What is Sativex?
Sativex is a patented cannabinoid oromucosal mouth spray developed by the UK company GW Pharmaceuticals for multiple sclerosis (MS) patients, who can use it to alleviate neuropathic pain, spasticity, overactive bladder, and other symptoms.
Each spray delivers a near 1:1 ratio of CBD to THC, with a fixed dose of 2.7 mg THC and 2.5 mg CBD. Nabiximols is also being developed in Phase III trials as a potential treatment to alleviate pain due to cancer. It has also been researched in various models of peripheral and central neuropathic pain.
In May 2003 GW Pharmaceuticals and Bayer entered into an exclusive marketing agreement for GW’s cannabis-based medicinal extract product, to be marketed under the brand name Sativex. “Bayer has obtained exclusive rights to market Sativex in the UK. In addition, Bayer has the option for a limited period of time to negotiate the marketing rights in other countries in European Union and selected other countries around the world.”
