How does the drug work?
Histamine is responsible for the appearance and development of allergic reactions. During the reception of this drug cetirizine (the main active substance of Cetrin), getting into the body, binds to the receptors and simply blocks them. In this case, histamine, which is excreted, simply can not contact its receptors and affect the body. Thanks to Tsetrin, the blocking of the allergic reaction occurs at the cellular level. In addition, it reduces the activity of eosinophils and cytokines, which affect the maintenance of the inflammatory reaction.
