second generation antihistamine

Cetirizine Impurity B dihydrochloride (De(carboxymethoxy) Cetirizine Acetic Acid Dihydrochloride) is an impurity of Cetirizine dihydrochloride. Cetirizine is a second-generation antihistamine. Cetirizine is a specific, orally active and long-acting histamine H1-receptor antagonist. Cetirizine marks antiallergic properties and inhibits eosinophil chemotaxis during the allergic response.

Cetirizine D4 dihydrochloride is a deuterium-labeled Cetirizine. Cetirizine is a second-generation antihistamine and a long-acting histamine H1-receptor antagonist.

Cetirizine Impurity D is an impurity of Cetirizine. Cetirizine is a second-generation antihistamine that acts as a specific, orally active, and long-acting antagonist of the histamine H1-receptor. Cetirizine exhibits antiallergic properties and inhibits eosinophil chemotaxis in response to allergies.

Cetirizine Impurity C is an impurity of Cetirizine. Cetirizine is a second-generation antihistamine and the carboxylated metabolite of hydroxyzine. It acts as a specific, orally active, and long-acting antagonist of the histamine H1-receptor[1][2].

Mizolastine (SL 850324) (IC50= 47 nM) is a histamine H1-receptor antagonist.It is used in the treatment of allergic reactions such as hay fever (seasonal allergic rhinitis), hives.

Fexofenadine hydrochloride (Terfenidine carboxylate hydrochloride) is a second generation antihistamine that is used for the treatment of allergic rhinitis, angioedema and chronic urticaria.

Cetirizine D8 is a deuterium-labeled Cetirizine. Cetirizine is a second-generation antihistamine and a long-acting histamine H1-receptor antagonist.

Cetirizine methyl ester, an impurity of Cetirizine, serves as a specific, orally active, and long-acting histamine H1-receptor antagonist. As a second-generation antihistamine and the carboxylated metabolite of hydroxyzine, Cetirizine effectively counters allergic reactions [1].

Deschloro Cetirizine Dihydrochloride is an impurity of Cetirizine, a second-generation antihistamine and the carboxylated metabolite of hydroxyzine. It functions as a specific, orally active, and long-acting histamine H1-receptor antagonist.

Cetirizine D4 is a deuterium-labeled Cetirizine. Cetirizine is a second-generation antihistamine and a long-acting histamine H1-receptor antagonist.

Cetirizine Impurity C dihydrochloride, a specific impurity of Cetirizine, is associated with a second-generation antihistamine that serves as the carboxylated metabolite of hydroxyzine. This compound acts as a specific, orally active, and long-acting antagonist of the histamine H1-receptor [1] [2].

Cetirizine D8 dihydrochloride is a deuterium-labeled Cetirizine. Cetirizine is a second-generation antihistamine and a long-acting histamine H1-receptor antagonist.
