The purpose of this study is to evaluate the potential cardiovascular safety concerns and all-cause mortality described in the risk management plan for aclidinium bromide, through sequential, nested case-control studies for each endpoint of interest


This is a post-authorisation safety study (PASS) of new users of aclidinium bromide, fixed dose aclidinium bromide/formoterol fumarate dihydrate, and other inhaled medications frequently used by patients with COPD.

The plan is for the PASS study to be conducted on one population-based automated health database; the initial candidate database is the CRPD in the United Kingdom.
