Randomized Controlled Trial Comparative Study
24-hour bronchodilator efficacy of single doses of indacaterol in subjects with COPD: comparison with placebo and formoterol.
To assess the bronchodilator efficacy, safety and tolerability of indacaterol, a novel, once-daily inhaled beta(2)-agonist bronchodilator, in patients with chronic obstructive pulmonary disease (COPD). ⋯ All doses of indacaterol were effective in providing 24-h bronchodilation and were well-tolerated in subjects with COPD. The bronchodilator efficacy of indacaterol (150, 300 and 600 microg) at 24 h post-dose was at least as efficacious as formoterol 12 microg twice daily.
