"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 agree. I have been using asthma inhalers for years and I see no difference in effectiveness. I must say that the current inhaler I use has a better aftertaste than the old ones. I don’t know if that has to do with this or not. They cost the same for me and work just as well.

For years, I wasn’t using my inhaler properly. Most people I see using them use them incorrectly. I still use a spacer just to insure that I get the most from my medication.
