Change From Baseline in Mean Average Score Using Pittsburgh Insomnia Rating Scale (PIRS) in Q1, Q3, Q17 and Q18 at Day 7

Time Frame: At Baseline and Day 7

The PIRS questionnaire had 3 sections (Section A \[Q1 to Q12\], Section B \[Q13 to 16\] and Section C \[Q17 to Q20\]). The following questions were asked from Section A : 1. One or more awakenings after getting to sleep and 3 Sleep that does not fully refresh you, and Section C: 17 Your sleep quality compared to most people and 18 Your satisfaction with your sleep. Section A question were scored as follows: 0= Not at all bothered, 1= slightly bothered, 2=moderately bothered, and 3= severely bothered. Section B, Q13 and 14 were scored as follows 0= Less than ½ hour, 1= between ½ to 1 hour, 2= between 1 to 3 hours and 3=more than 3 hours or I didn't sleep; Q15 and 16 were scored as 0=more than 7 hours, 1= between 4 to 7 hours, 2= between 2 to 4 hours, and 3=Less than 2 hours or I didn't sleep. Section C questions were scored as follows: 0=Excellent, 1=Good, 2=Fair, and 3=Poor. Lower PIRS score shows better sleep quality.

Change From Baseline in Mean Average Score of NRQLQ (Nocturnal Rhino Conjunctivitis Quality of Life Questionnaire) for Each Domain (Sleep, Sleep Time, Symptoms on Waking in the Morning, and Practical Problems) on the) at Day 7

Time Frame: At Baseline and Day 7

Participants scored all the domains of NRQLQ using same 7 points scale where 0=Not troubled and 6=extremely troubled. Sleep problems (difficulty getting sleep, unable to get a good night sleep or wake up during the night, restless \[tossing and turning\] and having to get up because stuffy nose or to blow nose using the score, scores range: Min-Max \[0-24\]), Sleep time problems (Nasal congestion or stuffy nose, sinus pressure or pain, runny nose, post-nasal drip \[drainage down back of nose/throat\], and headache, scores range: 0-30); Symptoms on waking in the morning (Feel tired and unrefreshed, nasal congestion or stuffy nose, congestion in sinuses, takes time to clear nighttime drainage after waking up, scores range:0-24); practical problems (have to avoid symptom triggers (such as dust, cigarette smoke, strong smells and perfumes, need to rub nose or eyes, and have to take medication, scores range: 0-18). Lower scores indicate improvement in the rhinitis symptoms.

Change From Baseline in Mean Sum of 7 Questions of Congestion Quantifier 7 Questionnaire (CQ7) at Day 7

Time Frame: At Baseline and Day 7

Participants answered following questions of CQ7 questionnaire: Q1 -How often did you have nasal stuffiness, blockage, or congestion?, Q2- How often did you have sinus pressure or pain in your face?, Q3-How often did you have to breathe through your mouth because you could not breathe through your nose?, Q4-How often did you have difficulty completely clearing your nose even after repeated blowing?, Q5-How often did any of these symptoms affect your ability to work, learn in school, or do the things you need to do?, Q6-How often did you awaken in the morning with nasal stuffiness, blockage, or congestion?, Q7-How often was your sleep affected by your nasal stuffiness, blockage, or congestion?. Their responses were scored using a 5 point scale where 0=none of the time; 1=a little of the time, 2=some of the time, 3=most of the time, 4=all of the time. Lower CQ7 scores reflect better nasal patency.
