When Two Drugs Are Better than Three: Re-Modulating the Therapeutic Plan of a Chronic Obstructive Pulmonary Disease
Abstract:
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 β2-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.

Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
