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

This is a 14-day, randomized, placebo-controlled, parallel group, masked clinical trial of oral guaifenesin for the therapy of Chronic Rhinitis 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.

Further study details as provided by Virginia Commonwealth University:

Primary Outcome Measures:
  • Subjective nasal scoring [ Time Frame: 10 Minutes ]
    The Sinus and Nasal Quality of Life Survey (SN-5) questionnaire assess the impact of infection on nasal symptoms, emotion, and activity on a scale of worsening symptoms scored 1 through 7 to provide a quantifiable score capable of comparing both disease severity and the impact of interventions on subjective complaints.

Secondary Outcome Measures:
  • 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.

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