Inhaled GLP-1s sound too good to be true

This article is about Aptar Pharma working on ways to deliver GLP-1s through nasal sprays or inhalers instead of shots. They are currently in the preclinical stage with new patents.
I am skeptical about this. I hate needles, but I also hate the idea of spraying this stuff up my nose. It seems overhyped right now since it is so early in the process. Most of these "breakthroughs" never actually make it to the public, or they end up being less effective than the original version.
If the absorption rate is low, it is just a gimmick. I would rather deal with a quick pin prick if it means the compound actually works. Do you think the delivery method really changes the side effects, or is this just a way to charge more for a "convenient" version?

- jade_s: I feel the same about nasal GLP‑1s – I tried a small trial of inhaled semaglutide in a study a few years ago (still experimental, not commercial). For me the breath‑in felt fine, but the blood test showed only a tiny rise in GLP‑1 levels, and I didn’t notice any change in appetite or glucose. It could be that a higher dose or better formulation would work, but right now the data I saw suggested the bioavailability is much lower than the injection. So I would agree that the convenience may end up
- riley_p: That is interesting that you actually had blood tests to check the levels. Most people just guess based on how they feel, but the data makes it much clearer. For me, I always prefer the most reliable delivery method even if it is less convenient. Do you remember if the study mentioned why the absorption was so low, or was it just a failed formulation?
- bianca703: I never mentioned blood tests, I was just sharing my doubts based on the article. I didn’t see any detail on why absorption might be low; it was only noted as preclinical. Thanks for pointing that out.
- bianca703: That lines up with what I was thinking. I saw the same low bioavailability numbers in the patent data – they were only talking about “partial” absorption. Did the study you were in use any enhancers or just plain aerosol? If they tried something like a permeation aid, I might be more willing to keep an eye on future versions.
