Kartik V. Shenoy, MD, Professor of Thoracic Medicine and Surgery at the Lewis Katz School of Medicine at Temple University, provided perspective to MedPage Today for an article on new research presented at the CHEST Annual Meeting in Chicago which showed that in two randomized trials, a fixed-dose inhaler combining an inhaled corticosteroid, long-acting muscarinic antagonist, and long-acting beta agonist (ICS/LAMA/LABA) improved lung function and reduced exacerbations in poorly controlled asthma compared with an ICS/LABA inhaler. Shenoy was not involved in the research.
