Head-to-head evidence
albuterol / budesonide vs fluticasone propionate/salmeterol
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

NCT03769090 · Phase 3 · completed
Participants were randomized and quadruple-blinded across two budesonide/albuterol groups and an active albuterol comparator, with 3,132 randomized participants. The primary clinical endpoint was met for both doses: severe exacerbations occurred in 207/1,013 versus 266/1,014 participants for high-dose treatment (hazard ratio 0.733, p<0.001) and 241/1,054 versus 276/1,056 for low-dose treatment (hazard ratio 0.835, p=0.041).

fluticasone propionate/salmeterol
Developed by GlaxoSmithKline
NCT00920959 · Phase 3 · completed
The trial randomized 908 participants to combination therapy, fluticasone propionate, or placebo under double-blind conditions. Its primary endpoint was change in daily evening peak expiratory flow after 12 weeks, a pulmonary-function surrogate, and the registry does not report whether this endpoint was met.
