This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether a new albuterol sulfate inhaler works just as well as the brand-name ProAir HFA inhaler. Both inhalers contain the same active ingredient and deliver the same dose per puff. The study measures how effectively each inhaler opens the airways in people with mild asthma by using a special breathing test called a methacholine challenge.
Generic and brand-name inhalers are supposed to work the same way, but this study is checking that the new version truly performs equally to the established one. This helps ensure patients can safely use either version without any difference in how well it controls their asthma.

You will visit the study center multiple times to test different inhalers in a crossover design, meaning you will try several different versions (some active, some placebo) on separate occasions. Before and after using each inhaler, you will breathe in increasing amounts of methacholine—a substance that temporarily tightens airways—and perform breathing tests to measure how well the inhaler protected your airways. The study involves careful monitoring to ensure your safety throughout the process.
