The Effects of Nabilone on Sleep in Fibromyalgia: Results of a Randomized Controlled Trial
BACKGROUND : Sleep disorders affect many patients with chronic pain conditions . Cannabis has been reported by several patient population s to help sleep . We evaluated the safety and efficacy of nabilone , a synthetic cannabinoid , on sleep disturbance in fibromyalgia ( FM ) , a disease characterized by widespread chronic pain and insomnia . METHODS : We conducted a r and omized , double-blind , active-control , equivalency crossover trial to compare nabilone ( 0.5–1.0 mg before bedtime ) to amitriptyline ( 10–20 mg before bedtime ) in patients with FM with chronic insomnia . Subjects received each drug for 2 wk with a 2-wk washout period . The primary outcome was sleep quality , measured by the Insomnia Severity Index and the Leeds Sleep Evaluation Question naire . Secondary outcomes included pain , mood , quality of life , and adverse events ( AEs ) . RESULTS : Thirty-one subjects were enrolled and 29 completed the trial ( 26 women , mean age 49.5 yr ) . Although sleep was improved by both amitriptyline and nabilone , nabilone was superior to amitriptyline ( Insomnia Severity Index difference = 3.2 ; 95 % confidence interval = 1.2–5.3 ) . Nabilone was marginally better on the restfulness ( Leeds Sleep Evaluation Question naire difference = 0.5 [ 0.0–1.0 ] ) but not on wakefulness ( difference = 0.3 [ −0.2 to 0.8 ] ) . No effects on pain , mood , or quality of life were observed . AEs were mostly mild to moderate and were more frequent with nabilone . The most common AEs for nabilone were dizziness , nausea , and dry mouth . CONCLUSIONS : Nabilone is effective in improving sleep in patients with FM and is well tolerated . Low-dose nabilone given once daily at bedtime may be considered as an alternative to amitriptyline . Longer trials are needed to determine the duration of effect and to characterize long-term safety
