ABSTRACT: Budesonide/formoterol in one inhaler is an established therapy for asthma and chronic obstructive pulmonary disease. The long-term safety and efficacy profile of a novel hydrofluoroalkane (HFA) pressurized metered-dose inhaler (pMDI) formulation of budesonide/formoterol was compared with that of budesonide/formoterol in a dry powder inhaler (DPI; Turbuhaler). This multinational, 52-week, randomized, open, parallel-group study included patients aged > or = 12 years with asthma who had a forced expiratory volume in 1s (FEV1)> or = 50% of predicted normal; all patients used inhaled corticosteroids (400-1200 microg/day) and needed additional short-acting beta 2-agonist therapy. Patients were randomized to receive budesonide/formoterol pMDI or DPI 160/4.5 microg, two inhalations twice daily. Safety endpoints included assessment of adverse events and laboratory parameters. Efficacy endpoints included change from baseline in FEV1 and time to first severe asthma exacerbation. Overall, 673 patients (446pMDI, 227DPI) were included. There were no clinically significant differences between treatment groups in the nature, incidence or severity of adverse events or laboratory parameters. The number of patients experiencing adverse events was comparable in the pMDI (332/446 [74%]) and DPI (175/227 [77%]) groups; the most commonly reported adverse event was upper respiratory tract infection. The proportion of patients discontinuing as a result of adverse events was low in both groups (pMDI 12/446 [3%], DPI 2/227 [1%]). Lung function was improved to a similar extent in both groups and there was no detectable difference in time to first severe asthma exacerbation. The novel HFA pMDI formulation of budesonide/formoterol is an equally well tolerated and effective treatment for adults and adolescents with asthma as the budesonide/formoterol DPI.Pulmonary Pharmacology & Therapeutics 01/2008; 21(1):32-9. · 2.80 Impact Factor -
Article: Effects of esomeprazole 40 mg twice daily on asthma: a randomized placebo-controlled trial.

ABSTRACT: Gastroesophageal reflux disease (GERD) is common in patients with asthma, suggesting an interaction between the two conditions. To assess the effect of gastric acid suppression with the proton pump inhibitor esomeprazole on asthma outcomes in subjects with persistent moderate to severe asthma treated with antiinflammatory asthma medication. In this double-blind study, subjects were randomized to receive esomeprazole 40 mg or placebo twice daily for 16 wk. According to nocturnal respiratory symptoms (NOC) and GERD, subjects were divided into three strata: GERD-/NOC+, GERD+/NOC-, and GERD+/NOC+. A total of 770 subjects were randomized. There was no statistically significant improvement in morning peak expiratory flow (PEF) over placebo in the overall study population: 6.3 L/min (p = 0.061). Over the whole treatment period, in GERD+/NOC+ subjects (n = 350), esomeprazole provided an 8.7-L/min improvement (p = 0.03) in morning PEF, and a 10.2-L/min improvement (p = 0.012) in evening PEF over placebo. Among 307 subjects taking long-acting beta2-agonists, improvements over placebo were observed in morning PEF (12.2 L/min, p = 0.017) and in evening PEF (11.1 L/min, p = 0.024); these improvements were more pronounced in GERD+/NOC+ subjects. Esomeprazole 40 mg twice daily was well tolerated and no safety concerns were noted. Esomeprazole improved PEF in subjects with asthma who presented with both GERD and NOC. In subjects without both GERD and NOC, no improvement could be detected.American Journal of Respiratory and Critical Care Medicine 06/2006; 173(10):1091-7. · 11.08 Impact Factor
