title: Ipratropium bromide in the treatment of the 'rhinorrhoea syndrome'.
abstract: Conventional treatments for non-allergic perennial rhinitis have proven somewhat unsuccessful in the control of rhinorrhoea when it is the predominant symptom. Hence, a double-blind cross-over trial of Ipratropium, a parasympatholytic, and placebo were carried out over a 12-week period. There was a significant reduction in rhinorrhoea during active treatment, with the most noticeable effect being in the moderate-to-severe rhinorrhoea group. No significant effect was noted on nasal obstruction or sneezing and no serious side-effects were seen. A carry-on effect was noted when active treatment was used initially. However, the group given active treatment following placebo had a better result overall. A strong placebo effect was also noted in both groups, in keeping with a trial of this order.
