Pfizer tried for awhile and then gave it up. Generex is not making an inhaled insulin. Ora-lyn is a mist spray which is absorbed into the buccal tissue inside the mouth, it does not enter the lungs.
Generex had an appetite suppressant product on the market for awhile for people who were trying to diet. It worked the same way. I bought a package just for the heck of it and tried it. It seemed to work okay and it was not inhaled either.
