Abstract
ABSTRACTIntroduction: Treatment options for COPD have evolved rapidly in the last decade and inhaled bronchodilators have largely supplanted the use of oral bronchodilators because of their increased efficacy and excellent safety with topical delivery to the lung. Recently added to the therapeutic armamentarium are fixed-dose combinations (FDC) of two long acting bronchodilators. LAMAs (long acting muscarinic antagonists) and LABAs (long acting beta agonists) are the main classes available and use different pathways to effectively produce bronchial smooth muscle relaxation.Areas covered: The most recent inhaled FDC LAMA/LABA to come to market is Aclidinium Bromide and Formoterol Fumarate. We searched databases of PubMed, Cochrane Library, and manufacturers’ websites and retrieved all the randomized-controlled trials (RCTs) conducted with these drugs up to September 2019.Expert opinion: It is likely that FDCs will become the core of our COPD pharmacotherapy for all but the mildest COPD patients. These individual drugs have excellent efficacy and safety records for the maintenance treatment of COPD. Studies have demonstrated that twice daily treatment with aclidinium/formoterol resulted in significant improvement in lung function and an improved exercise tolerance when compared to placebo. Adverse effects are within the range of what is seen with other LAMA/LABA combinations.
