Description

Ebastine-d5 is intended for use as an internal standard for the quantification of ebastine by GC- or LC-MS. Ebastine is a potent second generation histamine H1 receptor antagonist (IC50 = 45 nM) that does not cross the blood brain barrier.1 It undergoes extensive first-pass metabolism by hepatic cytochrome P450 3A4 into its active carboxylic acid metabolite, carebastine , which exerts most of the pharmacological effects.2 At 10 μM, ebastine has been shown to inhibit T cell proliferation and the production of Th2-type pro-inflammatory cytokines by macrophages.3
