Nabilone

Résumé
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.
