3.  Secondary:   Mean Change Postnasal Drip Reflective Score   [ Time Frame: 2 Weeks ]
  Hide Outcome Measure 3

Measure Type Secondary
Measure Title Mean Change Postnasal Drip Reflective Score
Measure Description Change from baseline after 2 weeks in responses to patient-completed diaries for reflective Total Nasal VMR Symptom Scores (rTVSS). TVSS is composed of 4 individual assessments, which included nasal congestion, rhinorrhea, post nasal drip and sneezing; each of the 4 assessments were rated using a 4 point scale that ranged in whole units from 0 (none) to 3 (severe). All 4 assessments are totaled for a composite score (TVSS score), the maximum of which could be 12. Reflective scores were assessed from the hour since the last dose of study medication.
Time Frame 2 Weeks  
Safety Issue No
