Among patients with moderate-to-severe asthma who were receiving a range of inhaled glucocorticoid maintenance therapies, the risk of severe asthma exacerbation was significantly lower with as-needed use of a fixed-dose combination of 180 μg of albuterol and 160 μg of budesonide than with albuterol alone.

For most patients, asthma is not controlled as defined by guidelines; whether this is achievable has not been prospectively studied. A 1-year, randomized, stratified, double-blind, parallel-group study of 3,421 patients with uncontrolled asthma compared fluticasone propionate and salmeterol/fluticasone in achieving two rigorous, composite, guideline-based measures of control: totally and well-controlled asthma. Treatment was stepped-up until total control was achieved (or maximum 500 microg corticosteroid twice a day). Significantly more patients in each stratum (previously corticosteroid-free, low- and moderate-dose corticosteroid users) achieved control with salmeterol/fluticasone than fluticasone. Total control was achieved across all strata: 520 (31%) versus 326 (19%) patients after dose escalation (p < 0.001) and 690 (41%) versus 468 (28%) at 1 year for salmeterol/fluticasone and fluticasone, respectively. Asthma became well controlled in 1,071 (63%) versus 846 (50%) after dose escalation (p < 0.001) and 1,204 (71%) versus 988 (59%) at 1 year. Control was achieved more rapidly and at a lower corticosteroid dose with salmeterol/fluticasone versus fluticasone. Across all strata, 68% and 76% of the patients receiving salmeterol/fluticasone and fluticasone, respectively, were on the highest dose at the end of treatment. Exacerbation rates (0.07-0.27 per patient per year) and improvement in health status were significantly better with salmeterol/fluticasone. This study confirms that the goal of guideline-derived asthma control was achieved in a majority of the patients.

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 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.

Exacerbations of chronic obstructive pulmonary disease (COPD) greatly contribute to declining health status and the progression of the disease, thereby incurring significant direct and indirect health care costs. The prevention of exacerbations, therefore, is an important treatment goal. To assess the impact of combination therapy with salmeterol/fluticasone propionate compared with salmeterol alone on moderate and severe exacerbations in patients with severe COPD and a history of repeated exacerbations. Randomized, double-blind, parallel-group study. After a 4-wk run-in period, 994 clinically stable patients were randomized to one of two treatment groups: 507 patients received the salmeterol/fluticasone combination 50/500 micro g twice daily and 487 received salmeterol 50 micro g twice daily for 44 wk. The total number of exacerbations was 334 in the combination therapy and 464 in the salmeterol group (p < 0.0001). The annualized rate of moderate and severe exacerbations per patient was 0.92 in the combination therapy and 1.4 in the salmeterol group, corresponding to a 35% decrease. In addition, the mean time to first exacerbation in the combination therapy group was significantly longer compared with that of the salmeterol group (128 vs. 93 d, p < 0.0001). Other endpoints, including health-related quality of life, peak expiratory flow, and use of rescue medication, were significantly improved in the combination therapy group. Both treatments were well tolerated. This study demonstrates that combination therapy with salmeterol/fluticasone compared with salmeterol monotherapy significantly reduces the frequency of moderate/severe exacerbations in patients with severe COPD.

This trial involving more than 6000 patients with chronic obstructive pulmonary disease (COPD) compared the effects on all-cause mortality of treatment with an inhaler containing both salmeterol and fluticasone, salmeterol or fluticasone alone, or placebo. After 3 years, the study showed a reduction of 2.6 percentage points in the mortality rate; this fell short of the study's prespecified goals. There were improved clinical outcomes among patients treated with the combination regimen.

After 3 years, the study showed a reduction of 2.6 percentage points in the mortality rate, which fell short of the prespecified goal. Chronic obstructive pulmonary disease (COPD) is a major cause of illness, death, and the use of health care resources globally. 1 – 3 The disease causes approximately 2.75 million deaths annually, and the number is projected to increase. 2 Treatment for COPD is focused on minimizing risk factors, improving symptoms, and preventing exacerbations. 3 With the exception of smoking-cessation programs for patients with early disease, 4 home oxygen treatment for persistent hypoxemia, 5 , 6 and lung-reduction surgery for selected patients with emphysema, 7 no treatment has been shown to reduce mortality. Pulmonary inflammation is prominent in COPD. 8 Antiinflammatory drugs such as inhaled corticosteroids have little or no . . .

Combination inhaled corticosteroid–formoterol reliever monotherapy reduces the rate of asthma attacks compared to short-acting β2-agonist (SABA) reliever monotherapy in adults. Its comparative efficacy in children has not been established. CARE was a 52-week, open-label, parallel-group, multicentre, superiority, randomised controlled trial in children aged 5–15 years with asthma using SABA reliever monotherapy at 15 clinical trials sites in New Zealand. Participants were randomly assigned (1:1) to either budesonide 50 μg–formoterol 3 μg, two actuations as needed, or salbutamol 100 μg, two actuations as needed. The primary outcome was asthma attacks as rate per participant per year. This trial was registered with the Australian New Zealand Clinical Trials Registry, ACTRN12620001091998. From Jan 28, 2021, to June 23, 2023, we assessed 382 participants for eligibility. We randomly assigned 360 (94%) participants to treatment (179 [50%] to the budesonide–formoterol group and 181 [50%] to the salbutamol group). The annualised rate of asthma attacks was lower in the budesonide–formoterol group than in the salbutamol group—cluster-adjusted rates 0·23 versus 0·41 per participant per year (relative rate 0·55 [95% CI 0·35–0·86]; p=0·012). The number of participants with at least one adverse event was 162 (91%) in the budesonide–formoterol group and 167 (92%) in the salbutamol group (odds ratio 0·79 [95% CI 0·35–1·79]). In children aged 5–15 years with mild asthma, budesonide–formoterol reliever monotherapy is superior to salbutamol for preventing asthma attacks, with a similar safety profile.

