AIM To evaluate the efficacy and tolerability of formoterol delivered by Aerolizer in the emergency department. METHODS A single-centre, double-blind, randomised, placebo-controlled, parallel group study was conducted in patients seeking emergent care for an acute exacerbation of asthma. Patients were randomly assigned to one of two groups: group 1 (salbutamol), receiving a total dose of 600 ...

OBJECTIVE Immunophilin FKBP51 assists polypeptide folding, participates in glucocorticoid actions and may play a role in glucocorticoid resistance. FKBP51 is altered in patients with asthma, but its role in chronic obstructive pulmonary disease (COPD) characterized by dysregulation of several pro/antiinflammatory genes is less clear. METHODS We assessed changes in nuclear/cytosolic FKBP51 pro...

This study compared the bronchodilator effects of tiotropium, formoterol and both combined in chronic obstructive pulmonary disease (COPD). A total of 71 COPD patients (mean forced expiratory volume in one second (FEV1) 37% predicted) participated in a randomised, double-blind, three-way, crossover study and received tiotropium 18 microg q.d., formoterol 12 microg b.i.d. or both combined q.d. f...

BACKGROUND The combination of short-acting beta(2)-agonists and anticholinergics in the treatment of COPD has been well documented, but data on combination of long-acting agents are lacking. METHODS A randomized, open-label, placebo-controlled, three-way crossover study was conducted comparing 2-week treatment periods of tiotropium alone to tiotropium plus formoterol once or twice daily follo...

Salmeterol and formoterol are two long-acting beta2-agonists for inhalation, currently being used in clinical practice. The aim of the present study was to investigate the onset of action, duration of effect and potency of these two beta2-agonists in asthmatic patients. Patients (n=28) were included on the basis of salbutamol stepwise reversibility (100, 100 and 200 microg, given cumulatively; ...

The budesonide-formoterol dry powder inhaler (Symbicort Turbuhaler 160/ 4.5-640/18 microg/day) contains the long-acting beta2-adrenoreceptor agonist formoterol and the inhaled corticosteroid budesonide. Two large, 12-month trials examined the effect of budesonide-formoterol 160/4.5 microg twice daily in COPD patients who met these criteria. The studies were identical, except one in which the pa...

BACKGROUND The inhaled corticosteroid (ICS) fluticasone propionate (fluticasone) and the long-acting β2-agonist (LABA) formoterol fumarate (formoterol) are being made available as a combination product (fluticasone/formoterol, flutiform ®) in a single aerosol inhaler. This 12-week, open-label, randomized, active-controlled, parallel-group, multicentre, phase 3 study compared the efficacy and sa...

OBJECTIVE Arformoterol is the (R,R)-enantiomer of formoterol. Preclinical studies suggest that it is a stronger bronchodilator than the racemic (R,R/S,S)-formoterol; however, its potential clinical advantages have not been demonstrated. This study compared the length of stay (LOS), 30-day readmission rates, and doses of rescue medication administered in hospitalized patients with COPD who were ...

BACKGROUND Budesonide/formoterol is an effective treatment for both asthma and chronic obstructive pulmonary disease. This study compared the efficacy and safety of a novel hydrofluoroalkane (HFA) pressurised metered-dose inhaler (pMDI) formulation of budesonide/formoterol with that of budesonide pMDI and budesonide/formoterol dry-powder inhaler (DPI; Turbuhaler). METHODS This was a 12-week, ...

BACKGROUND Oral corticosteroids and inhaled bronchodilators with or without antibiotics represent standard treatment of COPD exacerbations of moderate severity. Frequent courses of oral steroids may be a safety issue. We wanted to evaluate in an out-patient setting whether a 2-week course of inhaled budesonide/formoterol would be equally effective for treatment of acute COPD exacerbations as st...
