In late June 2018, the Food and Drug Administration (FDA) approved Epidiolex for sale in the U.S. It is the first prescription drug derived from the marijuana plant. The drug is designed to treat seizures for two rare forms of epilepsy: Dravet Syndrome and Lennox-Gastaut Syndrome. “Fast-track” designation was given to the drug during its approval process because it was the first FDA approval of a drug for the treatment of patients with Dravet Syndrome.1 “Orphan drug” designation (special status given to a drug that treats a rare condition or disease) was also given to the drug for use as a treatment for both Dravet Syndrome and Lennox-Gastaut Syndrome.
