When Two Drugs Are Better than Three: Re-Modulating the Therapeutic Plan of a Chronic Obstructive Pulmonary Disease Patient

We present the case of a 77-year-old man diagnosed with chronic obstructive pulmonary disease (COPD) stage D with emphysema phenotype and treated with triple therapy (salmeterol, fluticasone propionate, and tiotropium) for 1 year without relevant improvements in exertional dyspnea and disease impact. After switching to combination therapy with a long-acting beta(2)-agonist (LABA) and a long-acting muscarinic antagonist (LAMA) (indacaterol/glycopyrronium), we observed, in a 3-month period, a substantial reduction of the modified Medical Research Council (mMRC) dyspnea scale and COPD Assessment Test (CAT) scores. Moreover, the patient reported a reduction of dynamic hyperinflation and an improvement of ventilatory response to exercise. (C) 2018 S. Karger AG, Basel
