Gastritis is a medical term for inflammation of the lining of the stomach. It means that white blood cells move into the wall of the stomach as a response to some type of injury. Gastritis has many underlying causes, from infection with the bacterium H. pylori, bile reflux, or excessive consumption of alcohol or certain foods or drugs like aspirin.

If you're interested in slippery elm, Ulcetrol pills combine PepZin GI, slippery elm, mastic gum, and calcium carbonate (for acid neutralization).

They're larger than PepZin GI in size, but do not qualify as "large pills" in my opinion.
