Head-to-head evidence
fenoterol vs Ventolin
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.
Asthma
Shared mechanism: Beta-2 adrenergic receptor · full Asthma pipeline
fenoterol
Developed by Boehringer Ingelheim
NCT02177370 · Phase 3 · terminated
This was a randomized, double-blind, active-controlled crossover study, but it enrolled only 19 participants and one of its two primary measures is a laboratory receptor-density biomarker rather than a direct asthma outcome, and no results have been posted.
Ventolin
Developed by GlaxoSmithKline
NCT01076322 · Phase 3 · completed
The study randomized participants to treatment sequences and included Ventolin as the active comparator, but it was open-label and small, with an estimated 17 participants. Its primary endpoint, change in FEV1, is a clinical lung-function measure, but no results are posted to show whether the comparison was favorable for Ventolin or met its prespecified objective.
