| Abstract: | Patients with a history of nonallergic perennial secretory rhinitis of many years' duration were selected for a comparative study investigating the effects of the topical application of ipratropium (an anticholinergic drug) and budesonide (a glucocorticoid). According to the patient's daily registration of nasal symptoms, there was a significant effect of budesonide on nasal secretion and sneezes. Since budesonide proved superior to ipratropium, it is concluded that the secretion in this type of rhinitis might be regulated by mechanisms other than cholinergic. |
