How LuciBren Works
In bronchiectasis, the lungs are often caught in a cycle of ongoing inflammation and damage, even when the body is trying to fight infection. Over time, this can lead to more mucus, frequent flare-ups, and difficulty breathing.
LuciBren helps break this cycle by calming the overactive processes inside the lungs. It reduces the activity of substances that cause inflammation, helping to protect lung tissue and prevent further damage.
Specifically, Brensocatib works by inhibiting an enzyme called DPP-1 (dipeptidyl peptidase-1), which plays a key role in activating inflammatory cells.
With continued use, this can lead to fewer flare-ups, better breathing, and improved overall lung health.
