Can we justify ipratropium therapy as initial management of acute exacerbations of COPD?
Although inhaled ipratropium is commonly accepted as the drug of choice for long-term management of chronic bronchitis and emphysema, little evidence is available to promote its administration in conjunction with a beta2-agonist as part of initial management of exacerbations of chronic obstructive pulmonary disease (COPD) in the acute care setting. Reasons for its widespread acceptance for acutely ill patients may include its status as a first-line agent for long-term therapy, its relative safety, and attempts to provide optimal patient care. Since inhaled ipratropium is beneficial as immediate therapy for asthma in the emergency department, some practitioners attempted to extrapolate these findings to treatment of COPD. Review of available studies reveals wide variability in methodologies and results. Although some studies reported improvement in pulmonary function tests, no clinically significant differences in patient outcomes, including shorter hospitalization, were evident. In patients who fail traditional therapies, inhaled ipratropium is reasonable. Double-blind, randomized, placebo-controlled trials in patients receiving emergency department care and in hospitalized patients that reveal shorter length of stay or other improved outcomes, are necessary to establish routine addition of inhaled ipratropium to beta2-agonists in the initial management of acute COPD.
