A review of current and developing fixed-dose LABA/LAMA combinations for treating COPD

INTRODUCTION: The current GOLD (Global Initiative for Chronic Obstructive Lung Disease) recommendations suggest using long acting β2 agonists (LABA) and long acting muscarinic antagonists (LAMA) in combination for group B COPD patients with persistent symptoms, group C COPD patients with further exacerbations on LAMA therapy alone and for group D COPD patients with or without combination with inhaled corticosteroids (ICS). Thus, there is a lot of interest in developing LABA/LAMA combinations for maintenance therapy of chronic stable COPD. Areas covered: Many LABA/LAMA combinations have successfully been approved through carefully designed pivotal clinical trials. The current clinical use of LABA/LAMA combinations in COPD will continue to evolve as new trials with and without inhaled corticosteroids are completed. Expert opinion: Combining different classes of bronchodilators in a single inhaler is an attractive concept that can potentially improve patient adherence to therapy. Because LABA/LAMA combinations are the preferred treatment option for preventing COPD exacerbations in the updated GOLD guidelines for COPD, they will be clinically used. Future treatment of COPD should revolve around a personalized approach based on characterization of the COPD phenotype.
