Desloratadine-d₄ hydrobromide  (Synonyms: 地氯雷他定氢溴酸-d₄; Sch34117-d₄ hydrobromide)

Desloratadine-d₄ hydrobromide is deuterated labeled Desloratadine (HY-B0539). Desloratadine (Sch34117) is the orally active major metabolite of the nonsedating H1-antihistamine Loratadine. Desloratadine is a selective H1-receptor antagonist that has anti-allergic and anti-inflammatory activities^[1][2].

氢、碳和其他元素的稳定重同位素已被纳入药物分子中，主要作为药物开发过程中定量的示踪剂。氘化引起了人们的关注，因为它可能影响药物的药代动力学和代谢谱^[1]。
