Indacaterol is a long-acting β2-adrenoceptor agonist that is available in the EU for the maintenance treatment of airflow obstruction in adult patients with chronic obstructive pulmonary disease (COPD).
Indacaterol has a 24-hour bronchodilatory effect, which allows for once-daily administration. The onset of bronchodilation after inhalation of indacaterol is fast, with significant improvements versus placebo seen 5 minutes after inhalation.
In four large (n > 400), randomized, double-blind, placebo-controlled, multicentre phase III trials, patients with COPD who received indacaterol 150 or 300 μg once daily had a significantly higher mean trough forced expiratory volume in 1 second (FEV1) than placebo recipients after 12 weeks.
Trough FEV1 differences between indacaterol and placebo recipients were 130–180 mL and exceeded the clinically relevant threshold of 120 mL in all trials. Furthermore, indacaterol recipients had significantly higher mean trough FEV1 values after 12 weeks than patients who received formoterol, salmeterol or open-label tiotropium.
COPD exacerbations and symptoms, and health-related quality of life were also significantly improved for indacaterol versus placebo recipients in some studies.
Indacaterol was generally well tolerated by adults with moderate to severe COPD.
