Sucralfate
"GERD, Esophagitis, and a Hiatal Hernia. Take both Cimetidine and Prilosec daily and was still having heartburn. The emergency room gave me Carafate and it's wonderful. Not only does it stop heartburn in it's tracks, but it also prevents future bouts of heartburn. 

There are some rules on taking this medication, and those rules can be a bit of a pain if you are not used to them. You cannot take this medication within a half hour of taking any antacids. You also need to take it one hour before or two hours after eating. Swallowing the Carafate pill can be a little bit intimidating as when you swallow it, you get a choking sensation. Make sure to take it with plenty of ice water. Try to numb your throat with cold water prior to taking."
