is desloratadine and loratadine the same thing?
Loratadine is probably best known as Claritin although it does go by other brand names, such as Loradamed, Alavert, and even simply Allergy Relief. Desloratadine is best known as Clarinex. Both of these medications are histamine H1 receptor antagonists, with desloratadine being a metabolite of loratadine.
