Pyrilamine Maleate Info

What is ?

Pyrilamine Maleate, with the chemical name Mepyramine Maleate and CAS number 59-33-6, is a first-generation histamine H1 receptor antagonist. It is known for its ability to bind to a G protein-coupled form of the receptor, promoting an inactive state that interferes with Gq/11-mediated signaling. This compound is capable of permeating the blood-brain barrier, which can lead to drowsiness, and it also exhibits anticholinergic properties

Uses :

The primary use of Pyrilamine Maleate is in the treatment of allergic conditions, where it functions to alleviate symptoms such as itching, redness, and swelling by blocking the effects of histamine. It is a common ingredient in cold remedies and is used both parenterally and locally for conditions including skin eruptions. Additionally, Pyrilamine Maleate has been studied for its effects on various physiological processes, including its role in histaminergic systems and sleep, as well as its influence on cognitive functions like memory and learning . It is important to note that Pyrilamine Maleate is for research purposes only and should be handled and used according to appropriate scientific and legal standards
