Aclidinium bromide (INN) is a long-acting, inhaled muscarinic antagonist approved in the US on July 24, 2012[1] as a maintenance treatment for chronic obstructive pulmonary disease (COPD).[2]

Evidence shows that it can improve quality of life and prevent hospitalization in those with COPD.[3] However, it does not appear to affect the risk of death or the frequency steroids are needed.[3] It is unclear if it differs from the similar medication tiotropium or another commonly used medication class of LAMAs.[3]

Aclidinium is delivered via a, multidose dry powder inhaler, the Genuair inhaler.

Brand names

It is marketed under the brand name Tudorza Pressair in the US, Eklira Genuair in the UK, and Tudorza Genuair in Canada; licensed to Menarini under the brand name Bretaris Genuair for majority of EU member states[4]
