Cetirizine is a second-generation selective H1-histamine receptor antagonist with antiallergic effects that inhibits eosinophil chemotaxis during allergic reactions. Cetirizine has minimal central nervous system depressant effects.

Cetirizine-D8 dihydrochloride is a deuterium-labeled Cetirizine dihydrochloride (TMSM-0681). Cetirizine is a second-generation antihistamine and a long-acting histamine H1-receptor antagonist.

Levocetirizine Dihydrochloride (Xyzal Dihydrochloride) is a third-generation peripheral H1-receptor antagonist. Acting as an antihistaminic agent, it specifically targets the histamine H1-receptor. Levocetirizine Dihydrochloride is the R-enantiomer of Cetirizine, which gives it a higher affinity for the H1-receptor than the S-enantiomer. Due to this enhanced affinity, Levocetirizine Dihydrochloride is effective in treating allergic rhinitis and chronic idiopathic urticaria.

Cetirizine-D4 is a deuterium-labeled Cetirizine. Cetirizine (T0089L) is a second-generation antihistamine and a long-acting histamine H1-receptor antagonist.

Cetirizine-D8 is a deuterium-labeled Cetirizine. Cetirizine (T0089L) is a second-generation antihistamine and a long-acting histamine H1-receptor antagonist.

Cetirizine dihydrochloride (UCB P071) is an effective second-generation histamine H1 antagonist that is potent in the therapy of allergic rhinitis, confirmed urticaria, and pollen-induced asthma. Unlike other conventional antihistamines, it does not cause side effects of drowsiness or anticholinergic.

Cetirizine Dihydrochloride (Standard) is the standard substance of Cetirizine Dihydrochloride, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Cetirizine dihydrochloride (UCB P071) is an effective second-generation histamine H1 antagonist that is potent in the therapy of allergic rhinitis, confirmed urticaria, and pollen-induced asthma. Unlike other conventional antihistamines, it does not cause side effects of drowsiness or anticholinergic.

(S)-Cetirizine dihydrochloride ((S)-P071) is an orally active histamine H1 receptor antagonist with a Ki value of 39.1 nM. By binding to the histamine H1 receptor, it blocks the action of histamine, providing antiallergic effects. (S)-Cetirizine dihydrochloride shows potential for research in allergic conditions such as allergic rhinitis.
