In brief: Similar
Desloratidine is the active metabolite of loratidine.
Loratidine is available as Claritin (loratadine) and must be metabolized to desloratidine in the liver to become the active metabolite desloratidine. However, desloratidine is available as Clarinex and is already in the more potent form.
