Description

Application

Cetirizine dihydrochloride has been used as an antagonist for histamine receptors H1 in HSDSEAP (poly) clonal cells derived from human embryonic kidney HEK-293 cells. It has also been used as a ligand in the crystallization of equine serum albumin cetirizine complex.

Biochem/physiol Actions

Cetirizine is a racemic mixture of (R)-levocetirizine and (S)-dextrocetirizine. It exists as a zwitterion at acidic pH and gets absorbed by passive diffusion. Cetirizine is a prescribed drug for allergic rhinitis and chronic idiopathic urticaria.

Cetirizine hydrochloride is a non-sedating type histamine H1-receptor antagonist.

Cetirizine hydrochloride is an orally active and selective H1-receptor antagonist. Antihistaminic; Piperazines. Non-sedating type histamine H1-receptor antagonist; major metabolite of hydroxyzine. Pharmacological activity resides primarily in the (R)-isomer.
