BACKGROUND International guidelines recommend the use of systemic steroids for the treatment of acute asthma attack if it has not been resolved within 24 to 36 hours of home management with regular beta2 mimetic inhalation. Such therapy for infrequent exacerbations is unlikely to have serious systemic effects. Unfortunately, many patients receiving frequent courses are potentially at risk for c...

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...

Inhaled corticosteroids form the mainstay of the treatment and management of asthma and the results of a meta-analysis comparing two of the most frequently prescribed inhaled corticosteroids, fluticasone propionate and budesonide, administered in a clinically equivalent 1:2 dose ratio to 1980 patients with asthma, demonstrated that fluticasone propionate had an improved efficacy:safety ratio. H...

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 (FEV1) 36% predicted) initially received formoterol (9 microg b.i.d.) and oral prednisolone...

BACKGROUND High doses of inhaled corticosteroids are absorbed systemically and may cause long term side effects. As rinsing the mouth out after use and inhaling through a spacing device may reduce systemic absorption this has been further investigated. METHODS Three crossover studies were carried out to assess the effect of budesonide given by dry powder inhaler (Turbuhaler) with and without ...

Although some studies suggest that asthma deteriorates after reducing inhaled steroids, results of long-term studies indicate that this might not be true for all patients. The aim of this study was to determine the utility of the detection of a plateau on the concentration-response curves to inhaled methacholine as a marker for safely reducing the dose of inhaled budesonide in asthmatic patient...

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 ...

This study was performed to determine the effects of high doses of two inhaled corticosteroids, beclomethasone dipropionate and budesonide, on biochemical indices of bone turnover (urinary hydroxyproline:creatine and calcium:creatinine ratios, plasma alkaline phosphatase, and parathyroid hormone). Twelve healthy male doctors, aged 25-36 (mean 30) years, were studied. After a week's run in perio...

A double blind, parallel group study was carried out to investigate the effect of inhaled budesonide in a moderate (200 micrograms) and a low (100 micrograms) twice daily dosage compared with the effect of placebo in 103 adults with mild symptomatic asthma. Subjects recorded peak expiratory flow (PEF), asthma symptoms, and beta 2 agonist consumption at home for a period of seven weeks (a one we...
