- Flovent HFA
- Azmanex Twisthaler
Another neat thing to mention is that the HFA propellant appears to be finer than the CFC propellant, which means the inhaled corticosteroids may get deeper into the lungs to provide better distribution of the medicine. This has been proven by some studies. Some hardluck asthmatics have been experimenting taking a few puffs a day of Qvar to go along with their Advair, or Symbicort, or Dulera.
I believe at the present time there will soon be another inhaled steroid on the market, and I think there are already attempts being made to have it released in a combination inhaler with fluticasone (Flovent). Fluticasone is presently combined with Salmeterol (Sevevent) in Advair.
