Placebo-Montelukast-Nedocromil-Mometasone
Over the course of four 3-day treatment regimens, participants received a single dose of each drug starting with placebo, crossover of nedocromil or montelukast, crossover of nedocromil or montelukast, ending with mometasone; with a 20-day washout between each of the four treatment periods.
