According to disease severity in individual patients, exacerbations and comorbidities frequently occur. The overall nocturnal and daily symptoms have a strong impact on patient quality of life and clinical outcomes. Bronchodilators, by targeting two important aspects of COPD pathophysiology, ie, bronchoconstriction and lung hyperinflation, are the mainstay of therapy for COPD. Aclidinium bromide in particular is an anticholinergic molecule, approved for maintenance bronchodilator treatment of stable COPD, that combines high antimuscarinic activity with strong kinetic selectivity for the M3 receptor subtype. Moreover, the elevated plasma clearance of aclidinium has been related to low systemic bioavailability and low incidence of anticholinergic adverse events, whereas the reduced residence time at M2 receptors provides good cardiovascular safety. Altogether, these characteristics result in a high safety and tolerability profile. This review aims to reappraise the contribution of symptoms and of the level of quality of life determinants on COPD severity and to evaluate how therapeutic strategies with aclidinium may positively impact on these specific determinants of disease severity.
