RT Journal Article SR Electronic T1 Single inhaler triple therapy for COPD JF Drug and Therapeutics Bulletin JO Drug Ther Bull FD BMJ Publishing Group Ltd SP 138 OP 141 DO 10.1136/dtb.2017.12.0562 VO 55 IS 12 YR 2017 UL http://dtb.bmj.com/content/55/12/138.abstract AB The European Medicines Agency (EMA) has granted marketing authorisation for a pressurised metered dose inhaler (pMDI) containing beclometasone dipropionate, formoterol fumarate dihydrate and glycopyrronium bromide (Trimbow – Chiesi Pharmaceuticals) for the treatment of chronic obstructive pulmonary disease (COPD) in patients not adequately treated with a combination of an inhaled corticosteroid (ICS) and a long-acting beta2 agonist (LABA).1–3 The manufacturer claims that this is a significant treatment advance for COPD patients, and that the use of one inhaler should simplify therapy and, therefore, may improve adherence.1 Here, we consider the evidence for this product for the management of patients with moderate to severe COPD, and how it fits with current management strategies.
