Nabilone, sold under the brand name Cesamet among others, is a synthetic cannabinoid with therapeutic use as an antiemetic and as an adjunct analgesic for neuropathic pain. It mimics tetrahydrocannabinol (THC), the primary psychoactive compound found naturally occurring in Cannabis.
The Food and Drug Administration in the United States has indicated nabilone for chemotherapy-induced nausea/vomiting. In other countries, such as Canada, it is widely used as an adjunct therapy for chronic pain management. Numerous trials and case studies have demonstrated modest effectiveness for relieving fibromyalgia and multiple sclerosis.
Nabilone is used to treat nausea and vomiting in people under chemotherapy.
Nabilone has shown modest effectiveness in relieving fibromyalgia. A 2011 systematic review of cannabinoids for chronic pain determined there was evidence of safety and modest efficacy for some conditions.
The main settings that have seen published clinical trials of nabilone include movement disorders such as parkinsonism, chronic pain, dystonia and spasticity neurological disorders, multiple sclerosis, and the nausea of cancer chemotherapy. Nabilone is also effective in the treatment of inflammatory bowel disease, especially ulcerative colitis.
In one study of current daily users of cannabis, oral nabilone at 4, 6, and 8 mg produced sustained and dose-dependent mood elevation and psychomotor slowing comparable to 10 or 20 mg oral dronabinol (THC). Nabilone had a slower onset of peak action and a greater dose-dependence of effects, which the investigators attributed to greater bioavailability.
A study comparing nabilone with metoclopramide, conducted before the development of modern 5-HT3 antagonist anti-emetics such as ondansetron, revealed that patients taking cisplatin chemotherapy preferred metoclopramide, while patients taking carboplatin preferred nabilone to control nausea and vomiting.
Nabilone is sometimes used for nightmares in post-traumatic stress disorder, but there have not been studies longer than nine weeks, so effects of longer-term use are not known.

Synthetic cannabinoids are a class of designer drug molecules that bind to the same receptors to which cannabinoids (THC, CBD and many others) in cannabis plants attach. These novel psychoactive substances should not be confused with synthetic phytocannabinoids (THC or CBD obtained by chemical synthesis) or synthetic endocannabinoids from which they are in many aspects distinct. Typically, synthetic cannabinoids are sprayed onto plant matter and are usually smoked, although they have also been ingested as a concentrated liquid form in the US (United States) and UK (United Kingdom) since 2016.

Le cannabis médical (appelé aussi cannabis thérapeutique, marijuana médicale ou marijuana thérapeutique) désigne le Cannabis sativa (désignation botanique du chanvre), et, par extension, l'ensemble des dizaines de phyto-cannabinoïdes destinés à un usage purement médical, généralement prescrits pour leurs vertus antiémétiques.
Les cannabinoïdes sont un groupe de substances chimiques qui activent les présents dans le corps humain et chez les mammifères. Le premier cannabinoïde isolé fut le tétrahydrocannabinol, puis le cannabidiol et les autres cannabinoïdes. Ces découvertes ont été initiées et effectuées dans les années 1960 par le Pr. Raphael Mechoulam, chercheur israélien. Il existe environ 100 différents cannabinoïdes présents dans la plante de cannabis et des chercheurs dans le monde entier étudient actuellement leurs potentiels effets thérapeutiques et leurs mécanismes de fonctionnement dans le corps humain.
