Patients with COPD were randomly assigned to triple inhaled therapy with either a 160-μg or 320-μg dose of budesonide or to one of two dual therapies. Both triple regimens were superior to the dual regimens with respect to the rate of moderate or severe exacerbations; no difference was observed between the triple regimens.

In this trial, patients with mild asthma used albuterol alone as needed, inhaled budesonide maintenance therapy plus albuterol as needed, or an inhaler containing both budesonide and formoterol as needed for asthma symptoms. There were fewer exacerbations in both groups in which treatment included budesonide.

This large trial involving children with asthma examined whether the addition of a long-acting beta-agonist to current therapy with inhaled glucocorticoids affected asthma control in children. The primary safety end point was within the prespecified noninferiority margin. The safety of inhaled beta-agonists in patients with asthma has been debated since the 1960s. 1 – 5 After the introduction of long-acting beta-agonists (LABAs) in the 1990s and the findings of two studies involving adults, attention focused on a potential association of LABAs with an increased risk of asthma-related death. 6 , 7 A 2008 meta-analysis conducted by the Food and Drug Administration (FDA) showed a higher risk of asthma-related events (death, intubation, or hospitalization) among patients receiving LABAs than among patients not receiving these medications. 8 In a subsequent meta-analysis, a higher risk of serious asthma-related events was observed with salmeterol than with . . .

In a randomized trial, as-needed albuterol–budesonide resulted in a lower risk of severe asthma exacerbation than as-needed albuterol among participants with disease that was uncontrolled despite treatment for mild asthma.

An important goal in the treatment of COPD is the prevention of exacerbations. In this trial, the investigators found that treatment with tiotropium, as compared with salmeterol, prolonged the time to the first exacerbation of COPD and decreased the number of exacerbations. Chronic obstructive pulmonary disease (COPD) is a leading cause of disability and death worldwide. 1 – 3 Exacerbations of COPD indicate instability or worsening of the patient's clinical status and progression of the disease and have been associated with the development of complications, an increased risk of subsequent exacerbations, a worsening of coexisting conditions, reduced health status and physical activity, deterioration of lung function, and an increased risk of death. 4 – 7 The prevention of exacerbations therefore constitutes a major goal of treatment. 1 , 2 Therapy with a long-acting anticholinergic drug or a long-acting β 2 -agonist is recommended as first-line maintenance therapy in . . .

In a previous randomised controlled phase 2 trial, intravenous infusion of salbutamol for up to 7 days in patients with acute respiratory distress syndrome (ARDS) reduced extravascular lung water and plateau airway pressure. We assessed the effects of this intervention on mortality in patients with ARDS. We did a multicentre, placebo-controlled, parallel-group, randomised trial at 46 UK intensive-care units between December, 2006, and March, 2010. Intubated and mechanically ventilated patients (aged ≥16 years) within 72 h of ARDS onset were randomly assigned to receive either salbutamol (15 μg/kg ideal bodyweight per h) or placebo for up to 7 days. Randomisation was done by a central telephone or web-based randomisation service with minmisation by centre, pressure of arterial oxygen to fractional inspired oxygen concentration (PaO 2/F IO 2) ratio, and age. All participants, caregivers, and investigators were masked to group allocation. The primary outcome was death within 28 days of randomisation. Analysis was by intention-to-treat. This trial is registered, ISRCTN38366450 and EudraCT number 2006-002647-86. We randomly assigned 162 patients to the salbutamol group and 164 to the placebo group. One patient in each group withdrew consent. Recruitment was stopped after the second interim analysis because of safety concerns. Salbutamol increased 28-day mortality (55 [34%] of 161 patients died in the salbutamol group vs 38 (23%) of 163 in the placebo group; risk ratio [RR] 1·47, 95% CI 1·03–2·08). Treatment with intravenous salbutamol early in the course of ARDS was poorly tolerated. Treatment is unlikely to be beneficial, and could worsen outcomes. Routine use of β-2 agonist treatment in ventilated patients with this disorder cannot be recommended. UK Medical Research Council, UK Department of Health, UK Intensive Care Foundation.

In adolescents and adults with moderate-to-severe asthma, the addition of formoterol to inhaled glucocorticoids was associated with a lower risk of asthma exacerbations than that with glucocorticoids alone and with a similar risk of serious asthma-related events. Current guidelines for the management of asthma suggest that inhaled glucocorticoids should be used as initial controller therapy, with a long-acting beta-agonist (LABA) then added if symptoms remain uncontrolled or increase in severity. 1 Although LABAs have been an available treatment option for asthma since 1990, 2 questions remain regarding the safety of this drug class. 3 These concerns originate mainly from the results of two large studies in which the effects of adding the LABA salmeterol to existing asthma treatment were reviewed. 4 , 5 These studies showed higher rates of asthma-related death and other serious outcomes related to asthma among patients receiving salmeterol . . .

