Aerosol beclomethasone in patients with steroid-responsive chronic obstructive pulmonary disease.
Some patients with chronic obstructive pulmonary disease have favorable responses to treatment with oral corticosteroids with increase in one-second forced expiratory volume of 30 percent or more above the baseline. The benefit of long-term steroid therapy may be outweighed by the side effects. Twelve patients who had previously demonstrated a response to oral corticosteroids were studied in a double-blind randomized crossover trial comparing prednisone (30 mg daily) with beclomethasone (metered-dose inhaler, 16 puffs daily) for two weeks each with a two-week washout period between the two regimens. Those who were taking prednisone tapered the dose to 5 mg daily and those taking beclomethasone discontinued it for two weeks before the beginning of the study. History, physical examination, and pulmonary function were monitored. The mean one-second forced expiratory volume increased from 0.65 to 1.00 liter after prednisone therapy and it increased from 0.63 to 0.81 liter after aerosol beclomethasone (difference significant, p less than 0.01 by paired t test). Only five of 12 patients had an increase in one-second forced expiratory volume with steroid aerosol, an increase that was at least 50 percent that achieved by prednisone. In most patients with steroid-responsive chronic obstructive pulmonary disease, aerosol beclomethasone is not an adequate substitute for oral steroids.[1]References
