The objective of this double-blind trial was to evaluate the corticosteroid-sparing effect of azelastine in patients with chronic bronchial asthma. A total of 193 subjects received either 6 mg of azelastine twice per day or placebo (in a 2:1 ratio) in combination with beclomethasone dipropionate (6 to 16 inhalations per day). The number of daily inhalations of the corticosteroid was reduced until maximum reduction or elimination was achieved. Patients then entered a 12-wk maintenance period, during which patients were maintained on their lowest possible dose of inhaled corticosteroid. Compared with placebo, the azelastine group had a statistically significantly greater overall median reduction in inhaled corticosteroids (4.9 puffs/day for azelastine versus 3.1 puffs/day for placebo; p < or = 0.010) during the maintenance period. The azelastine group also had a statistically significantly higher percentage of patients with reductions of > or = 50% and > or = 75% from the baseline level (53 and 31%, respectively, for azelastine versus 34 and 14%, respectively, for placebo; p < or = 0.028). The results demonstrated that azelastine, 6 mg twice per day, can reduce the need for inhaled corticosteroids in patients with chronic bronchial asthma and not lead to a deterioration in pulmonary function.
