AbstractChronic obstructive pulmonary disease (COPD) is a common respiratory disease that is predicted to be one of the leading causes of death worldwide. Pharmacologic treatment options of COPD are bronchodilators, using either long-acting β2-agonists (LABAs), or long-acting muscarinic antagonists (LAMAs), or a combination of two. Anoro Ellipta (umeclidinium + vilanterol) dry powder inhaler, a fixed-dose combination of LAMA and LABA, was Food and Drug Administration (FDA) approved in 2013 for COPD. The objective of this study is to evaluate the efficacy and safety of once daily umeclidinium/vilanterol (62.5 mcg/25 mcg) in COPD patients, focusing on pharmacodynamic and pharmacokinetic characteristics, efficacy and safety in clinical studies and cost. Literature search was done through PubMed (2004-2017) using the terms umeclidinium, vilanterol, COPD, LABA and LAMA. Recent and significant clinical trials about the monocomponents and their combination were identified, in addition to reviews, guidelines for COPD, data from manufacturer and FDA product labels. The search was limited to English language studies on human subjects. Clinical data published on the combination of umeclidinium/vilanterol in patients with COPD have shown greater improvements in lung function compared to monotherapies. However, further studies comparing umeclidinium/vilanterol FDC (ANORO) to other LABA/LAMA combinations are needed.© 2019 John Wiley & Sons Ltd.
