Hydroxyzine, sold under the brand names Atarax and Vistaril among others, is an antihistamine medication. [8] It is used in the treatment of itchiness, anxiety, insomnia, and nausea (including that due to motion sickness). [8] It is used either by mouth or injection into a muscle. [8] Hydroxyzine works by blocking the effects of histamine. [9]
An H 3 receptor antagonist is a type of antihistaminic drug used to block the action of histamine at H 3 receptors.. Unlike the H 1 and H 2 receptors which have primarily peripheral actions, but cause sedation if they are blocked in the brain, H 3 receptors are primarily found in the brain and are inhibitory autoreceptors located on histaminergic nerve terminals, which modulate the release of ...
Hydroxyzine doesn't act on u-opioid receptors, and the vast majority of anecdotal subjective information (pretty much the only avaliable information on how recreational drugs feel) indicates that hydroxyzine is not "fun" and does not feel like an opiate or even a GABA agonist (benzodiazepine, barbituate, ethanol, meprobamate, carisoprodol, etc ...
H 1-antihistamines work by binding to histamine H 1 receptors in mast cells, smooth muscle, and endothelium in the body as well as in the tuberomammillary nucleus in the brain. Antihistamines that target the histamine H 1-receptor are used to treat allergic reactions in the nose (e.g., itching, runny nose, and sneezing).
“There’s so many other products out there that really do work,” Dr. James Tracy, vice president of the American College of Allergy, Asthma and Immunology, previously told Yahoo Life.
In Texas, Florida, and more than a dozen other states, users who try to access the world’s largest pornography website are greeted by a surprising sight: a message on a black screen telling them ...
These compounds are structurally related to the ethylenediamines and the ethanolamines, and produce significant anticholinergic adverse effects with the exception of hydroxyzine, which has low to no affinity for muscarinic acetylcholine receptors and therefore produces negligible anticholinergic side-effects. [16]
“To ensure that no one remains stressed at work, we have made the difficult decision to part ways with employees who indicated significant stress.” The termination, according to Jha, was ...
