Fexofenadine-d10 is intended for use as an internal standard for the quantification of fexofenadine by GC- or LC-MS. Fexofenadine is a histamine H1 receptor antagonist (Ki = 10 nM).1 It reverses contraction of isolated rat tracheal strips induced by acetyl-β-methylcholine .2 Fexofenadine inhibits expression of IL-8 in TNF-α-stimulated HCT116 and COLO 205 cells.3 Oral administration of fexofenadine (2 and 10 mg/kg) reduces severity of colitis and phospho-IκB kinase activation in a mouse model of colitis induced by dextran sulfate sodium .
