Montelukast is a once daily LRA indicated for the treatment of allergic rhinitis and asthma, which is both safe and effective. Documented improvement in nasal congestion has been showed in patients with both seasonal and perennial allergic rhinitis. As demonstrated in recent publications, we fully anticipate that nasal congestion will be reduced in individuals afflicted with AR treated with montelukast. We have previously documented that a decrease in nasal congestion is associated with improved subjective sleep quality and subjective improvement in daytime somnolence. However, we have not demonstrated a cause and effect relationship. Currently, we have a study being performed that will allow us to assess the effect of nasal steroids on objective sleep by collecting data using a traditional overnight sleep test in subjects with congestion. We have not yet determined if subjective instruments for daytime somnolence correlate with objective measurements of improved daytime sleepiness. The purpose of this protocol will be three fold. First, we hope to determine the effectiveness of montelukast to reduce fatigue, somnolence and improve sleep, by reducing nasal congestion in allergic rhinitis. Two, we will assess the statistical relation between subjective instruments for sleepiness. Lastly, we want to determine the most appropriate test to use to determine daytime sleepiness or somnolence in patients with seasonal allergen induced congestion and daytime sleepiness.
