Ajulemic acid (IP-751) is a synthetic cannabinoid derivative of the non-psychoactive THC metabolite 11-carboxy-THC which shows useful analgesic and anti-inflammatory effects without causing a subjective "high".[1] It is being developed for the treatment of neuropathic pain and inflammatory conditions such as arthritis.[2] It does not however share the anti-emetic effects of other cannabinoids but may be useful for treating pain and chronic inflammatory conditions where nausea is not present.[3] Side effects include dry mouth, tiredness and dizziness. The mechanism of action has not yet been established, but ajulemic acid may activate the CB1 receptor in a different way to psychoactive cannabinoids. [4]