Exacerbations are key drivers of morbidity and mortality in chronic obstructive pulmonary disease (COPD). We compared the relative efficacy of the long-acting inhaled bronchodilator/antiinflammatory combination (salmeterol/fluticasone propionate) 50/500 microg twice daily and the long-acting bronchodilator (tiotropium) 18 microg once daily in preventing exacerbations and related outcomes in severe and very severe COPD. A total of 1,323 patients (mean age, 64 yr, post-bronchodilator FEV1, 39% predicted) were randomized in this 2-year, double-blind, double-dummy parallel study. Primary endpoint was health care utilization exacerbation rate. Other endpoints included health status measured by St. George's Respiratory Questionnaire (SGRQ), mortality, adverse events, and study withdrawal. Probability of withdrawing from the study was 29% greater with tiotropium than salmeterol/fluticasone propionate (P = 0.005). The modeled annual exacerbation rate was 1.28 in the salmeterol/fluticasone propionate group and 1.32 in the tiotropium group (rate ratio, 0.967; 95% confidence interval [CI], 0.836-1.119]; P = 0.656). The SGRQ total score was statistically significantly lower at 2 years on salmeterol/fluticasone propionate versus tiotropium (difference 2.1 units; 95% CI, 0.1-4.0; P = 0.038). Mortality was significantly lower in the salmeterol/fluticasone propionate group; 21 (3%) of patients in this group died compared with 38 (6%) in the tiotropium group (P = 0.032). More pneumonias were reported in the salmeterol/fluticasone propionate group relative to tiotropium (P = 0.008). We found no difference in exacerbation rate between salmeterol/fluticasone propionate and tiotropium. More patients failed to complete the study while receiving tiotropium. A small statistically significant beneficial effect was found on health status, with an unexpected finding of lower deaths in salmeterol/fluticasone propionate-treated patients. Clinical trial registered with www.clinicaltrials.gov (NCT 00361959).

To compare the safety of salmeterol xinafoate or placebo added to usual asthma care. A 28-week, randomized, double-blind, placebo-controlled, observational study. Study subjects were seen once in the study physician's office for screening and were provided all blinded study medication for the entire study period. Follow-up by telephone was scheduled every 4 weeks. Subjects (> 12 years old) with asthma as judged by the study physician were eligible. Individuals with a history of long-acting beta2-agonist use were excluded. Salmeterol, 42 mug bid via metered-dose inhaler (MDI), and placebo bid via MDI. Following an interim analysis in 26,355 subjects, the study was terminated due to findings in African Americans and difficulties in enrollment. The occurrence of the primary outcome, respiratory-related deaths, or life-threatening experiences was low and not significantly different for salmeterol vs placebo (50 vs 36; relative risk [RR] = 1.40; 95% confidence interval [CI], 0.91 to 2.14). There was a small, significant increase in respiratory-related deaths (24 vs 11; RR, 2.16; 95% CI, 1.06 to 4.41) and asthma-related deaths (13 vs 3; RR, 4.37; 95% CI, 1.25 to 15.34), and in combined asthma-related deaths or life-threatening experiences (37 vs 22; RR, 1.71; 95% CI, 1.01 to 2.89) in subjects receiving salmeterol vs placebo. The imbalance occurred largely in the African-American subpopulation: respiratory-related deaths or life-threatening experiences (20 vs 5; RR, 4.10; 95% CI, 1.54 to 10.90) and combined asthma-related deaths or life-threatening experiences (19 vs 4; RR, 4.92; 95% CI, 1.68 to 14.45) in subjects receiving salmeterol vs placebo. For the primary end point in the total population, there were no significant differences between treatments. There were small, but statistically significant increases in respiratory-related and asthma-related deaths and combined asthma-related deaths or life-threatening experiences in the total population receiving salmeterol. Subgroup analyses suggest the risk may be greater in African Americans compared with Caucasian subjects. Whether this risk is due to factors including but not limited to a physiologic treatment effect, genetic factors, or patient behaviors leading to poor outcomes remains unknown.

In patients with severe COPD receiving inhaled glucocorticoids and two classes of long-acting bronchodilators, glucocorticoid withdrawal was noninferior to continuation with respect to exacerbations but was associated with a slight worsening in lung function and symptoms. Exacerbations of chronic obstructive pulmonary disease (COPD) are symptomatically defined, acute events that lead to a change in treatment 1 , 2 and are associated with an accelerated decline in lung function and health status. 3 Treatment with inhaled glucocorticoids reduces the exacerbation rate, especially when the drugs are used in combination with a long-acting β-agonist (LABA). 4 , 5 Consequently, combination therapy with an inhaled glucocorticoid and a LABA is recommended in patients with severe COPD or a history of frequent exacerbations. 2 Long-acting muscarinic antagonists (LAMAs) have also been shown to prevent exacerbations. 6 – 8 However, in patients with severe or very severe COPD and . . .
