Cannabidivarin is a homolog of cannabidiol, with a well-established antiepileptiform profile in preclinical studies, both in vitro and in vivo animal models of epilepsy. The oral bioavailability of cannabidivarin is very low (about 6%) due to erratic absorption and first pass metabolism. After oral administration, the maximum plasma concentration of Cannabidivarin is rising in about three hours and the drug has a large volume of distribution, because of his link to protein plasma, being highly liposoluble, so CBDV can penetrate well to the brain. Cannabidivarin is also metabolized in the liver to 7-COOH and 6-OH metabolites, but the mechanism is also unknown. There is an ongoing phase II double-blind, placebo-controlled trial that is assessing the efficacy and safety of cannabidivarin in Children With Autism Spectrum Disorder (ASD).
