I guess you could look up PPIs 'proton pump inhibitors'. 'prazole mostly.
Dexlansoprazole, esomeprazole, lansoprazole, omeprazole, pantoprazole, rabeprazole.
Not sure if those work but they reduce stomach acid.
I know someone was looking at tagamet i.e. Cimetidine as well. Those are H2 blockers. Famotidine as mentioned above is a H2 blocker.
