....Given the theory that cats absorb and metabolize insulin twice as fast, that would still mean a duration of up to 15 hours for cats...

Hi Carl, yep...you are about right.... But it took me an awful long time to work that one out. It's remarkable how our experience can be coloured by our expectations.... :roll:
I switched to Hypurin because Insuvet PZI was discontinued. At that time people were saying that it was 'basically the same insulin as Insuvet PZI but made/marketed for humans..' So, I was really
expecting it to behave like Insuvet PZI....
First thing I noticed with Hypurin was that my dosage was way too high. I needed to reduce my sliding scale by more than half. At the time I thought this was just because the insulin 'suited Bert better' than the Insuvet. It never occurred to me that it might be because the duration of the insulin was much longer, and that he often had 2 doses working in his system at any one time..... (Duh!!!!)
Then I realised that Bert was - with increasing frequency - going 24 hours on a single shot. And also - most interestingly, that he was sometimes too low to shoot at the regular times but that his BG jumped up at between +15 - +17...... Although that doesn't happen too often, it is exactly that aspect of Hypurin that I find to be a bit of a challenge at times. Sometimes I leave the shot until later, and sometimes experiment with tiny 'mini-shots' to try to extend the cycle; but it is still a work in progress....
That said, Hypurin has been absolutely brilliant for us! I never, ever thought that Bertie would see any decent BG numbers, but he now spends quite long periods in normal numbers, and has lovely flat-bottomed curves too....
I have searched on this forum and also DCC and YDC for more info on this insulin. What I have gleaned is that Hypurin is found to be a good insulin for cats, but the really long duration can
sometimes and in some cats cause a bit of a challenge at times. The onset and peak times also seem to vary a lot from cat to cat, with a wider variation than I've seen happen with other insulins.
But it does seem to be a great insulin for levelling out numbers, probably due to the (sometimes considerable) overlap.
Anyone prescribed this would
definitely need to be hometesting though. Because of Hypurin's long duration it would be absolutely vital to test the BG before giving a shot...
In fact, I wonder if this is why so many UK vets prescribe Caninsulin? At least they can know with a fair degree of certainty that it'll be out of the system in 12 hours....?
