Randomized Controlled Trial Multicenter Study Comparative StudyComparison of adjustable- and fixed-dose budesonide/formoterol pressurized metered-dose inhaler and fixed-dose fluticasone propionate/salmeterol dry powder inhaler in asthma patients.
The adjustable-dose budesonide/formoterol dry powder inhaler (DPI) has demonstrated similar or greater asthma control with less inhaled corticosteroid compared with the fixed-dose budesonide/formoterol DPI. ⋯ Adjustable-dose and fixed-dose budesonide/formoterol showed no differences in asthma control or tolerability versus fixed-dose fluticasone propionate/salmeterol.
