BMI: body mass index; CAT: COPD Assessment Test; COPD: chronic obstructive pulmonary disease; FEV1: forced expiratory volume in one second; ICS: inhaled corticosteroids (glucocorticoids); LABA: long-acting beta-agonist; LAMA: long-acting muscarinic-antagonist; mMRC: modified Medical Research Council; SABA: short-acting beta-agonist; SAMA: short-acting muscarinic-antagonist; SpO2: pulse oxygen saturation.
* Adjustments to pharmacologic therapy for COPD are based on an assessment of dyspnea/exercise limitation (mMRC or CAT), frequency of exacerbations, and peripheral blood eosinophil counts. Follow-up visits are also an opportunity to assess and reinforce nonpharmacologic interventions for COPD, including: smoking cessation; inhaler technique and adherence to medications; administration of pneumococcal and seasonal influenza vaccinations; pulmonary rehabilitation; and nutrition counselling regarding healthy diet and normal BMI. All patients with COPD should have a rapid relief inhaler available, either a SABA or a SABA-SAMA (SABA preferred for patients using a LAMA). Refer to UpToDate content on the overview of management for stable COPD.

Δ SAMAs are generally not recommended to be used routinely in conjunction with LAMAs due to cumulative anticholinergic side effects and theoretical blockage of LAMA effects by the SAMA.
◊ If the blood eosinophil count ≥300 cells/microL, patients are more likely to experience exacerbations after ICS withdrawal. Close patient monitoring is required if ICS are withdrawn.
§ Ensifentrine may reasonably be added to the regimen instead of LAMA or LABA therapy if one of these agents cannot be used due to adverse effects or other contraindication.
¥ In patients with exacerbations and blood eosinophil count ≥300 cells/microL, the addition of ICS is likely to be of benefit. For patients with eosinophil counts ≥100 but <300 cells/microL, ICS may improve exacerbation rates and pulmonary function.
‡ Ensifentrine has not been well-studied as add-on therapy to both LAMA and LABA. Until further data are available, however, the distinct mechanism of action and favorable side-effect profile of this agent drive its preferred use in this setting.
† Nonpharmacologic measures (eg, oxygen therapy if SpO2 ≤88%, pulmonary rehabilitation, bronchoscopic or surgical lung volume reduction, lung transplantation) can help reduce dyspnea and exacerbations. Contributing comorbidities should be evaluated and treated. Not all patients achieve control of dyspnea or exacerbations despite optimal available pharmacotherapy.
** For patients with a blood eosinophil count <100 cells/microL, there is a low likelihood that addition of ICS will be beneficial and higher risk of pneumonia after the addition of ICS.
¶¶ Roflumilast is used for patients with chronic bronchitis and FEV1 <50% predicted, particularly if there has been at least 1 hospitalization for an exacerbation in the past year. Potential adverse effects may limit use.
ΔΔ Azithromycin preventive therapy is more effective in patients who are not current smokers. It may lead to development of resistant organisms and may prolong the QT interval.
◊◊ Dupilumab therapy is appropriate only for patients with peripheral eosinophilia (≥300 cells/microL) or concomitant severe asthma.
