The efficacy of adding budesonide/formoterol to ipratropium plus theophylline in managing severe chronic obstructive pulmonary disease: an open-label, randomized study in China

Abstract

Patients with severe COPD in China treated with BUD/FORM plus I+T showed significant improvements in lung function and HRQoL and a reduction in exacerbations compared with I+T alone. Both treatments were well tolerated and no safety concerns were noted. <i>The reviews of this paper are available via the supplemental material section</i>.
