Abstract: Chronic obstructive pulmonary disease (COPD) is a global health challenge and a major cause of mortality worldwide. Bronchodilators, particularly long-acting β2-agonists and long-acting antimuscarinic agents, used singly or in combination, aim to improve lung function, reduce symptoms, prevent exacerbations, and enhance quality of life of COPD patients. Indacaterol is a novel, inhaled, long-acting β2-agonist, with rapid onset of action and once-daily dosing providing 24-hour bronchodilation. Currently, the recommended dose differs between Europe (150 µg; maximum 300 µg) and USA (75 µg), the latter is lower than that assessed in the majority of the conducted studies. This review summarises published evidence regarding the efficacy, tolerability, and safety of indacaterol at a dose of 75 µg. Indacaterol 75 µg was found to be superior than placebo regarding lung function, dyspnea, health status, use of rescue medication, and rate of exacerbations. Furthermore, indacaterol 75 µg was well tolerated, while the most frequent adverse effect was deterioration of COPD occurring at a frequency similar to placebo, without major cardiovascular adverse effects. In conclusion, indacaterol 75 µg, administered once daily, is efficacious and has an excellent tolerability and safety profile, and is therefore a valid alternative in the treatment of COPD patients.
