COPD: chronic obstructive pulmonary disease; ICS: inhaled corticosteroids (glucocorticoids); LABA: long-acting beta-agonist; LAMA: long-acting muscarinic antagonist; SABA: short-acting beta-agonist; SAMA: short-acting muscarinic antagonist.
* Ensifentrine may reasonably be substituted for LAMA or LABA therapy if one of these agents cannot be used due to adverse effects or other contraindications.
¶ In patients with exacerbations and blood eosinophil count ≥300 cells/microL, the addition of ICS is likely to be of benefit. Patients with eosinophil counts <100 cells/microL are less likely to experience improvements in exacerbations.
Δ For patients who are on LABA-ICS therapy, switching to LAMA-LABA-ICS rather than LAMA-LABA is a reasonable option if there has been a beneficial effect from the ICS without adverse effects.
