Maintenance therapy with budesonide and formoterol in chronicobstructive pulmonary disease

Calverley, P.M., Boonsawat, W., Cseke, Z., Zhong, N., Peterson, S., Olsson, H.·2003·European Respiratory Journal

Abstract

Lung function in chronic obstructive pulmonary disease (COPD) can be improved acutely by oral corticosteroids and bronchodilators. Whether clinical improvement can be maintained by subsequent inhaled therapy is unknown. COPD patients (n=1,022, mean prebronchodilator forced expiratory volume in one second (FEV 1) 36% predicted) initially received formoterol (9 µg b.i.d.) and oral prednisolone (30 mg o.d.) for 2 weeks. After this time, patients were randomised to b.i.d.inhaled budesonide/formoterol 320/9 µg, budesonide 400 µg, formoterol 9 µg or placebo for 12 months. Postmedication FEV 1 improved by 0.21 L and health-related quality of life using the St George's Respiratory Questionnaire (SGRQ) by 4.5 units after run-in. Fewer patients receiving budesonide/formoterol withdrew from the study than those receiving budesonide, formoterol or placebo. Budesonide/formoterol patients had a prolonged time to first exacerbation (254 versus 96 days) and maintained higher FEV 1(99%versus 87% of baseline), both primary variables versus placebo. They had fewer exacerbations (1.38 versus 1.80 exacerbations per patient per year), had higher prebronchodilator peak expiratory flow, and showed clinically relevant improvements in SGRQ versus placebo (−7.5 units). Budesonide/formoterol was more effective than either monocomponent in both primary variables. Budesonide/formoterol in a single inhaler (Symbicort®) maintains the benefit of treatment optimisation, stabilising lung function and delaying exacerbations more effectively than either component drug alone or placebo.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
