Interesting that omeprazole in the form of clinically proven GastroGard didn’t yield results but omeprazole in the form of off-shore produced enteric coated granules did? And don’t get me wrong, I use Abler’s granules myself. Did you consider that having her on gastrogard got the healing process started (which omeprazole takes a few days to work to its fullest extent) so you didn’t notice improvement right off, and then coincidentally, you started her on the Abler granules, which continued the healing process, thereby making you think that those worked but the paste did not?
Also, omeprazole does nothing for hindgut ulcers. So, if you found results by using it, your horse probably had gastric ulcers.
