From what I recall, there was a big price increase for asthma inhalers when they switched from CFCs to other propellants. That being said, I thought the new propellants were going to go generic after a few years.
Has that not happened yet? Or did people / insurance companies adapt to the higher prices so that the new generics can charge more than the old ones?
I don't think albuterol is available in that form. Here's a study where a company that makes generics is testing that, I think: https://clinicaltrials.gov/ct2/show/NCT01857323. It's from 2013.
The drugs in Diskus form are typically steroids. Steroids are to prevent attacks, albuterol is to stop attacks that have already started.
