Rhinitis Clinical Trial
Official title:
A Double-Blind, Parallel, Randomized, Placebo Controlled Trial to Evaluate Onset of Action of Loratadine and Fexofenadine in Subjects With Seasonal Allergic Rhinitis in a Pollen Challenge Chamber
The purpose of this study is to determine the onset of action of two commercially available
over-the-counter antihistamines (Loratadine and
Fexofenadine) in a model of seasonal allergic rhinitis (SAR). Participants undergo
sensitization exposures to Mountain Cedar (juniperus ashei) pollen in a Biogenics Research
Chamber; those who demonstrate an adequate allergic response determined by the Major Symptom
Complex (MSC) score will then receive drug.
