Bilastine is a selective histamine H
1 receptor antagonist. On the other hand, the results of studies on bilastine confirmed the lack of significant antagonism against not only histamine H
2 and H
3 receptors but also serotonin, bradykinin, leukotriene D
4, calcium, muscarinic M
3-receptors, α
1-adrenoceptors, and β
2-adrenoceptors. Furthermore, bilastine do not cause sedation or interact with cytochrome P 450. Therefore, bilastine is used as a second generation H
1-antihistamine for the treatment of allergic rhinitis and chronic urticarial. For your reference, [
P2382] is a synthetic intermediate of bilastine.(The product is for research purpose only.)
