    Author: Hanania NA.
    Journal: Clin Ther; 2007 Oct; 29(10):2121-33. PubMed ID: 18042470.
    Abstract:
    BACKGROUND: Chronic obstructive pulmonary disease (COPD) is associated with substantial morbidity and mortality. Published practice guidelines and treatment algorithms for COPD are designed to increase awareness of the problem and improve patient care; however, <40% of subjects diagnosed with COPD are receiving appropriate maintenance therapy. OBJECTIVE: This paper reviews the use of maintenance therapy in COPD and examines the optimal timing for initiating such therapy based on the available literature. METHODS: Relevant publications were identified through a search of MEDLINE (1995-May 2007) using the terms COPD, guidelines, treatment, maintenance therapy, bronchodilator, ipratropium, tiotropium, beta-agonist, salmeterol, and inhaled corticosteroid. English-language publications discussing pharmacologic maintenance therapy for COPD, including practice statements/guidelines, randomized controlled clinical trials, systematic reviews, and meta-analyses, with a focus on agents currently approved for use in the United States, were selected for inclusion. RESULTS: Although guidelines and algorithms agree on the importance of regularly scheduled maintenance therapy to reduce symptoms of COPD, minimize activity limitations, and improve health status, the timing of the initiation of such therapy is debatable. In most instances, maintenance medications, which include long-acting beta(2)-agonists, long-acting anticholinergics, and combination products, are prescribed late in the disease process and mainly for patients with severe disease. However, there is increasing evidence that the use of maintenance therapy early in the disease process may be associated with improvements in such outcomes as lung function, symptoms, exercise tolerance, exacerbations of COPD, and quality of life. CONCLUSION: The high burden associated with COPD highlights the need to initiate maintenance therapy before a substantial decline in lung function has occurred.
