GW Pharmaceuticals is a British biopharmaceutical company known for its multiple sclerosis treatment product nabiximols (brand name, Sativex) which was the first natural cannabis plant derivative to gain market approval in any country. Another cannabis-based product, Epidiolex, was approved for treatment of epilepsy by the US Food and Drug Administration in 2018.
GW Pharmaceuticals was founded in 1998 by Doctors Geoffrey Guy and Brian Whittle. That year, they obtained a cultivation license from the United Kingdom Home Office and the MHRA, allowing the company to cultivate, possess and supply cannabis to conduct scientific research concerning medicinal uses of the plant.
Later that year, GW Pharmaceuticals entered into a contract with HortaPharm B.V., a cannabis research and development corporation based in Amsterdam. The company was founded by two expert horticulturists from California, Robert Connell Clarke and David Paul Watson, and grew and developed specialized strains of cannabis with permission from the Dutch government.
Nabiximols (trade name Sativex) is a botanical drug that is a cannabis extract, administered as a mouth spray; it was approved in the UK in 2010 as a treatment for multiple sclerosis (MS) patients to alleviate neuropathic pain, spasticity, overactive bladder, and other symptoms.
