DescriptionDaridorexant, formerly known as nemorexant, is a selective dual orexin receptor antagonist used to treat insomnia. Insomnia is characterized by difficulties with sleep onset and/or sleep maintenance and impairment of daytime functioning. It chronically affects the person's daily functioning and long-term health effects, as insomnia is often associated with comorbidities such as hypertension, diabetes, and depression. Conventional treatments for insomnia include drugs targeting gamma-aminobutyric acid type-A (GABA-A), serotonin, histamine, or melatonin receptors; however, undesirable side effects are frequently reported, such as next-morning residual sleepiness, motor incoordination, falls, memory and cognitive impairment. Novel drugs that target orexin receptors gained increasing attention after discovering the role of orexin signalling pathway in wakefulness and [almorexant], an orexin receptor antagonist that improved sleep. Daridorexant was designed via an intensive drug discovery program to improve the potency and maximize the duration of action while minimizing next-morning residual activity.[A244225] Daridorexant works on orexin receptors OX1R and OX2R to block the binding of orexins, which are wake-promoting neuropeptides and endogenous ligands to these receptors. Daridorexant reduces overactive wakefulness: in the investigational trials, daridorexant reportedly improved sleep and daytime functioning in patients with insomnia.[A244225] It was approved by the FDA on January 10, 2022, under the name QUVIVIQ.[L39660] as the second orexin receptor antagonist approved to treat insomnia following [suvorexant].[A244280] Daridorexant was approved by the European Commission on May 3, 2022, as the first dual orexin receptor antagonist approved in the market,[L41725] and by Health Canada on April 26, 2023.[L46307]

IndicationIn the US and Europe, daridorexant is indicated for the treatment of adult patients with insomnia characterized by difficulties with sleep onset and/or sleep maintenance.[L39655, L46307] The European prescribing information states that insomnia should be characterized by symptoms that are present for at least three months and have a considerable impact on daytime functioning.[L41720]
