About
The aim of this study was to compare the efficacy and tolerability of the fixed combination beclomethasone/formoterol pMDI with that of budesonide/formoterol dry powder via Turbuhaler.
Full description
Asthma is a chronic disease that is estimated to affect over 25 million people both in the U.S. and in Europe (i.e. approximately 10% of the total population). Pharmacological therapy is used to treat reversible airway obstruction, inflammation and hyper-reactivity. Medications include preventive treatments in forms of antinflammatory/antiallergic agents (i.e. glucocorticosteroids, leukotriene antagonists, cromolyn sodium) and reliever treatments, in forms of bronchodilators (i.e. β-adrenergic agonists, anticholinergics). In patients treated with inhaled glucocorticosteroids whose asthma is not fully controlled, national and international guidelines recommend a stepwise approach. Recent evidence-based clinical trials show that the addition of a LABA to inhaled glucocorticosteroids is more beneficial in terms of asthma control than increasing the dose of corticosteroids alone.
COMPARISONS: CHF 1535 (BECLOMETHASONE DIPROPIONATE 100 µg+ FORMOTEROL 6 µg) pMDI via HFA-134a compared to SYMBICORT (BUDESONIDE 160 µg + FORMOTEROL 4,5 µg).

Inclusion criteria
Clinical diagnosis of moderate to severe persistent asthma for at least 6 months, according to GINA revised version 2002 guidelines:
Forced expiratory volume (FEV1) or peak expiratory flow rate (PEFR) > 50% and < 80% of the predicted normal;
Asthma not adequately controlled with the current therapies, defined as presence of daily asthma symptoms > once a week and night-time asthma symptoms > twice a month, and daily use of short-acting β2-agonists. These findings are to be based on recent medical history and are to be confirmed in the 2-week run-in period.
