| The active ingredient of Higuard azelastine hydrochloride exhibits anti-allergic effects by inhibiting and releasing leukotriens and histamine that cause allergy, relieving allergic symptoms including rhinitis (sneezing, runny and stuffy nose) and skin problems (urticaria, eczema, etc). Azelastine hydrochloride is a relatively selective histamine H1 antagonist/mast cell stabilizer and an inhibitor of the release of histamine and other mediators from cells involved in the allergic response. |
