Current Primary Outcome Measures ^ICMJE (submitted: February 12, 2013)	Mean Major Symptom Complex (MSC) Score by Post-Treatment Evaluation Time Point (From 180 Minutes to 300 Minutes) [ Time Frame: From time of sensitization (time 0) to end of visit (~8 hours) ] [ Designated as safety issue: No ] The MSC Score is calculated as the sum of 5 individual symptom scores for Runny Nose, Itchy Nose, Sneezing, Watery Eyes, and Itchy Eyes. Each individual symptom is rated on a 5-point scale of severity: 0 = None (No symptoms), 1 = MILD (Symptom is present, but easily tolerated), 2 = MODERATE (Awareness of symptoms, bothersome, but tolerable), 3 = SEVERE (Definite awareness of symptoms, difficult to tolerate but does not interfere with activities), 4 = VERY SEVERE (Difficult to tolerate and interferes with the activities of daily living). The total MSC score ranges from 0 - 25. Increasing scores are associated with increasing severity.

Descriptive Information
Brief Title ^ICMJE	A Study of Onset of Action of Loratadine and Fexofenadine in Participants With Seasonal Allergic Rhinitis (P08712)
Official Title ^ICMJE	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
Brief Summary	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.