The current Global initiative for chronic Obstructive Lung Disease (GOLD) treatment strategy recommends the use of one or more bronchodilators according to the patient's airflow limitation, their history of exacerbations, and symptoms. The LANTERN study evaluated the effect of the long-acting β2-agonist (LABA)/long-acting muscarinic antagonist (LAMA) dual bronchodilator, QVA149 (indacaterol/glycopyrronium), as compared with the LABA/inhaled corticosteroid, salmeterol/fluticasone (SFC), in patients with moderate-to-severe COPD with a history of ≤1 exacerbation in the previous year. In this double-blind, double-dummy, parallel-group study, 744 patients with moderate-to-severe COPD with a history of ≤1 exacerbations in the previous year were randomized (1:1) to QVA149 110/50 μg once daily or SFC 50/500 μg twice daily for 26 weeks. The primary endpoint was noninferiority of QVA149 versus SFC for trough forced expiratory volume in 1 second (FEV1) at week 26. Overall, 676 patients completed the study. The primary objective of noninferiority between QVA149 and SFC in trough FEV1 at week 26 was met. QVA149 demonstrated statistically significant superiority to SFC for trough FEV1 (treatment difference [Δ]=75 mL; P<0.001). QVA149 demonstrated a statistically significant improvement in standardized area under the curve (AUC) from 0 hours to 4 hours for FEV1 (FEV1 AUC0-4h) at week 26 versus SFC (Δ=122 mL; P<0.001). QVA149 and SFC had similar improvements in transition dyspnea index focal score, St George Respiratory Questionnaire total score, and rescue medication use. However, QVA149 significantly reduced the rate of moderate or severe exacerbations by 31% (P=0.048) over SFC. Overall, the incidence of adverse events was comparable between QVA149 (40.1%) and SFC (47.4%). The incidence of pneumonia was threefold lower with QVA149 (0.8%) versus SFC (2.7%). These findings support the use of the LABA/LAMA, QVA149 as an alternative treatment, over LABA/inhaled corticosteroid, in the management of moderate-to-severe COPD patients (GOLD B and GOLD D) with a history of ≤1 exacerbation in the previous year.

Background In mild asthma exercise-induced bronchoconstriction (EIB) is usually treated with inhaled short-acting β2 agonists (SABAs) on demand. Objective The hypothesis was that a combination of budesonide and formoterol on demand diminishes EIB equally to regular inhalation of budesonide and is more effective than terbutaline inhaled on demand. Methods Sixty-six patients with asthma (>12 years of age) with verified EIB were randomised to terbutaline (0.5 mg) on demand, regular budesonide (400 μg) and terbutaline (0.5 mg) on demand, or a combination of budesonide (200 μg)  + formoterol (6 μg) on demand in a 6-week, double-blind, parallel-group study (ClinicalTrials.gov identifier: NCT00989833). The patients were instructed to perform three to four working sessions per week. The main outcome was EIB 24 h after the last dosing of study medication. Results After 6 weeks of treatment with regular budesonide or budesonide+formoterol on demand the maximum post-exercise forced expiratory volume in 1 s fall, 24 h after the last medication, was 6.6% (mean; 95% CI −10.3 to −3.0) and 5.4% (−8.9 to −1.8) smaller, respectively. This effect was superior to inhalation of terbutaline on demand (+1.5%; −2.1 to +5.1). The total budesonide dose was approximately 2.5 times lower in the budesonide+formoterol group than in the regular budesonide group. The need for extra medication was similar in the three groups. Conclusions The combination of budesonide and formoterol on demand improves asthma control by reducing EIB in the same order of magnitude as regular budesonide treatment despite a substantially lower total steroid dose. Both these treatments were superior to terbutaline on demand, which did not alter the bronchial response to exercise. The results question the recommendation of prescribing SABAs as the only treatment for EIB in mild asthma.

Background Combining two long-acting bronchodilators with complementary mechanisms of action may provide treatment benefits to patients with chronic obstructive pulmonary disease (COPD) that are greater than those derived from either treatment alone. The efficacy and safety of a fixed-dose combination (FDC) of aclidinium bromide, a long-acting muscarinic antagonist, and formoterol fumarate, a long-acting β 2 -agonist, in patients with moderate to severe COPD are presented. Methods In this 24-week double-blind study, 1692 patients with stable COPD were equally randomized to twice-daily treatment with FDC aclidinium 400μg/formoterol 12μg (ACL400/FOR12 FDC), FDC aclidinium 400μg/formoterol 6μg (ACL400/FOR6 FDC), aclidinium 400μg, formoterol 12μg, or placebo administered by a multidose dry powder inhaler (Genuair ® /Pressair ® )*. Coprimary endpoints were change from baseline to week 24 in 1-hour morning postdose FEV 1 (FDCs versus aclidinium) and change from baseline to week 24 in morning predose (trough) FEV 1 (FDCs versus formoterol). Secondary endpoints were change from baseline in St. George’s Respiratory Questionnaire (SGRQ) total score and improvement in Transition Dyspnea Index (TDI) focal score at week 24. Safety and tolerability were also assessed. Results At study end, improvements from baseline in 1-hour postdose FEV 1 were significantly greater in patients treated with ACL400/FOR12 FDC or ACL400/FOR6 FDC compared with aclidinium (108 mL and 87 mL, respectively; p < 0.0001). Improvements in trough FEV 1 were significantly greater in patients treated with ACL400/FOR12 FDC versus formoterol (45 mL; p = 0.0102), a numerical improvement of 26 mL in trough FEV 1 over formoterol was observed with ACL400/FOR6 FDC. Significant improvements in both SGRQ total and TDI focal scores were observed in the ACL400/FOR12 FDC group at study end (p < 0.0001), with differences over placebo exceeding the minimal clinically important difference of ≥4 points and ≥1 unit, respectively. All treatments were well tolerated, with safety profiles of the FDCs similar to those of the monotherapies. Conclusions Treatment with twice-daily aclidinium 400μg/formoterol 12μg FDC provided rapid and sustained bronchodilation that was greater than either monotherapy; clinically significant improvements in dyspnea and health status were evident compared with placebo. Aclidinium/formoterol FDC may be an effective and well tolerated new treatment option for patients with COPD.
