, have been shown to modulate many of their physiological effects through their binding to the cannabinoid-1 (CB1R) and cannabinoid-2 (CB2R) receptors, the investigational cannabinoids with anticonvulsant action mostly use mechanisms that do not involve these two endocannabinoid receptors.

The anti-epileptic activity of CBD and CBDV is thought to be modulated by their effects on transient receptor potential cation channel subfamily V member 1 (TRPV1), also known as the capsaicin receptor, which is a member of a large family of ion channels that are involved in the onset and progression of several types of epilepsy. CBD and CBDV have been shown to dose-dependently activate and then desensitize TRPV1 as well as TRPV2 and TRPA1 channels [478]. Desensitization of these ion channels is a potential mechanism by which these molecules cause a reduction of neuronal hyperexcitability that contributes to epileptic activity and seizures.

CBDV has also been shown to inhibit the activity of diacylglycerol (DAG) lipase-α, the primary enzyme responsible for the synthesis of the endocannabinoid, 2-arachidonoylglycerol (2-AG) [110]. The clinical implications of this are unclear however, as this interaction has not been shown to affect CBDV's anticonvulsant activity.

Cannabidivarin is being actively developed by GW Pharmaceuticals as the experimental compound GWP42006 as it has "shown the ability to treat seizures in pre-clinical models of epilepsy with significantly fewer side effects than currently approved anti-epileptic drugs" [13]. Unfortunately, as of February 2018, GW Pharmaceuticals announced that their Phase 2a placebo-controlled study of CBDV for focal seizure did not reach its primary endpoints. They will continue to study its use in epilepsy, however, and are expanding their investigations to include its potential use in Autism Spectrum Disorder, Rett syndrome and Fragile X among others [12].

In October 2017 CBDV was given orphan designation by the European Medicines Agency for use in Rett Syndrome [15] and again in February 2018 for treatment of Fragile X Syndrome [14].
