What is Cetirizine?
Cetirizine is an anti-allergic drug. Cetirizine, marketed under the Zyrtec brand, is classified as an antihistamine. The medication is available in various formulations, such as tablets and oral solutions. Other drugs that are included in the cetirizine class are desloratadine, fexofenadine, and levocetirizine.
Uses of Cetirizine
Cetirizine is used to treat symptoms of seasonal allergies, rash or itching.
How does it work?
Cetirizine exerts its pharmacological effects through the process of binding to and subsequently inhibiting the H1 receptors, which play a pivotal role in mediating allergic reactions. The medication exhibits selective action on peripheral histamine-1 (H-1) receptors, which are histamine receptors situated in regions outside of the central nervous system, such as the brain and spinal cord. This action effectively inhibits the physiological effects of histamine. This intervention aids in alleviating symptoms such as sneezing, pruritus, and rhinorrhea.
