Does the new propellant get that dose to the lungs or is a larger amount wasted in the mouth and throat because it doesn't get dispersed well enough?
Exact same amount of pressure in the inhaler as before.
The only problem with inhalers is most people don't know how to use them properly. They should use a Aero chamber until they learn how to inhale properly when using the medication.
I was sucked in to all they hype until I actually used the new stuff, and realized that it is no different at all that the old CFC propellant stuff, which is probably more dangerous even in the minute amounts they claim is used.
I have reduced lung function due to scarring caused by scleroderma.
