Inhaler propellant showdown: does the new one keep lungs as clean?

NCT ID NCT06506266

First seen Apr 20, 2026 · Last updated May 16, 2026 · Updated 6 times

Summary

This study tested whether a new inhaler propellant (HFA-152a) affects the lungs' ability to clear mucus compared to a standard propellant (HFA-134a). Twenty-four healthy adults inhaled each propellant for a week, and researchers measured mucus clearance using a radioactive tracer. The goal was to check safety and lung function, not to treat any disease.
