The Effect of Oral Guaifenesin on Pediatric Chronic Rhinitis: A Pilot Study

Brief Summary:
This is a 14-day, randomized, placebo-controlled, parallel group, masked clinical trial of oral guaifenesin for the therapy of Chronic Rhinitis (CRS) in 36 children between the ages of 7 and 18 years. The study investigates the effectiveness of guaifenesin in the relief of nasal symptoms in children with CRS using the sinonasal 5 survey (SN-5) in comparison to nasal airway volume, and biophysical properties of nasal secretion. The investigators hypothesize that Guaifenesin use over a period of 14 days improves subjective nasal complaints in pediatric patients with chronic rhinitis and nasal congestion, as measured by the SN-5 survey compared to use of placebo. There will be an observed improvement in nasal volume and cross-sectional area following use of guaifenesin, and nasal secretions will have more favorable mucociliary and sneeze clearability compared to use of placebo.

Arm Intervention/treatment
Placebo Comparator: Placebo
Placebo is provided by the sponsor and is identical in composition to the treatment only lacking active drug.
Drug: Placebo
Children aged 7-11 years old will receive placebo 200 mg three times a day (TID), while children older than 12 will receive Placebo 400 mg TID.

Active Comparator: Guaifenesin Drug: Guaifenesin
Children aged 7-11 years old will receive guaifenesin 200 mg TID, while children older than 12 will receive guaifenesin 400 mg TID.

Primary Outcome Measures :
  1. Change in Subjective Nasal Scoring [ Time Frame: Baseline to 10 Minutes ]
    The Sinus and Nasal Quality of Life Survey (SN-5) questionnaire assesses the impact of infection on nasal symptoms, emotion, and activity. The SN-5 is a 5-item scale with each item rated on a scale of worsening symptoms from 1 (none of the time) through 7 (all of the time). Items were averaged to yield a single score ranging from 1 (better outcomes) to 7 (worse outcomes). Scores were used to asses change in disease severity and the impact of interventions on subjective complaints from baseline to follow-up.

Secondary Outcome Measures :
  1. Nasal Volume [ Time Frame: 15 Minutes ]
    Acoustic rhinometry is used to measure cross-sectional volume of the nasal cavity allowing the calculation of nasal volume.

  2. Nasal Secretion Collection [ Time Frame: 10 minutes ]
    To measure the biophysical properties of nasal secretions for improved mucus clearance.
