Abstract

Inhaled beclomethasone dipropionate is now well established in the management of asthma. Studies conducted over the last decade, and since the drug was previously reviewed in the Journal, have confirmed that inhaled beclomethasone dipropionate 400 to 800 micrograms daily can reduce the need for oral maintenance corticosteroids in the majority of asthmatic patients requiring such therapy, and that increasing the dosage to 2000 micrograms daily may provide additional clinical benefit in some patients unresponsive to usual therapeutic dosages. Follow-up over a period of several years has confirmed that the initial response to inhaled beclomethasone can be maintained in most patients. Recent studies indicate that beclomethasone dipropionate 400 micrograms daily is equally effective when administered in 2 or 4 divided doses in patients with stable asthma, but it is likely that the lower frequency of administration will be less effective when the asthma is unstable. Recent studies have established the usefulness and good tolerability of intranasal beclomethasone dipropionate in the treatment of perennial and seasonal rhinitis, where the drug has been shown to be more effective than intranasal sodium cromoglycate and similar in efficacy to flunisolide. Nasal polyps decrease in size during continuous treatment with intranasal beclomethasone dipropionate, but enlarge again during periods of respiratory infection. After a decade of treatment with inhaled and intranasal beclomethasone dipropionate, there is no evidence that the drug damages the tracheobronchial lining or the nasal mucosa. Thus, the initial promise of beclomethasone dipropionate has been fulfilled. It has had an important role in asthma therapy over the past decade, which will continue into the future.
