Combining desloratadine and pseudoephedrine in the treatment of seasonal allergic rhinitis

Abstract

Nonsedating antihistamines are a first-line therapy in the management of allergic rhinitis. They relieve the majority of the histamine-mediated symptoms of the condition, including rhinorrhea, sneezing, and pruritus. The nonsedating antihistamine desloratadine is effective in alleviating the symptoms of both seasonal and perennial allergic rhinitis. It may also have some decongestant properties, and thus help to alleviate nasal congestion. Administering desloratadine in combination with the decongestant pseudoephedrine may offer allergic rhinitis patients with moderate-to-severe nasal congestion the benefits of desloratadine’s effectiveness for alleviating histamine-mediated symptoms plus pseudoephedrine’s relief from nasal congestion. This drug profile reviews a combination therapy containing desloratadine and pseudoephedrine, approved in the USA for the relief of the symptoms of seasonal allergic rhinitis, including nasal congestion.
