[Budesonide/formoterol in the treatment of COPD].
Two large, 12-month clinical trials have been performed with budesonide-formoterol in patients with stable COPD and have shown clear data on the efficacy of this combination in improving pulmonary function, symptoms and health-related quality of life and in reducing the number of exacerbations. Before these trials, information was already available on the efficacy of both monocomponents in this disease, although the main clinical data obtained with formoterol and budesonide separately in the treatment of COPD come from the respective branches of these drugs in the two large clinical trials described in the present article. Improvement in pulmonary function variables [forced expiratory volume in one second (FEV1), forced vital capacity (FVC) and peak expiratory flow (PEF)] was always greater with the combination of budesonide-formoterol. The scores obtained in quality of life questionnaires were also more favorable in the combination treatment branches as early as the first week of treatment and persisted at 12 months of follow-up. Improvement in symptoms and in the use of reliever medication was also greater in the combination branch. The frequency of mild and severe exacerbations, as well as the use of oral corticosteroids, was lower in the budesonide-formoterol branch. The time to first exacerbation was also more prolonged in this group. The present review discusses the main findings on the efficacy of the combination of budesonide-formoterol in stable COPD.
