Breztri is a triple therapy: a LAMA, a LABA and a steroid. Two bronchodilators working on different targets in the lungs with a steroid to reduce inflammation. We all respond differently to the various chemicals used in the meds from different pharma companies, so how well he does will depend on how well he responds to the chemicals used in Breztri. Everyone's different and he may respond really well or it may not make much difference from his current medication. If Breztri doesn't work well for him, he can try Trelegy, which is also a triple therapy, but uses different chemicals. It's possible that neither will work very well. He'll have to decide for himself how things work for him.

I'm using breztri to me they all work the same which is not very good

My specialist changed my meds from bro and encruise to Brett via aero chamber. I feel I get the full dose using the aero chamber and feel immediate relief after taking it.
This was after a flare-up which has generally made shortness of breath more frequent with activity.
I need rescue inhalers ventolin and atrovent as well. I space my meds out every 4 hours.

Re breztri and propellant issue. I use a spacer and it is a Godsend . It delivers breztri much more effectively. Got one from my pulmonologist.

Steroids even corticosteroids mess with us! Some more than others. I’ve noticed my white cells are slays high when on prednisone as well as my sugars! I’m glad to be off them.
