Current Evidence on the Usefulness of Potential Therapies in the Prevention of COPD Exacerbations: Beyond the Use of Bronchodilator Therapy and Inhaled Corticosteroids

Prevention of exacerbations is a key objective in chronic obstructive pulmonary disease (COPD) management. The adverse effects of an exacerbation include a negative impact on patient quality of life and symptoms, an accelerated rate of decline in lung function, hospital admissions, and increased mortality. Clinical guidelines related to COPD management recommend smoking cessation and inhaled therapy (bronchodilators with or without corticosteroids) as the mainstay for these patients. Apart from the above-mentioned treatment, other potential therapies, such as mucolytic agents, antibiotics (oral or inhaled), phosphodiesterase-4 inhibitors or vaccination, are available and have been shown to reduce the incidence of exacerbations. In this brief narrative review, we will examine the efficacy of various treatments for preventing COPD exacerbations, beyond the use of bronchodilator therapy and inhaled corticosteroids.
