Doesn't it mimic one of the gut incretin hormones (GLP-1, from memory,
and Januvia's a DPP inhibitor, where DPP's the thing that destroys
GLP?), so it only reacts to digested glucose, not liver production -
more sensitive and reactive than a sulf. Not to mention that in mouse
trials, the little beggars grew some beta cells back...

Doh! I really ought to read the whole of a piece before replying... I
think the last sentence is crap. We can make the stuff; the biggest
problem is that we don't make it fast enough to store any, so we don't
have a rush of phase 1 insulin. Then we don't have enough beta cell
mass to make more quickly, and we thrash what's left keeping up,
creating a vicious cycle.
Reading Byetta users' stories, an important feature seems to be loss
of appetite. I'm not sure if that's because of induced nausea, or
because it does something with the leptin/ghrelin cycle too... but for
people who can cope with the nausea, it looks a very cool drug, with
lots of weight loss presumably dropping IR really well, helping
endogenous insulin along. David Mendosa's positively euphoric about
it. The next release looks like it'll be in pill form, too, for those
who don't fancy injections.
If it ever gets down off the rarefied heights of being prescribed only
if you've got poor control on 2+ diabetic drugs, I'd fancy the stuff
myself. Or Januvia, I'm not fussy.
