Some studies have concluded that high-dose inhaled steroids (IS) are effective in the clinical control of patients with bronchiectasis, however the high doses needed provokes some adverse effects and lower doses are not effective. Combined treatment with budesonide and formoterol have demostrated to be effective in patients with asthma and COPD achieving the reduction of steroid dose thanks to the adition of a long-acting beta 2 agonists. There are no studies in the literature analysing the effect of combined treatment in patients with bronchiectasis. The objective of this study is to compare the efficacy and safety of formoterol-medium dose of budesonide in a single inhaler versus high-dose of budesonide in the clinical control of patientes with non-cystic fibrosis bronchiectasis.
