Title: The effect of locally applied ipratropium aerosol on the nasal methacholine challenge in patients with allergic and non-allergic rhinitis. Author: Sanwikarja S, Schmitz PI, Dieges PH. Journal: Ann Allergy; 1986 Feb; 56(2):162-6. PubMed ID: 2936282. Abstract: The effect of local pretreatment with ipratropium versus placebo aerosol on nasal methacholine challenge was studied in a double-blind, crossover trial. Fourteen allergic and ten non-allergic patients suffering from rhinitis participated in this study. It can be concluded that intranasal administration of ipratropium has a suppressive effect on hypersecretion and sneezing, but has no influence on nasal airway resistance.[Abstract] [Full Text] [Related] [New Search]
