Unfortunately, according to the study
At this point, everyone grabs for their reliever medication, the muscles around the airways relax and the
inflammation is reduced, but the mucus is still stuck in the airways, because this mucus has special
properties which make it harder to clear.
“For over 100 years, pathologists have recognized the primary role diffuse
mucus plugging play in the pathophysiology of asthma. However, many
clinicians do not recognize and treat mucus dysfunction in patients with
asthma, possibly because cough in asthma is often unproductive and therapies
for asthma focus mainly on reversing bronchoconstriction and inflammation,
thereby resulting in unavailability of therapies to clear mucus plugs in asthma.”
