Pantoprazole
"My gall bladder was acting up and the pain was terrible.  I took a Protonix as soon as I got out of the doctors office (with a sandwich and doctor pepper) about 15 seconds later I was burping like CRAZY.  Viola!! The pain subsided considerably in less than 3 minutes.  AN hour later it was like I never even had the pain!  I felt MUCH, MUCH better."
