Head-to-head evidence
albuterol HFA (Armstrong's) vs Proventil
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.

albuterol HFA (Armstrong's)
Marketed by Amphastar Pharmaceuticals, Inc.
NCT00635505 · Phase 3 · terminated
This is a randomized, quadruple-blind, placebo- and active-controlled study with an adequate sample size measuring lung function directly, but no results have been posted yet, so the outcome is unknown.
Proventil
Marketed by Amphastar Pharmaceuticals, Inc.
NCT00577655 · Phase 3 · completed
The trial randomized 103 children to albuterol or placebo and masked participants, caregivers, investigators, and outcome assessors. Its primary measures were physiologic lung-function outcomes rather than hard clinical outcomes; the FEV1 comparison was statistically significant, while the PEF comparison was not significant at the prespecified threshold, so the findings were mixed.
