Insomnia has also been found to be more severe in this population, with frequent complaints regarding problems with sleep maintenance and early morning awakening.5,6 Consequences of disturbed sleep in older people include impairments in memory, concentration, daytime performance at work or while driving and increased risk of falls.7,8, While nonpharmacological approaches are important for managing insomnia, pharmacotherapy is often necessary in treating patients with insomnia.7,9 Benzodiazepine receptor agonists and benzodiazepines are typically considered first-line agents for the management of insomnia.7,8 These drugs are associated with important adverse effects in older people, such as falls and fractures, cognitive impairment, withdrawal symptoms, rebound insomnia, carryover sedation and increased risk of drug dependence and abuse.10 Other commonly used drugs in this population include trazodone, mirtazapine and melatonin, and while the latter is thought to be safe, evidence of efficacy for these agents is inconsistent and additional pharmacotherapeutic options are welcome and necessary.7,8, Histamine is one of the key neurotransmitters of wakefulness, so it is not surprising that doxepin, a drug with selective histamine H1 receptor blockade, has been recently introduced as a new agent for insomnia in Canada.11 Historically, doxepin has been used to treat depression and anxiety disorders, with its sedative effects improving disrupted sleep.12 At antidepressant doses (25-300 mg per day), however, doxepin possesses significant anticholinergic and antinoradrenergic properties, leading to dose-limiting side effects.12 This may be explained by its pharmacology, because at doses exceeding 25 mg, doxepins selectivity for H1 receptors is lost and additional receptors (e.g., muscarinic, noradrenergic) are affected.13 In contrast, ultralow doses of doxepin (3 mg and 6 mg per day) appear to exhibit potent and highly selective H1 receptor antagonism and are nearly free from antimuscarinic effects.5,6,10,12,13,14 Marketed as Silenor, ultra-low-dose doxepin has been available in the United States to treat insomnia since 2010 and is currently available in Canada for insomnia characterized by frequent nocturnal awakening and/or early morning awakenings.15,16.
