Some people with nasal allergy symptoms continue to have symptoms even after treatment with
a nasal steroid spray. The purpose of this study is to see if these patients are helped by
adding another medication (montelukast) to their treatment compared to placebo (a substance
that looks like the active medication but does not contain the drug).
Clinicians frequently prescribe an oral H1 antihistamine for allergic rhinitis patients with
residual symptoms after taking an intranasal steroid. Surprisingly, the only studies
investigating this combination of drugs have failed to show added efficacy of the H1
receptor over the intranasal steroids alone. Adding montelukast, a leukotriene receptor
antagonist, to an intranasal steroid has not been studied in a placebo controlled fashion.
Wilson and colleagues, in an open study of patients with chronic rhinosinusitis, showed a
benefit of adding montelukast.
The investigators would like to recruit perennially allergic subjects and place them on
fluticasone for 2 weeks. Those subjects with residual symptoms would then be randomized to
receive either placebo or montelukast in addition to continuing the fluticasone for an
additional 2 weeks.
A positive study would support clinical practice and would serve as a preemptive strike
against managed care plans that would not allow prescriptions for both drugs.
The addition of montelukast to treatment of a perennially allergic subject with an
intranasal steroid is more effective at relieving symptoms than a placebo.
- A clinical history of perennial allergic rhinitis and a positive skin prick test to
dust mite, cockroach, mold, or cat or dog antigens.
- Willingness of the subject to participate in and complete the study, and the ability
to understand the purpose of the trial.
- Physical signs or symptoms suggestive of renal, hepatic or cardiovascular disease.
- Women of childbearing potential who are pregnant, trying to become pregnant or
nursing a child.
- Subjects treated with systemic steroids during the previous 30 days.
- Subjects treated with topical (inhaled, intranasal or intraocular) steroids,
Nasalcrom or Opticrom during the previous 15 days.
- Subjects treated with oral antihistamines/decongestants during the previous seven
- Subjects treated with topical (intranasal or intraocular)
antihistamines/decongestants during the previous 3 days.
- Subjects treated with immunotherapy who are escalating their dose.
- Subjects on chronic anti-asthma medications.
- Subjects with polyps in the nose or a significantly displaced septum.
- Subjects who have incurred an upper respiratory tract infection within 14 days of the
start of the study.
