Abstract

Context:The combination of inhaled corticosteroids (ICS) and long-acting beta-agonists (LABA) is widely used in the treatment of moderate-to-severe asthma uncontrolled by ICS alone.Aims:To evaluate the efficacy and safety of a new ICS-LABA combination inhaler containing Formoterol (F) and Ciclesonide (C).Settings and Design:A double-blind, double-dummy, parallel group fashion, multi-centric study.Subjects and Methods:A total of 169 asthma patients received Ciclesonide 80 μg once daily during a 4-week run-in period, after which, they were randomized to receive either C (80 μg) or a combination of F (4.5 μg) and C (80 μg) (FC) both delivered through a hydro-fluro-alkane pressurized-metered-dose inhaler as 1 puff twice daily, for 6 weeks.Statistical Analysis Used:Inter-group differences were compared using t-test for independent samples at a significance level of 5%.Results:From baseline, the improvements in forced expiratory volume in 1 s at 1, 3, and 6 weeks was significantly higher in the FC group compared to Group C (110 ml vs. 40 ml, 140 ml vs. 20 ml, and 110 ml vs. 40 ml, respectively, all P < 0.05). From baseline, the improvements in mean morning peak expiratory flow at 1, 3, and 6 weeks was significantly higher in the FC group compared to Group C (17 L/min vs.−3 L/min, 22 L/min vs. 3 L/min, and 30 ml vs. 8 L/min respectively, all P < 0.05). The changes in symptom scores were similar in both the groups. The adverse events in the FC group were not significantly different from those in the C group.Conclusions:FC provides better improvement than C alone in terms of lung function and symptoms without increased risk of adverse events in asthma patients.
