Best way to use three lung medications for COPD

This trial is testing whether Trimbow — a single inhaler containing three medications — helps people with COPD take their medicine more consistently compared to using multiple separate inhalers. The study also checks whether adding a digital app to help remind you to use your medication makes a real difference. Researchers want to understand which approach makes it easiest for you to stick with your treatment.

Many people with COPD struggle to use their inhalers regularly because managing multiple devices is confusing and hard to remember. This trial aims to find out whether simplifying treatment with a single inhaler, possibly combined with digital reminders, helps people use their medications as prescribed.
