This article reviews the role of anticholinergic therapy for the rhinorrhea that occurs in various rhinopathies, including irritant reactions, perennial nonallergic rhinitis, viral infection rhinitis, allergic rhinitis, and temperature-induced rhinitis. The use of a topical anticholinergic medication, ipratropium bromide, and its ability to inhibit methacholine and rhinitis-induced hypersecretion is emphasized. Ipratropium bromide appears to be both safe and effective in reducing this troublesome symptom.
