Fexofenadine hydrochloride (trade name: Allegra) belongs to a second-generation antihistamine pharmaceutical drug. It is mainly used for the treatment of allergy symptoms including watery eyes, hay fever, nasal congestion, urticaria, runny nose, itching eyes/nose, sneezing, hives, and itching. It is a kind of selectively peripheral H1 blocker. Its mechanism of action in vivo is through preventing the histamine-mediated activation of the H1 receptors, thus alleviating the symptoms related to allergy. Compared to the first-generation antihistamine drug, it is less prone to penetrate the blood-brain barrier, reducing the possibility to cause side effects such as drowsiness.
