Respiratory diseases antihistamines

Respiratory disease In general, antihistamines are not recommended to treat lower respiratory tract symptoms, because their anticholinergic effects may cause thickening of secretions and impair expectoration. However, several reports indicate antihistamines can be safely used in asthmatic patients with severe perennial allergic rhinitis. [Pg.803]

A large package of data, and two well-con-trolled pivotal studies of safety and efficacy are rarely required, with the exception of diseases specific to childhood, such as surfactant studies in respiratory distress syndrome. This is especially the case if the drug has similar effects in both adult and pediatric populations, for example antihistamines. [Pg.227]
