Orexin (/ ɒ ˈ r ɛ k s ɪ n /), also known as hypocretin, is a neuropeptide that regulates arousal, wakefulness, and appetite. [5] It exists in the forms of orexin-A and orexin-B.The most common form of narcolepsy, type 1, in which the individual experiences brief losses of muscle tone ("drop attacks" or cataplexy), is caused by a lack of orexin in the brain due to destruction of the cells ...
An orexin receptor antagonist, or orexin antagonist, is a drug that inhibits the effect of orexin by acting as a receptor antagonist of one (selective orexin receptor antagonist or SORA) or both (dual orexin receptor antagonis or DORA) of the orexin receptors, OX 1 and OX 2. [ 1] Medical applications include treatment of sleep disorders such as ...
Suvorexant, sold under the brand name Belsomra, is an orexin antagonist medication which is used in the treatment of insomnia. [2] [6] It is indicated specifically for the treatment of insomnia characterized by difficulties with sleep onset and/or maintenance in adults. [2] [6] Suvorexant helps with falling asleep faster, sleeping longer, being ...
Orexin, otherwise known as hypocretin, is a neuropeptide that acts within the brain to regulate appetite and wakefulness as well as a number of other cognitive and physiological processes. [ 27 ] [ 38 ] [ 39 ] Loss of these orexin-producing neurons causes narcolepsy and most individuals with narcolepsy have a reduced number of these neurons in ...
Orexins strongly excite various brain nuclei to affect an organism's wakefulness by affecting their dopamine, norepinephrine, histamine and acetylcholine systems. [3] These systems work together to stabilize the organism's sleep cycles. Once made, the orexin peptides can bind to the orexin receptor; which is a G protein-coupled receptor. This ...
Danavorexton (developmental code name TAK-925) is a selective orexin 2 receptor agonist. [1] It is a small-molecule compound and is administered intravenously. [1] [2] The compound was found to dose-dependently produce wakefulness to a similar degree as modafinil in a phase 1 clinical trial. [1] [3] As of March 2021, danavorexton is under ...
Daridorexant. Daridorexant, sold under the brand name Quviviq, is an orexin antagonist medication which is used for the treatment of insomnia. [1] [4] [6] [7] [8] Daridorexant is taken by mouth. [1] [4] [7] Side effects of daridorexant include headache, somnolence, and fatigue. [1] [7] The medication is a dual orexin receptor antagonist (DORA).
Nevertheless, after giving this treatment to a patient with undetectable orexin levels in the cerebrospinal fluid after only 15 days after the disease onset, the cataplexy was improved and the orexin levels started to normalise. [17] Plasmapheresis: should be similar with IVIgs but it is more invasive and for it even less data is available. [16]
