I am new to this site, but figured i'd try to help you.
heres a nice flashcard tool that you might like. I am not sure if that is what you are looking for, but that is a good start. The most common one you will probably see is -prazole.
Omeprazole (Prilosec generic) is very commonly prescribed for acid-reflux.
I don't know whether you're looking for drug information for just gastroenterology or just basic drug information, but you could look into some basic Sig codes as well. (Sig codes are how a lot of doctors right the directions for a prescription drug. ex: TT PO BID, would equate to 2 tablets twice a day by mouth)
If some of this doesn't make sense, I apologize, it's getting rather late and I'm about to go to bed :P
