Pharmacologic treatment options of COPD aim to reduce symptoms, improve exercise tolerance, improve health status and prevent exacerbations. 1 Knowing that smoking cessation is the only approach that can delay the progressive decline in lung function, bronchodilators use can still help patients retain their ability to engage in normal activities which they would otherwise lose while becoming sedentary to avoid dyspnea. 4 The primary physiological abnormality in COPD is an accelerated decline in the force expiratory volume in one second (FEV1) from the normal decline rate in adults (over 30 years) of approximately 30 mL/year to nearly 60 mL/year. 3 Among common symptoms of COPD, dyspnoea is known to be the most stressful symptom as it affects the ability of patients to undergo normal daily activities. 2 COPD patients complain usually of chronic cough, dyspnoea, sputum, wheezing and chest tightness. 1 It is characterized by persistent respiratory symptoms and airflow limitation and obstruction due to the chronic inflammation of airways and lung parenchyma, which eventually interferes with the normal breathing process. However, further studies comparing umeclidinium/vilanterol FDC (ANORO) to other LABA/LAMA combinations are needed.Ĭhronic obstructive pulmonary disease (COPD) is a common, progressively disabling disease that is predicted to be the third leading cause of death worldwide by 2030. Clinical data published on the combination of umeclidinium/vilanterol in patients with COPD have shown greater improvements in lung function compared to monotherapies. The search was limited to English language studies on human subjects. 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. Literature search was done through PubMed (2004-2017) using the terms umeclidinium, vilanterol, COPD, LABA and LAMA. 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. 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. 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. Chronic obstructive pulmonary disease (COPD) is a common respiratory disease that is predicted to be one of the leading causes of death worldwide.
