A comparison between inhaled salmeterol and theophylline in the short-term treatment of stable chronic obstructive pulmonary disease

Inhaled salmeterol improves lung function in stable patients with moderate-to-severe and poorly reversible COPD. The magnitude of improvement in FEV1 observed in this study is similar to that found in longer and larger studies on similar populations of patients. In those studies, that improvement was associated with a better quality of life and less symptoms. Theophylline determined a smaller improvement in FEV1 with more unpleasant side effects that both doses of inhaled salmeterol, though there was no significant difference. It is concluded that salmeterol is an effective and well tolerated therapy, potentially preferable to theophylline, at least in the short-term management of stable COPD.
