GOLD 3 Severe 30 – 49%
GOLD 4 Very Severe <30%

FEV1 – Forced expiratory volume in 1 second

 

Escalation of Long-Term COPD Therapy

Step 1: Long Acting Bronchodilator Monotherapy (i.e. LAMA or LABA)
Long-Acting Muscarinic Antagonists (LAMA’s) – tiotropium, glycopyrronium, aclidinium
Long-Acting Beta2 Agonists (LABA’s) – formoterol, salmeterol, indacaterol

Step 2: LAMA + LABA
e.g. Spiolto (olodaterol + tiotropium), Anoro (vilanterol + umeclidinium)

Step 3 :Inhaled corticosteroid (ICS) + LAMA + LABA
e.g. Trelegy (fluticasone + umeclidinium + vilanterol), Spiriva (tiotropium) + Seretide (Fluticasone + salmeterol)
