@JaniceD, hi Jan! thank you for the updated information I was positive it was still current! fascinating story with funding - but I suppose the truth can be stranger than fiction.
I don’t know the origin however, I know a lot about medicines sold in the united stated with active FDA licenses: if it is available through a US pharmacy then the factory where it was made was licensed to make it and sell it so, the company showed the quality necessary to maintain that license, and was under the supervision and inspection of the FDA. nothing is perfect but that is potentially safer than buying from a unlicensed source.
no I only knew Afrezza was on the market because the original (Exubera) interested me… the company I was working for at the time was trying to make an insulin “patch” (transdermal insulin) and the inhaled version would have kicked it’s behind. Transdermal never worked anyway but Exubera did get approved and subsequently failed. Then Afrezza was in clinicals and people shared that it did actually work - I was happy for an alternate but I lost interest and stopped following it.
Pharma, as a investment, has been flat for a long time. With the new biological medicines, there has been some growth, but my guess is you are better off with index funds
good luck Jan!
