Abstract

Background and Aim:

Long-acting bronchodilators are the mainstay of pharmacological treatment for patients with chronic obstructive pulmonary disease (COPD). The aim of this review is to provide an overview of the clinical studies evaluating the safety and efficacy of inhaled aclidinium bromide, a novel long-acting anticholinergic bronchodilator, for the treatment of COPD.

Method:

This systematic review explored the efficacy and safety of aclidinium bromide in comparison with placebo and other long-acting bronchodilators for treatment of moderate to severe COPD. Randomised controlled trials were identified through systematic searches of different databases of published trials.

Results:

Ten trials (3.922 participants) were included. Aclidinium bromide appears to be a safe and well-tolerated long-acting anti-cholinergic bronchodilator with a relatively fast onset of action. Compared with other long-acting bronchodilators, including tiotropium bromide, aclidinium bromide leads to at least similar clinically important improvements in level of FEV1, health status, use of rescue medication, and day-time dyspnea scores in patients suffering from moderate to severe COPD. With twice-daily dosing, aclidinium bromide may have clinically important effect on night-time symptom scores in COPD patients, but further studies are needed in order to permit valid conclusions with regard to this point. The effect of aclidinium bromide on exercise tolerance, as assessed by exercise endurance time, and dynamic hyperinflation in patients with moderate to severe COPD seems to be at least comparable to other long-acting bronchodilators, incl. tiotropium bromide and indacaterol. Aclidinium bromide might reduce the rate of exacerbations in COPD patients, but conclusions must await further long-term controlled trials.

Conclusion:

Aclidinium bromide has effects on relevant COPD outcome measures, including level of FEV1, similar to other long-acting bronchodilators, and therefore seems to have the potential for a significant role in the future management of moderate to severe COPD.
