New hope for stubborn CF lung damage: study tests extra Mucus-Busting therapy

This study looked at whether adding an inhaled powder called Bronchitol could help clear sticky mucus from the lungs of adults with moderate-to-severe cystic fibrosis who were already taking a highly effective triple-drug therapy (E/T/I). Researchers wanted to see if the extra treatment could further improve the lungs' natural cleaning process, potentially helping patients who still have significant lung damage despite modern medication. The study measured how quickly tiny tracer particles were cleared from the lungs over 60 and 90 minutes.
