Beschreibung

Application

Terfenadine has been used to study the role of histamine in itch related to proteinase-activated receptors (PARs) in mice. Terfenadine has also been used to block histamine receptor type 1 to study the pathogenesis of 2,4-dinitrobenzene sulfonic acid (DNBS)-induced ulcerative colitis in rats.

Terfenadine has been used as a positive control in electrophysiology recordings. It has also been used as a constituent of internal standard solution in liquid chromatography-mass spectrometry (LC-MS).

Biochem/physiol Actions

Nicht sedierender H1 Histamin-Rezeptor-Antagonist der zweiten Generation.

Non-sedating second generation H1 histamine receptor antagonist. Mainly metabolized by Cyp3A4, 5, 7. Inhibits CYP2C8.

Terfenadine acts a potential anti-histamine and is used in the treatment of allergic rhinitis and chronic urticaria.
