Inhaler propellant test: does new formula clear lungs better?
NCT ID NCT05755932
Summary
This study tested whether a new, more environmentally friendly inhaler propellant (HFO) works as well as the current standard (HFA) at helping clear mucus from healthy lungs. Thirty-five healthy, non-smoking adults used both types of inhalers for one week each. Researchers used a special imaging scan to measure how quickly a harmless tracer was cleared from participants' airways to compare the two propellants.
