Introduction: In the prospective, observational, 16-week REACT study conducted between October 21, 2008 and May 12, 2011, we compared the real-world effectiveness of anti-inflammatory reliever and maintenance therapy with budesonide/formoterol (Symbicort® Turbuhaler) and maintenance therapy with fixed-dose fluticasone/salmeterol (Seretide®) plus as-needed, short-acting β 2 agonists (SABAs) in Taiwanese patients with inadequate asthma control.
Methods: Asthma control was assessed using the five-item Asthma Control Questionnaire (ACQ-5) and standardized pulmonary function testing. Assessments were performed at baseline and at weeks 4– 5 and 12– 16. Overall, we enrolled 842 patients at 11 clinics, 723 of whom were included in analyses (budesonide/formoterol, 563.3± 1.3 μg/d, n=551; fluticasone/salmeterol, 1013.8± 1.4 μg/d, n=172).
Results: At baseline, 72.5% and 27.5% of all patients had “partly” and “uncontrolled” asthma, respectively. Mean±SD ACQ-5 scores were 1.54± 1.06 and 1.46± 1.28 in the budesonide/formoterol and fluticasone/salmeterol groups, respectively. ACQ-5 scores significantly improved from baseline (ie, decreased) in both groups at weeks 4 and 16. ACQ-5 difference scores were significantly lower in the budesonide/formoterol group (− 0.91± 1.11) than the fluticasone/salmeterol group (− 0.69± 1.27) at the end of the study (p=0.027). Peak expiratory flow rate significantly improved from baseline in the budesonide/formoterol but not the fluticasone/salmeterol group at the end of the study. Severe exacerbation rates and medical resource utilization were comparable between the budesonide/formoterol and fluticasone/salmeterol groups.
Conclusion: Collectively, results indicate the real-world effectiveness of budesonide/formoterol anti-inflammatory reliever and maintenance therapy is better than fixed-dose fluticasone/salmeterol plus as-needed SABA.
Trial Registration: registration number: NCT00784953.
