Clinical terms

Desloratadine falls under the category of non-sedating antihistamines, classified with ATC Code R06AX27. Approved by Health Canada, it serves as a selective peripheral H1-receptor antagonist. This means it focuses its action on peripheral H1 receptors to reduce allergic reactions without significantly affecting the central nervous system.

Indications include allergic rhinitis (both seasonal and perennial) and chronic idiopathic urticaria. The medication effectively addresses symptoms such as rhinorrhea, nasal and ocular pruritus, sneezing, and congestion.
