Head-to-head evidence
albuterol / budesonide vs Albuterol sulfate (Armstrong)
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).
Next expected readout: February 2027 · NCT06422689 (registry estimate)
Albuterol sulfate (Armstrong)
Marketed by Amphastar Pharmaceuticals, Inc.
NCT00634517 · Phase 3 · terminated
This is a randomized, quadruple-blind, active-controlled study directly measuring lung function, but the sample size is small for a pediatric population and no results have been posted yet, so the outcome is unknown.
Next expected readout: April 2028 · NCT07426458 (registry estimate)
