In the present study, we examined whether there is a difference in the onset of bronchodilatation between formoterol/beclomethasone 12/200 μg Modulite and formoterol/budesonide 9/320 μg Turbuhaler in patients with COPD. We enrolled 28 patients with stable COPD. Both formoterol/beclomethasone and formoterol/budesonide elicited a larger mean FEV₁-AUC₀₋₁₅min than formoterol alone, whereas there wa...

BACKGROUND The contributions of as-needed inhaled corticosteroids and long-acting beta2 agonists (LABA) to asthma control have not been fully established. We compared the efficacy and safety of three reliever strategies: a traditional short-acting beta2 agonist; a rapid-onset LABA (formoterol); and a combination of LABA and an inhaled corticosteroid (budesonide-formoterol) in symptomatic patien...

OBJECTIVE To assess efficacy/tolerability of once-daily budesonide/formoterol pressurized metered-dose inhaler (pMDI) versus budesonide pMDI (primary) and twice-daily budesonide/formoterol (secondary) in children/adolescents with asthma stabilized with twice-daily budesonide/formoterol. METHODS This 12-week multicenter, double-blind randomized controlled study (www.clinicaltrials.gov identifi...

This randomised, double-blind, 6-month study compared budesonide/formoterol for maintenance and relief with salmeterol/fluticasone and a fixed maintenance dose of budesonide/formoterol, both with terbutaline for relief. Following a 2-week run-in, 3335 symptomatic adults and adolescents (mean FEV1 73% predicted, mean inhaled corticosteroid dose 745 microg/day) received budesonide/formoterol 160/...

BACKGROUND Increased pulmonary arterial vascular smooth muscle (PAVSM) cell proliferation is a key pathophysiological component of pulmonary vascular remodeling in pulmonary arterial hypertension (PH). The long-acting β2-adrenergic receptor (β2AR) agonist formoterol, a racemate comprised of (R,R)- and (S,S)-enantiomers, is commonly used as a vasodilator in chronic obstructive pulmonary disease ...

BACKGROUND The combination of an inhaled corticosteroid (ICS) and a long-acting bronchodilator is recommended in the treatment of patients with chronic obstructive pulmonary disease (COPD) who have frequent exacerbations. Budesonide/formoterol dry powder inhaler (DPI) has demonstrated efficacy and tolerability in patients with COPD. OBJECTIVE To evaluate the efficacy and tolerability of budes...

The safety of long-acting beta(2)-agonist (LABA) treatment in asthma has been questioned following reported increased respiratory deaths when salmeterol was added to usual pharmacotherapy. The aim of this study was to examine whether asthma, cardiac or all-cause mortality and morbidity were increased with formoterol use. The analysis included all AstraZeneca randomised controlled parallel-group...

OBJECTIVES The inhaled corticosteroid fluticasone propionate (fluticasone) and the long-acting β₂ agonist formoterol fumarate (formoterol) have been combined in a single aerosol inhaler fluticasone/formoterol (flutiform(®)). This study compared the efficacy and safety of fluticasone/formoterol with the combination product budesonide/formoterol (Symbicort(®) Turbohaler(®)). METHODS A randomize...

Mechanisms underlying β2-adrenoreceptor (β2AR) inverse agonist mediated bronchoprotectiveness remain unknown. We incubated ICI118,551, formoterol, budesonide, and formoterol plus budesonide, as well as ICI118,551 or pindolol plus formoterol, ICI118,551 plus forskolin, SQ22,536 or H89 plus formoterol in ASMCs to detect expressions of M3R, PLCβ1 and IP3. The level of M3R in the presence of 10-5 m...

The efficacy and safety of budesonide/formoterol in a single inhaler compared with placebo, budesonide and formoterol were evaluated in patients with moderate-to-severe chronic obstructive pulmonary disease (COPD). In a 12-month, randomised, double-blind, placebo-controlled, parallel-group study in 812 adults (mean age 64 yrs, mean forced expiratory volume in one second (FEV1) 36% predicted nor...
