The goals of pharmacologic management of COPD are to enhance smoking cessat
ion, alleviate dyspnea by promoting bronchodilatation, treating exacerbatio
ns, and preserving lung function. The step approach to the use of bronchodi
lators based upon the degree of dyspnea is reviewed with particular attenti
on to anticholinergic agents and beta agonists, Bronchodilators are useful
not only to improve lung function but also to enhance health-related qualit
y of life. Although inhaled steroids may prevent decline in lung function a
nd reduce the number of exacerbations, their precise role awaits completion
of further studies currently in progress. Exacerbations should be treated
with antibiotics, and the choice of agents depends upon the severity of the
underlying lung disease.
