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 ...
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 ...
The orexin receptor (also referred to as the hypocretin receptor) is a G-protein-coupled receptor that binds the neuropeptide orexin. There are two variants, OX 1 and OX 2 , each encoded by a different gene ( HCRTR1 , HCRTR2 ).

Vornorexant, also known by its developmental code names ORN-0829 and TS-142, is an orexin antagonist medication which is under development for the treatment of insomnia and sleep apnea. [3] [4] [5] It is a dual orexin OX 1 and OX 2 receptor antagonist (DORA). [5] [6] The medication is taken by mouth. [1]
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 ...
The Kaiser Family Foundation studied how consumer-driven health plans cover pregnancy. They found wide variations in cost sharing. Pregnant women could face exposure to high out-of-pocket costs under consumer-driven health plans, particularly when complications arise.
