Clinical potential of aclidinium bromide in chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is increasing worldwide and is predicted to become the third most frequent cause of death by 2030. Muscarinic receptor antagonists, alone or in combination with long-acting β2-agonists, are frequently used for COPD therapy. Aclidinium bromide is a novel muscarinic receptor antagonist, and clinical studies indicate that its metabolism is more rapid than that of other muscarinic receptor inhibitors, so systemic side effects are expected to occur less frequently. Aclidinium bromide is well tolerated, and when compared with other muscarinic receptor antagonists, the drug achieves better control of lung function, especially night-time symptoms in COPD patients. This review summarizes the safety profile and side effects reported by recent clinical studies using aclidinium bromide alone. [ABSTRACT FROM AUTHOR]
