Background:

Cetirizine Impurity B dihydrochloride is an impurity of Cetirizine dihydrochloride. Cetirizine, a second-generation antihistamine, is a specific, orally active and long-acting histamine H1-receptor antagonist. Cetirizine marks antiallergic properties and inhibits eosinophil chemotaxis during the allergic response[1][2][3].
