Hydroxyzine Pamoate (Bobsule) is a histamine H1 receptor antagonist that is effective in the treatment of chronic urticaria, dermatitis, and histamine-mediated pruritus. Unlike its major metabolite CETIRIZINE, it does cause drowsiness. It is also effective as an antiemetic, for relief of anxiety and tension, and as a sedative.

Hydroxyzine (Hydroxyzine free base) is an antagonist of histamine H1-receptor.

Hydroxyzine dihydrochloride-d4 is a deuterated compound of Hydroxyzine dihydrochloride. Hydroxyzine dihydrochloride has a CAS number of 2192-20-3. Hydroxyzine hydrochloride is a histamine H1 receptor antagonist that is effective in the treatment of chronic urticaria, dermatitis, and histamine-mediated pruritus. Unlike its major metabolite CETIRIZINE, it does cause drowsiness. It is also effective as an antiemetic, for relief of anxiety and tension, and as a sedative.

Hydroxyzine-d8 DiHCl is a deuterated compound of Hydroxyzine DiHCl. Hydroxyzine DiHCl has a CAS number of 2192-20-3.

Hydroxyzine dihydrochloride (Hydroxyzine 2HCl) is a histamine H1 receptor antagonist that is effective in the treatment of chronic urticaria, dermatitis, and histamine-mediated pruritus. Unlike its major metabolite CETIRIZINE, it does cause drowsiness. It is also effective as an antiemetic, for relief of anxiety and tension, and as a sedative.

Hydroxyzine dihydrochloride-d10 is a deuterated compound of Hydroxyzine dihydrochloride.

Hydroxyzine dihydrochloride-d8 is a deuterated compound of Hydroxyzine dihydrochloride.

Hydroxyzine D8, a deuterium-labeled version of Hydroxyzine, acts as a histamine H1-receptor antagonist.

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].

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 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].
