Brief Summary

Suvorexant (trade name Belsomra) is an orexin receptor antagonist that has TGA approval for the treatment of insomnia, characterised by difficulties with sleep onset and/or sleep maintenance. It may also have a role in addictions as the orexins play a critical role in drug addiction and reward-related behaviours. Orexins appear to be involved in both alcohol withdrawal and in alcohol seeking triggered by external cues (eg contexts or stressors) through both OX1 and OX2 receptor signalling. Chief investigator, Professor Lawrence was the first to demonstrate a role for endogenous orexin signaling in alcohol-seeking. Alcohol is known to effect the sleep of healthy and alcohol dependent individuals with effects on daytime sleepiness, physiological functions during sleep, and the development of sleep disorders. There are various estimates of the co-occurrence of insomnia and alcohol use disorder ranging from 36-72%. In alcohol dependent individuals sleep is disturbed both while drinking and for months of abstinence and abstinent sleep disturbance is predictive of relapse. This proposal aims to evaluate the use of suvorexant as a safe and effective pharmacotherapy to treat sleep disorders in alcohol dependent patients undergoing acute alcohol withdrawal and thereafter for six months. The study will also examine the effectiveness of suvorexant in reducing craving for alcohol and promoting duration of abstinence. This will be the first double blind controlled trial of suvorexant in the management of the alcohol withdrawal syndrome and maintenance of abstinence post withdrawal.

Outcome Measures

Primary Outcomes (1)

  • Sleep measure

    Change in polysomnography sleep efficiency measure from baseline and at end of inpatient stay. Portable Polysomnography is multichannel recording of the electrophysiological markers of sleep. Polysomnography (PSG) records brain activity, eye movements and muscle tone to identify stages of sleep. Sleep efficiency measure is number of minutes of sleep divided by the number of minutes in bed {%}).

    7-10 days

Secondary Outcomes (8)

  • Sleep measure

    25 weeks

  • Sleep quality: Pittsburgh Sleep Quality Index (PSQI)

    25 weeks

  • Sleepiness measure

    25 weeks

  • Abstinence measure

    25 weeks

  • Relapse measure
