loratadine + placebo

Loratadine + placebo refers to a specific clinical trial intervention arm, primarily associated with studies conducted by Bayer to evaluate the efficacy and onset of action of antihistamines in seasonal allergic rhinitis. This regimen typically involves the oral administration of a 10 mg loratadine tablet alongside a placebo nasal spray, a design used to maintain double-blinding in trials comparing oral medications with intranasal therapies like azelastine. Loratadine is a second-generation, non-sedating H1-antihistamine that works as a selective peripheral histamine H1-receptor antagonist. It is indicated for the relief of symptoms such as sneezing, runny nose, and itchy eyes or throat. By blocking the action of histamine, a primary mediator of the allergic response, loratadine effectively manages the inflammatory symptoms of hay fever and other upper respiratory allergies.
