CBTi and traditional pharmacological treatments

CBTi

CBTi is an evidence-based alternative to drug therapy and is the recommended first‑line treatment for chronic insomnia, given face‑to‑face or digitally.1,7,8 Treatment involves behavioural techniques including sleep restriction, stimulus control, cognitive therapy and relaxation training.1,7,8 Some patients may report mild daytime sedation in the early stages of sleep restriction and stimulus control.1 The effects of CBTi may last after treatment has ended and there is evidence to suggest benefit to mood, wellbeing, and social and occupational functioning.1

If CBTi is not effective or not available, or if the patient is unsuitable or non‑compliant, drug treatment can be considered.8

Traditional pharmacological treatments

Benzodiazepines (BZ)/ benzodiazepine receptor agonists (BZRAs)

BZs and BZRAs are effective for the treatment of short-term insomnia (<4 weeks).8 BZs are gamma‑aminobutyric acid (GABA) receptor agonists which enhance GABA‑mediated inhibition of the CNS arousal systems, promoting sleep.1 These include nitrazepam, lormetazepam and temazepam.8 These drugs are only recommended for short‑term treatment as patients can develop tolerance, which gradually reduces their effectiveness, and drug dependence can also occur.1,7,8 BZs are also associated with so‑called ‘hangover effects’ such as daytime drowsiness due to their long half‑lives.1 BZs/BZRAs with shorter half‑lives maybe associated with fewer of these effects.8

Note that NICE does not recommend the use of any BZ for the treatment of acute or chronic insomnia.3,4

Z-drugs

Z-drugs, also GABA receptor agonists, were developed to mitigate the negative effects of benzodiazepines used in the treatment of chronic insomnia.1 Their shorter half-lives versus benzodiazepines can make these drugs less effective at maintaining sleep during the night.1 Zolpidem and zopiclone are only recommended for short-term treatment as potential remains for tolerance and dependence.1,7

NICE does not recommend long-term management of chronic insomnia with hypnotic drugs. Treatment should be a short course (3-7 days) for severe symptoms or an acute exacerbation.1,7

Sedating antidepressants

Although tricyclic antidepressants have long been used for insomnia, this off-label use has little evidence of efficacy.1,8 Trazodone has been used for insomnia however there are few robust studies supporting its use.1 Mirtazepine has been shown to reduce insomnia in depression, particularly at the start of treatment.1 These drugs may be useful for the treatment of patients with concomitant chronic insomnia and depression/ mood disorders,1 but long-term treatment of chronic insomnia with antidepressants is not recommended due to side effects/ risks.8

Melatonin

Prolonged-release melatonin is indicated for people >55 years with primary insomnia.9 Initially it should be given for 3 weeks and, if the patient responds, treatment can be continued for 10 weeks.7 There should be an awareness of the risk of falls/ fractures when being prescribed in older adults.7 Some melatonin formulations are licensed for the treatment of insomnia associated with behavioural disorders in children and adolescents,10 although immediate-release melatonin is not recommended for insomnia, unless jet lag/ circadian factors are involved.1,8
