What is Desloratadine?

Desloratadine belongs to the group of the most effective antiallergic drugs and is a blocker of H1 histamine receptors. The drug has a long-lasting effect and is the primary active metabolite of the substance loratadine. Desloratadine inhibits the release of histamine and C4 leukotriene from basophils, which prevents the development of allergic reactions in the body manifested by rash, itching, sneezing, runny nose or lacrimation.
