Acute exacerbations of obstructive lung disease.

Preview Because they are rapidly effective, inhaled beta2 agonists are the cornerstone of therapy in patients having an acute exacerbation of obstructive lung disease. In addition, inhaled anticholinergics, methylxanthines, systemic corticosteroids, and antibiotics are useful in appropriate situations. The authors describe assessment of these patients (who may be critically ill at presentation), provide recommendations for conventional therapy, and summarize alternative methods.
