Pharmacotherapy of chronic obstructive pulmonary disease

Despite a significant reduction in cigarette consumption, chronic obstructive pulmonary disease continues to be an important cause of mortality in the United States. COPD is characterized by progressive airflow obstruction which is punctuated by acute exacerbations. Nicotine substitution and use of bupropion have been shown to double long-term smoking cessation success. The combination of albuterol and ipratropium bromide produces a synergistic beneficial effect on pulmonary function and symptoms. Long-acting inhaled beta 2-agonists improve symptoms better than as needed albuterol. Oral corticosteroids appear to be helpful during acute exacerbations; however, the chronic use of steroids benefits only a minority of patients. Broad- spectrum antibiotics are indicated during acute exacerbations if there is increased sputum volume and purulence. System-oriented administration of pneumococcal and influenza vaccinations is more successful than provider or client-oriented approaches.
