Primary Outcome Measures:
  • Onset of action measured by change in total nasal symptom score Until "Onset of action" = until drug demonstrates and maintains a change greater than placebo compared to baseline [ Time Frame: Up to 6 hours ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change from baseline for individual symptoms of allergic seasonal rhinitis; overall assessment of efficacy [ Time Frame: Effect over 6 hours ] [ Designated as safety issue: No ]

Enrollment: 70
